ABSTRACT

Abstract Present study was conducted among school children to recognize the prevalence of IPIs in rural communities of district Dir Lower, Pakistan. A sum of 324 samples of stool were collected (210 boys and 114 girls). Used direct smear method and formol ether sedimentation concentration technique for processing the samples. The result shows that 82% (n=266) were found infected comprised 64.8% male and 35.1% females. Children of the age group 10 to 12 years were found extremely infected 94.2% while 4-6 year age group were having minimum ratio of infection 72%. Current study shows mono parasitism in 50.6% of the students while 22.2% were infected with 2 species and 7.40% were infected with three species of parasites. Seven species of intestinal parasites were reported include Ascaris lumbricoid in male (n=122) 58.0% and in female (n=65) 57.0% followed by Hook worm (n=88) 41.9% and (n=44) 38.5%; Tania saginata (n=44) 20.9% and (n=24) 21.0%; Entrobius vermicularis (n=32) 15.2% and (n=16) 14.0%; Trichuris trichura (n=25) 11.9% and (n=22) 19.2%; Hymenolepis nana (n=24) 11.4% and (n=18) 15.7% and Entameoba histolytica (n=16) 7.61% and (n=14) 12.2% in male and females respectively. The study indicates that most occurring intestinal parasite in the current study were Ascaris lumbricoides 58.0% (n=122) followed by hookworms 41.9% (n=88). Male students were more infected than females in the present study.

ABSTRACT

Abstract Food handlers plays a primary role in the transmission of pathogenically important protozoans and helminth parasites. This study was aimed to evaluate the prevalence of intestinal pathogenic protozoans and helminth parasites among food handlers in and around University of Malakand, Lower Dir, Pakistan. Stool samples were collected from 642 food handlers (all of male) in a cross-sectional study from January to November, 2017. Wet Mount Techniques and concentration methods by using salt and formol-ether solutions. Three hundred and eighty four cases (59.8%) were found infected with one more parasites. Most of the individuals were found infected with helminth (47.6%) as compared to intestinal protozoans (0.93%). Seventy two cases (11.2%) of the cases presented mixed infection with both intestinal protozoan and helminth parasites. The order of prevalence for intestinal helminth was Ancylostoma duodenale (n = 258, 40.1%), followed by Taeniasa ginata (n=96, 14.9%) Ascaris lumbricoides (n = 54, 8.40%) and Trichuris trichura (n=30, 4.60%). For intestinal protozoa, Entamoeba histolytica/dispar (n = 36, 5.64%) was the only protozoan detected. Mono-parasitism was higher than poly-parasitism. Family size income and education level were the factors significantly (P<0.05) associated in the parasites prevalence. Current research showed that IPIs are primarily the foodborne pathogens still an important public health problem in Pakistan. Effective control programs on parasitic diseases transfer and their associated factors are recommended.


Resumo Os manipuladores de alimentos desempenham um papel fundamental na transmissão de protozoários e helmintos parasitas patogenicamente importantes. Este estudo teve como objetivo avaliar a prevalência de protozoários patogênicos intestinais e helmintos parasitas entre manipuladores de alimentos na Universidade de Malakand, Lower Dir, Paquistão. Amostras de fezes foram coletadas de 642 manipuladores de alimentos (todos do sexo masculino) em um estudo transversal de janeiro a novembro de 2017. Técnicas de montagem úmida e métodos de concentração usando soluções de sal e formol-éter. Trezentos e oitenta e quatro casos (59,8%) foram encontrados infectados com mais um parasita. A maioria dos indivíduos foi encontrada infectada por helmintos (47,6%) em comparação com protozoários intestinais (0,93%). Setenta e dois casos (11,2%) dos casos apresentavam infecção mista com protozoários intestinais e helmintos parasitas. A ordem de prevalência de helmintos intestinais foi Ancylostoma duodenale (n = 258, 40,1%), seguido por Taeniasa ginata (n = 96, 14,9%) Ascaris lumbricoides (n = 54, 8,40%) e Trichuris trichura (n = 30, 4,60 %). Para protozoários intestinais, Entamoeba histolytica / dispar (n = 36, 5,64%) foi o único protozoário detectado. Monoparasitismo foi maior do que poliparasitismo. A renda familiar e o nível de escolaridade foram os fatores significativamente (P <0,05) associados na prevalência de parasitos. A pesquisa atual mostrou que os IPIs são principalmente os patógenos de origem alimentar, ainda um importante problema de saúde pública no Paquistão. Programas eficazes de controle da transferência de doenças parasitárias e seus fatores associados são recomendados.

ABSTRACT

Abstract The objective of the present study was to identify the intestinal parasites with the highest prevalence in anatids that were reared extensively in the city of São Paulo, through coproparasitological examinations. Fecal samples (n=108) were collected at two times, with an interval of two months between them, during the year 2018. The samples were constituted from a pool of feces, and one sample was collected from each enclosure. The samples were identified as belonging to 13 species of anatids (Aix galericulata, Aix sponsa, Anser abyssinia, Chenonetta jubata, Chloephaga melanoptera, Chloephaga picta, Lophodytes cucullatus, Tadorna cana, Tadorna ferrugínea, Tadorna radjah, Tadorna tadorna, Tadorna tadornoide and Tadorna variegata). Samples of birds with or without clinical symptoms of endoparasitosis were then collected. The Coproplus® test was used to make the coproparasitological diagnosis and subsequently the material was examined individually, at Santo Amaro University in São Paulo. It was observed that 48.14% of the enclosures had birds infected by one or more endoparasites. Parasites of the order Coccidia presented the highest prevalence (22.22%), followed by those of the orders Trichuroidea (10.18%) and Ascaridia (4.63%). Moreover, Balantidium sp. was found, the cycle and relevance of these ciliates in birds is uncertain.


Resumo O objetivo do presente estudo foi identificar os parasitos intestinais de maior prevalência em anatídeos provenientes de uma criação extensiva no município de São Paulo, por meio da realização de exame coproparasitológico. Foram coletadas 108 amostras fecais em dois momentos, com intervalo de dois meses entre eles, durante o ano de 2018. As amostras foram constituídas de um pool de fezes, e coletada uma amostra para cada recinto por coleta. Foi realizada a identificação das espécies e estas pertenciam a 13 espécies de anatídeos (Aix galericulata, Aix sponsa, Anser abyssinia, Chenonetta jubata, Chloephaga melanoptera, Chloephaga picta, Lophodytes cucullatus, Tadorna cana, Tadorna ferrugínea, Tadorna radjah, Tadorna tadorna, Tadorna tadornoide e Tadorna variegata). Em seguida foram coletadas as amostras de aves com sintomatologia clínica ou não de endoparasitoses. Para o diagnóstico coproparasitológico e coleta foi utilizado o teste Coproplus® e posteriormente, o material foi examinado individualmente na Universidade Santo Amaro. Observou-se que 48,14% dos recintos possuíam animais infectados por um ou mais endoparasitos. Houve maior prevalência para parasitos da ordem Coccidia (22,22%), seguido pela ordem Trichuroidea (10,18%) e Ascaridia (4,63%) e como achado o Balantidium sp. que possui ciclo e relevância incerta em aves.

ABSTRACT

Abstract This study aimed to identify the intestinal parasites of road-killed wild felines in the North Central and North, Paraná state, southern Brazil. The animals were monitored by sampling previously established transects. The places where the felines were run over were mapped, the animals were identified, and the gastrointestinal tract was evaluated. The feces were submitted to coproparasitological techniques of spontaneous sedimentation, floating in hypersaturated NaCl solution and centrifugal floating in zinc sulfate. All the parasitic structures detected were photomicrographed. In the coproparasitological analyses were identified oocysts of Cystoisospora spp., eggs of Ancylostomatidae, and Capillaria spp.; eggs of Aelurostrongylus spp., Toxocara spp., Physaloptera spp., Taenia spp., and Spirometra spp.; Aelurostrongylus abstrusus larvae; and eggs and adults of Ancylostoma cati and Taenia spp. One of the cats was parasitized by a flea of Ctenocephalides felis felis. Based on these results, the animals analyzed in this study supplied important samples for the evaluation of parasitic diversity of North of Paraná and suggested that this region may have conditions that allow the maintenance of these parasites life cycles in the environment and among wildlife.


Resumo O objetivo deste trabalho foi identificar os parasitas intestinais de felinos silvestres mortos em estradas nas regiões Norte Central e Norte, Paraná, sul do Brasil. Os animais foram monitorados por amostragem de transectos previamente estabelecidos. Os locais de atropelamento foram mapeados, os animais foram identificados e enviados para autópsias, durante as quais amostras de fezes foram coletadas e submetidas a técnicas coproparasitológicas de sedimentação espontânea, flutuação em solução hipersaturada de NaCl e flutuação por centrífugação em sulfato de zinco e fotografadas, quando estruturas parasitárias estavam presentes. Nas análises coproparasitológicas, foram identificados oocistos de Cystoisospora spp., ovos de Ancylostomatidae e Capillaria spp, Aelurostrongylus spp., Toxocara spp., Physaloptera spp., Taenia spp. e Spirometra spp.; larvas de Aelurostrongylus abstrusus; e ovos e adultos de Ancylostoma cati e Taenia spp. Um dos felídeos estava parasitado por Ctenocephalides felis felis. Com base nesses resultados, os animais analisados neste estudo forneceram amostras importantes para a avaliação da diversidade parasitária do Norte do Paraná e sugeriram que esta região pode apresentar condições que possibilitem a manutenção dos ciclos de vida desses parasitas no ambiente e entre a vida silvestre.

ABSTRACT

Abstract INTRODUCTION: Parasitic infections are considered a major public health problem due to their associated morbimortality and negative impact on physical and intellectual development, especially in the at-risk pediatric group. Periodic prophylactic administration of antiparasitic agents against soil-transmitted helminths is recommended by the World Health Organization (WHO) to control parasitic infections and disease burden. We aimed to evaluate the prevalence of intestinal parasitic infections in Brazil. METHODS: We performed a systematic review by searching the literature found in the PubMed, LILACS, and SciELO databases, followed by a meta-analysis of the proportions from studies published in English, Portuguese, and/or Spanish from January 2000 to May 2018. This systematic review was registered in the PROSPERO database (CRD42018096214). RESULTS: The prevalence of intestinal parasitic infections (protozoa and/or helminths) in Brazil was 46% (confidence interval: 39-54%), with 99% heterogeneity. Prevalence varied by region: 37%, 51%, 50%, 58%, and 41% in the Southeast, South, Northeast, North, and Central-West regions, respectively. Most studies (32/40) evaluated children (<18 years) and found an average prevalence of 51%. Children also had the highest prevalence in all four regions: Central-West (65%), South (65%), North (58%), Northeast (53%), and Southeast (37%). However, most studies evaluated specific populations, which may have created selection bias. Presumably, this review of intestinal parasitic diseases in Brazil includes the most studies and the largest population ever considered. CONCLUSIONS The prevalence of intestinal parasitic infections is high in Brazil, and anthelmintic drugs should be administered periodically as a prophylactic measure, as recommended by the WHO.

ABSTRACT

Resumen Se evaluaron retrospectivamente los resultados obtenidos de estudios parasitológicos en muestras de heces y escobillados anales remitidos al Laboratorio de Parasitología y Gastroenterología del Hospital de Pediatría "Prof. Dr. Juan P. Garrahan" de la Ciudad de Buenos Aires, Argentina. El objetivo del trabajo fue conocer la prevalencia de los parásitos intestinales observados en las muestras remitidas a este hospital y su distribución en rangos etarios. En el período comprendido entre mayo de 2018 y abril de 2019 se analizó un total de 4713 muestras pertenecientes a 3311 pacientes, que arrojó un resultado total de 29% de positivos (1371/4713). De los exámenes coproparasitológicos el 30% fueron positivos (1193/4025) y se hallaron huevos de Enterobius vermicularis en el 26% (178/688) de los escobillados anales. En las muestras seriadas de heces se obtuvo un 37% de positividad mientras que en muestras únicas un 21%. En la totalidad de muestras fecales, los enteroparásitos más prevalentes fueron Blastocystis spp. en un 14% (579/4025), Giardia duodenalis 11% (456/4025) y Dientamoeba fragilis 7% (291/4025). Los resultados demostraron diferencias significativas con mayor prevalencia de parásitos intestinales en pacientes en edad escolar comprendidos entre los 6 y 10 años, en relación a los de edad preescolar. En las muestras fecales analizadas se evidenció un predominio de parasitismo de protozoos sobre helmintos, por lo que se debería considerar reforzar el diagnóstico de laboratorio de esas especies mediante técnicas, como coloraciones, que posibiliten su hallazgo y confirmación.


Abstract The results obtained of the coproparasitological studies and anal swab submitted to the laboratory of the Parasitology Section of the Hospital de Pediatría "Prof. Dr. Juan P. Garrahan" of the Buenos Aires City, Argentina, were retrospectively evaluated The aim of this study was to determine the prevalence of intestinal parasites found on the submitted samples and to evaluate their frequency according to the age of the patients. Within the period between May 2018 and April 2019, a total of 4713 samples corresponding to 3311 patients were analyzed and intestinal parasites were present in 29% (1371/4713). In 30% of coproparasitological studies parasite estructures were found (1193/4025) and 26% of anal swab samples were positive for the presence of Enterobius vermicularis eggs (178/688). In serial fecal samples, 37% positive results were obtained, while in single samples, 21%. The most prevalent enteroparasites calculated from the total fecal samples were: Blastocystis spp. with 14% (579/4025), followed by Giardia duodenalis 11% (456/4025) and Dientamoeba fragilis 7% (291/4025). The incidence of intestinal parasites was higher in the group of patients between 6 and 10 years, and the existence of significant differences between proportions of parasitized patients in preschool and school infants, was observed. In the faecal samples analyzed, a greater prevalence of parasitism caused by protozoa than by helminths was evidenced, for which reason it should be considered, reinforcing the laboratory diagnosis using techniques such as stains that allow its finding and confirmation.


Resumo Os resultados obtidos de estudos parasitológicos em amostras fecais e esfregaços anais enviados ao Laboratório de Parasitologia e Gastroenterologia do Hospital de Pediatría "Prof. Dr. Juan P. Garrahan" da Cidade de Buenos Aires, Argentina, foram avaliados retrospectivamente. O objetivo do estudo foi avaliar a prevalência dos parasitas intestinais observados nas amostras enviadas a este hospital e sua distribuição por faixas etárias. Durante o período compreendido entre maio de 2018 a abril de 2019 foram analisadas 4713 amostras, correspondentes a 3311 pacientes, o que deu um resultado total de 29% de positivos (1371/4713). 30% dos exames coproparasitológicos foram positivos (1193/4025) e foram encontrados ovos de Enterobius vermicularis em 26% (178/688) dos esfregaços anais. Nas amostras seriadas fecais foram obtidos 37% de resultados positivos, enquanto que em amostras únicas, 21%. Os enteroparasitas mais prevalentes na totalidade das amostras fecais foram Blastocystis spp. em 14% (579/4025), Giardia duodenalis 11% (456/4025) e Dientamoeba fragilis 7% (291/4025). Os resultados demonstraram diferenças significativas com maior prevalência de parasitas intestinais em pacientes em idade escolar da faixa etária entre 6 e 10 anos, em relação aos da pré-escola. Nas amostras fecais analisadas, evidenciou-se um predomínio de parasitismo por protozoários por sobre helmintos, pelo qual deve ser considerado o reforço do diagnóstico laboratorial dessas espécies por meio de técnicas, como colorações que permitam a sua localização e confirmação.

ABSTRACT

Abstract Parasitological studies of the Franklin's gull, Leucophaeus pipixcan, are scarce, and knowledge about its endoparasites is quite limited. In order to describe its parasitic community, a total of 60 Franklin's gulls were captured in the coastal area in central Chile, using modified Bal-chatri traps. Ectoparasites were collected from all 60 live individuals through inspection of their plumage, while 30 were examined for endoparasites by standard parasitological necropsy. The prevalence of ectoparasites was 78.3%, including the feather mite Zachvatkinia larica (43.3%) and four species of lice: Actornithophilus piceus lari (15.0%), Austromenopon transversum (6.7%), Quadraceps punctatus (10.0%) and Saemundssonia lari (46.7%). Some 25 of 30 (83.3%) of birds necropsied were parasitized with the following helminths: Aporchis sp. (6.7%), Tetrabothrius cylindraceus (56.7%), Cyclophyllidea gen. sp. (3.3%), Profilicollis altmani (56.7%), Eucoleus contortus (10.0%), Cosmocephalus obvelatus (13.3%), Paracuaria adunca (10.0%), Stegophorus sp. (3.3%) and Tetrameres skrjabini (3.3%). To our knowledge, with the exception of P. altmani, these helminths are reported for first time in the Franklin's gull.


Resumo Existem escassos estudos de parasitismo em gaivota-de-Franklin Leucophaeus pipixcan, e o conhecimento sobre seus endoparasitas é ainda mais limitado. Com o objetivo de descrever sua comunidade parasitaria, um total de 60 gaivotas-de-Franklin foram capturadas usando-se armadilhas Bal-chatri numa zona costeira do centro do Chile. A pesquisa de ectoparasitas foi realizada em todos os indivíduos capturados e, para os endoparasitas, foram examinados 30 deles por necropsias. A prevalência de ectoparasitas foi de 78,3%, incluíndo o ácaro de pena Zachvatkinia larica (43,3%) e outras quatro espécies de piolhos, Actornithophilus piceus lari (15,0%), Austromenopon transversum (6,7%), Quadraceps punctatus (10,0%) e Saemundssonia lari (46,7%). Das aves necropsiadas, 83,3% estavam parasitadas por helmintos, sendo registrados Aporchis sp. (6,7%), Tetrabothrius cylindraceus (56,7%), Cyclophyllidea gen. sp. (3,3%), Profilicollis altmani (56,7%), Eucoleus contortus (10,0%), Cosmocephalus obvelatus (13,3%), Paracuaria adunca (10,0%), Stegophorus sp. (3,3%) e Tetrameres skrjabini (3,3%). Com exceção de P. altmani, este é o primeiro relato desses helmintos parasitando gaivotas-de-Franklin.

ABSTRACT

Abstract Backyard pigs have been associated with poor sanitary conditions and the development of parasitic diseases, often causing public health and food safety problems. Therefore, the aim of this study was to determine the prevalence and risk factors for gastrointestinal parasites in backyard pigs. 279 animals were sampled from thirty-two backyard pig farms located in the Bucaramanga, Floridablanca, Giron and Piedecuesta municipalities, from Bucaramanga Metropolitan Area, Colombia. Fecal samples were taken directly from the rectum and processed by four coprological techniques. The overall prevalence of gastrointestinal parasites was 91%, being the highest values for Balantidium coli and Eimeria sp. Regarding the prevalence by municipalities, there was no statistical association (p ≥ 0.05) indicating that the prevalence was similar in the region under study. Floridablanca municipality, free-ranging pigs, access to latrines, and consumption of spring water showed to be a risk factor for nematodes, while Giron municipality, pigs > 7 months of age and access to latrines, increased infection risk for coccidian. We concluded that there is a high prevalence of gastrointestinal parasites in backyard pigs from the Bucaramanga Metropolitan Area, and that it could be controlled by improving management practices and farm facilities.


Resumo Suínos criados em fundo de quintal têm sido associados às más condições sanitárias e ao desenvolvimento de doenças parasitárias, frequentemente causando problemas de saúde pública e segurança alimentar. Assim, o objetivo deste estudo foi determinar a prevalência e os fatores de risco para parasitos gastrointestinais em suínos criados em fundo de quintal. Foram amostrados 279 animais de 32 fazendas de suínos localizadas nos municípios de Bucaramanga, Floridablanca, Giron e Piedecuesta, da Área Metropolitana de Bucaramanga, Colômbia. As amostras fecais foram coletadas diretamente do reto e processadas por quatro técnicas coprológicas. A prevalência geral de parasitos gastrintestinais foi de 91%, sendo os maiores valores para Balantidium coli e Eimeria sp. Em relação à prevalência por municípios, não houve associação estatística (p≥ 0,05), indicando que a prevalência foi semelhante na região estudada. O município de Floridablanca, porcos caipiras, acesso a latrinas e consumo de água da nascente mostraram ser um fator de risco para os nematoides enquanto no município de Giron, porcos com mais de 7 meses de idade e acesso a latrinas, aumentou o risco de infecção por coccídios. Concluiu-se que há uma alta prevalência de parasitos gastrointestinais em suínos criados em fundo de quintal da Área Metropolitana de Bucaramanga, e que isso poderia ser controlado melhorando as práticas de manejo e as instalações agrícolas.

Abstract Dogs play a potential role as reservoirs for zoonotic parasites, being especially problematic uncontrolled dog populations such as stray and farm dogs with access to populated areas. In order to investigate the prevalence of canine intestinal parasites in at-risk dog populations, we tested a total of 233 faecal samples shed by stray and dairy farm dogs from northern Spain. Telemann method was used to detect the presence of eggs and (oo)cysts of common dog intestinal parasites and Cryptosporidium was detected by PCR. One hundred and forty eight out of 233 samples (63.5%) were positive for at least one intestinal parasite, being Ancylostomidae (35.6%; 83/233) and Trichuris (35.2%; 82/233) the parasites most frequently identified. Cryptosporidium DNA was not detected in any of the faecal samples analysed. The overall prevalence was significantly higher in stray dogs than in farm dogs (72.5% vs 58.8%). Specifically, stray dogs had a significantly higher prevalence of Ancylostomatidae, Toxocara, Toxascaris and Taenidae. These dog populations are an important source of environmental contamination with intestinal parasite forms, which could be of significance to animal and human health.


Resumo Os cães desempenham um importante papel como reservatório de parasitos zoonóticos, sendo especialmente problemáticas as populações descontroladas, como a de cães errantes e de fazenda, com acesso às áreas povoadas. Para investigar a prevalência de parasitos intestinais em populações caninas de risco, foram analisadas 233 amostras fecais provenientes de cães de fazendas leiteiras e errantes do norte da Espanha. O método Telemann foi utilizado para detectar ovos, cistos e oocistos dos parasitos caninos mais comuns e para a detecção de Cryptosporidium foi utilizada a técnica da PCR. Cento e quarenta e oito de 233 amostras analisadas (63,5%) foram positivas para pelo menos um parasito intestinal, sendo Ancyostomatidae (35,6%; 83/233) e Trichuris sp. (35,2%; 82/233) os parasitos identificados com maior frequência. O DNA de Cryptosporidium sp. não foi detectado em nenhuma das amostras fecais analisadas. A prevalência geral foi significativamente maior em cães errantes do que em cães de fazenda (72,5% vs 58,8%). Especificamente, os cães errantes tiveram prevalência maior para Ancylostomatidae, Toxocara, Toxascaris e Taenidae. Essas populações de cães são importantes fontes de contaminação ambiental, pois eliminam formas de vida desses parasitos, que podem ter impacto na saúde animal e humana.

ABSTRACT

RESUMEN Objetivos Establecer la relación entre parasitismo intestinal en niños menores de 6 años y vivienda en áreas de protección ambiental, sin servicio de acueducto, en El Codito -Bogotá, Colombia. Métodos Estudio de corte transversal que incluyó 144 niños entre los 4 y 70 meses de edad. Se recolectaron datos sociodemográficos encuestando a los padres y se tomaron muestras fecales de los niños. Se calcularon medidas descriptivas de las variables por tipo de población (parasitada y no parasitada) estableciendo diferencias estadísticamente significativas. Utilizando una regresión logística binomial multivariada se determinó la relación entre parasitismo intestinal y servicio de acueducto, controlando por las demás variables estudiadas. Resultados Se encontró una prevalencia de parasitismo intestinal de 38,9%. La falta de servicio de acueducto estuvo asociada a parasitismo (OR=31,25) ajustando por las demás variables estudiadas. Otras variables asociadas a parasitismo fueron: afiliación al régimen de salud subsidiado al compararla con el contributivo (OR=1,49), presencia de animales en la vivienda (OR=2,58), madres con oficio técnico-profesional al compararlas con madres con oficios no calificados (OR=0,05) y vivienda en habitación rentada al compararla con vivienda propia (OR=6,62). Conclusiones Los niños menores de 6 años viviendo en áreas protegidas sin servicio de acueducto presentaron con mayor frecuencia parasitismo intestinal. Si bien es claro que el establecimiento de áreas protegidas para preservar el medio ambiente es esencial, si no se previene el asentamiento de poblaciones en estos territorios a tiempo, la población que habita en los mismos está sujeta a condiciones adversas que atentan contra la dignidad humana.(AU)


ABSTRACT Objective To establish the correlation between intestinal parasitism in children younger than 6 years old and their dwelling in environmental protected areas without aqueduct service, in the neighborhood El Codito, in Bogotá, Colombia. Materials and Methods A cross-sectional study was done with 144 children between the ages of 4 and 70 months. Socio-demographic data were collected by surveying parents, and fecal samples were taken from the children to identify parasites. Descriptive measures were calculated for the variables by population type (parasitized and non-parasitized), establishing significant differences. Using a binary multivariate logistic regression, the correlation between intestinal parasitism and aqueduct was determined, adjusting the other studied variables. Results The prevalence of intestinal parasitism was 38.9%. The lack of aqueduct service was associated with intestinal parasitism (OR=31.25) after adjusting for other studied variables, which included affiliation to the subsidized health insurance regime compared with the contributory regime (OR= 1.49), home pets (OR= 2.58), mothers with professional jobs compared to mothers with non-professional jobs (OR=0.05), and dwelling in a rented room when compared with own dwelling (OR= 6.62). Conclusions Children under the age of 6 living in protected areas without water service were more likely to suffer from intestinal parasitism. It is known that preserving protected areas to protect the environment is of great importance, but if the settlement of populations in these territories is not prevented in time, the population living there is subject to adverse conditions which violate human dignity.(AU)

ABSTRACT

Abstract Background: The state of Chiapas has held the first place of extreme poverty in Mexico. The majority of Chiapas' municipalities are inhabited by marginalized, indigenous populations, who usually present diarrhea of unknown etiology. We evaluated the nutritional status, intestinal parasites, and common bacterial pathogens, including DEC (diarrheagenic Escherichia coli) strains, in 178 children under five years of age with a high (rural) and a moderate (urban) degree of marginalization. Methods: Z-scores for anthropometric indexes from the children were obtained, whereas intestinal parasites were investigated by using a direct coproparasitoscopic analysis and a concentration method. DEC strains were detected by polymerase chain reaction (PCR). Results: The stunting prevalence in children from the rural and urban regions was 79.8 and 7.5%, respectively. Only children from rural municipalities were parasitized (72.6%), being Ascaris lumbricoides and Entamoeba histolytica/Entamoeba dispar the most prevalent parasites (57.1 and 38.1%, respectively). More than half of the children presented moderated ascariasis. Besides Giardia intestinalis, these parasites were associated with stunting. The prevalence of DEC strains was similar in both regions. Conclusions: Only children from the Chiapas Highlands (rural zone) exhibited high prevalences of stunting and intestinal parasites. A reevaluation of social development programs should be in place to address stunting and intestinal parasitoses, mainly in rural regions of Chiapas, to avoid adverse functional consequences on these children.


Resumen Introducción: El estado de Chiapas ha ostentado el primer lugar de pobreza extrema en México. La mayor parte de la población de los municipios de Chiapas es indígena, vive en condiciones de marginación y padece de diarrea de etiología desconocida. Este trabajo evaluó el estado nutricional, la presencia de parásitos intestinales y patógenos bacterianos comunes, además de cepas DEC (Escherichia coli diarreogénica) en 178 niños menores de cinco años, provenientes de una localidad con alto grado de marginación (rural) y de una con moderada marginación (urbana). Métodos: Se obtuvieron los puntajes Z de los índices antropométricos de los niños. Los parásitos intestinales se investigaron con el método coproparasitoscópico directo y un método de concentración. Las cepas DEC se detectaron mediante reacción en cadena de la polimerasa. Resultados: La prevalencia de desmedro en niños de la zona rural y urbana fue de 79.8 y 7.5%, respectivamente. Únicamente los niños de la zona rural estuvieron parasitados (72.6%), y los más prevalentes fueron Ascaris lumbricoides y Entamoeba histolytica/Entamoeba dispar (57.1 y 38.1%, respectivamente). Más de la mitad de los infantes exhibieron ascariasis moderada. Estos parásitos, además de Giardia intestinalis, se asociaron con el desmedro. En ambas regiones, la prevalencia de DEC fue similar. Conclusiones: Solo los niños de los Altos de Chiapas (zona rural) exhibieron alta prevalencia de desmedro y parásitos intestinales. Para evitar las consecuencias adversas entre los infantes, es necesario reevaluar los programas de desarrollo social para combatir el desmedro y la parasitosis intestinal, principalmente en las regiones rurales de Chiapas.

ABSTRACT

Abstract Intestinal parasitic infections in immunocompromised patients can lead to serious complications when not diagnosed and treated early. This study aimed to investigate the frequency of intestinal parasites in cancer patients undergoing chemotherapy in the South of Brazil. Three fecal samples collected from each patient (73 individuals) were processed by Ritchie and Faust techniques and submitted to specific staining methods for intestinal protozoa. A 61.6% parasite and/or commensal positivity was found. Helminths identified were Ascaris lumbricoides (33.3%), Taenia spp. (6.6%), Strongyloides stercoralis (4.4%) and Trichuris trichiura (2.2%). Among protozoans, Giardia lamblia (26.6%), Cryptosporidium spp. (13.3%) and Cystoisospora belli (4.4%) were identified. The presence of Entamoeba coli, Endolimax nana and Entamoeba hartmanni was also recorded. The results obtained warn of the importance of fecal parasitological diagnosis and the use of specific staining methods for the detection of intestinal parasites in cancer patients. These exams should be regularly requested at the patient's first clinic visit, given the high prevalence found in this study and the possible severity of such conditions for these individuals.


Resumo As parasitoses intestinais em pacientes imunocomprometidos podem levar a graves complicações se não diagnosticadas e tratadas precocemente. Este estudo teve como objetivo investigar a frequência de parasitos intestinais em pacientes oncológicos submetidos ao tratamento quimioterápico. Foram coletadas três amostras de fezes de cada paciente, sendo processadas pelas técnicas de Ritchie e Faust e submetidas à métodos de coloração específicos para protozoários intestinais. Foi encontrada positividade de 61,6% para parasitos e/ou comensais. Os helmintos identificados foram Ascaris lumbricoides (33,3%), Taenia spp. (6,6%), Strongyloides stercoralis (4,4%) e Trichuris trichiura (2,2%). Dentre os protozoários, foram identificados Giardia lamblia (26,6%), Cryptosporidium spp. (13,3%) e Cystoisospora belli (4,4%). Também foi registrada presença de Entamoeba coli, Endolimax nana e Entamoeba hartmanni. Os resultados encontrados alertam para a importância do diagnóstico parasitológico de fezes junto à utilização de colorações específicas para parasitos intestinais em pacientes oncológicos, sendo que os mesmos deveriam ser requeridos como conduta já na primeira consulta clínica destes pacientes, dada à elevada prevalência aqui constatada e a possível severidade que tais moléstias podem acarretar nestes indivíduos.

ABSTRACT

Introducción: Los parásitos intestinales tienen alto impacto en la salud de la población mundial y pueden constituir un factor más de riesgo en poblaciones en alto grado de vulnerabilidad por desplazamientos humanos a causa de la pobreza, violencia o catástrofes naturales. Objetivo: Evaluar el parasitismo intestinal en los habitantes de dos asentamientos humanos en alto grado de vulnerabilidad. Métodos: estudio descriptivo de corte transversal, en el que se analizaron 367 muestras fecales de los habitantes de dos asentamientos humanos en estado de vulnerabilidad del departamento del Atlántico-Colombia, durante los años 2015 y 2016. Se realizó examen directo de las heces en solución salina, lugol y concentración con el método formol-éter. Se estableció la frecuencia absoluta y relativa de los parásitos presentes y se compararon los resultados entre los dos lugares de muestreo. Resultados: el 91,28 por ciento de la población analizada tenía parásitos intestinales. Las helmintiasis presentaron una frecuencia del 52,32 por ciento. Los parásitos más frecuentes fueron Blastocystis sp. (49,05 por ciento) y Trichuris trichiura (44,96 por ciento). Conclusiones: La alta prevalencia de parásitos en las poblaciones vulnerables analizadas, plantea la necesidad de implementar estrategias para el control del parasitismo intestinal dentro de los planes de prevención y mitigación de riesgos(AU)


Introduction: Intestinal parasites have high impact in the health of the world population and can constitute another risk factor in populations with a high degree of vulnerability by human displacements because of poverty, violence or natural catastrophes. Objective: To evaluate intestinal parasitism in inhabitants of two populations with high degree of vulnerability. Methods: Cross sectional, descriptive study in which 367 stool samples were analyzed from the inhabitants of two populations with high vulnerability's degree, in Atlántico-Colombia department during the years 2015 and 2016. The parasitological analysis was performed by direct examination of the stool samples in saline, lugol and concentration solutions by the formalin-ether method. The absolute and relative frequencies of the parasites present were established and the results between the sampled places were compared. Results: 91.28 percent of the population was infected with intestinal parasites. Helminthiasis showed a frequency of 52.32 percent. The most frequents parasites were Blastocystis sp. (49.05 percent) and Trichuris trichiura (44.96 percent). Conclusions: The high prevalence of parasites in the analyzed populations with a high degree of vulnerability expresses the need of implementing strategies for the control of intestinal parasitism in the prevention and risk's mitigation planning(AU)

ABSTRACT

RESUMEN Introducción: la prevalencia de las infecciones parasitarias intestinales en niños no ha variado mucho en Cuba en los últimos años. Objetivo: determinar la prevalencia de las infecciones parasitarias intestinales e identificar los factores asociados en los círculos infantiles de un Consejo popular de Matanzas. Materiales y métodos: se realizó un estudio analítico, transversal, entre octubre de 2014 y abril de 2015 en el cual se incluyeron niños que asistían a esos círculos infantiles. Se utilizó un muestreo sistemático para la selección. La información se recogió a través de una entrevista estructurada y sé colectaron dos muestras fecales, en días alternos. Cada muestra fue procesada con dos métodos coproparasitológicos. Se estudiaron variables sociodemográficas y factores higiénicos sanitarios. En el procesamiento estadístico se calcularon las frecuencias absolutas, relativas y el Odds Ratio. Se realizó un análisis bivariado y se controlaron los posibles factores de confusión utilizando la regresión logística del programa SPSS. Resultados: 93 niños estaban infectados por algún parásito o comensal. Blastocystis sp., Giardia lamblia y E. histolytica/ E. dispar resultaron los parásitos más frecuentes. La calidad del agua de consumo, comerse las uñas o chuparse el dedo, así como el no lavado de las manos fueron identificados como factores asociados al parasitismo, el resto de los factores resultaron de confusión. Conclusiones: la mitad de los niños se encontraban parasitados, lo que demuestra que las condiciones higiénicas y la educación sanitaria en estas instituciones están aún por debajo del nivel deseado por el sistema nacional de salud (AU).


ABSTRACT Introduction: the prevalence of intestinal parasitic infections in children has not changed in Cuba in the last years in spite of the efforts made by the National Public Health System. Objective: to determine the prevalence of the intestinal parasitic infections and to identify the factors associated to them in the day care centers of the Popular Council Matanzas. Material and methods: a cross-sectional, analytical study was carried out in the period from October 2014 till April 2015 in children assisting those day care centers. The sample was chosen by a systematic sampling. Information was gathered through a structured interview and two stool samples were collected after a day. Each stool sample was processed using two different stool parasitological methods. Socio-demographic variables and hygienic-sanitary factors were studied. Odds ratio, relative and absolute frequencies were calculated during statistic processing. A bivariate analysis was made and the main possible confusion variants were controlled using the SPSS program logistic regression. Results: 93 children were infected by any parasite or commensal, predominating monoparasitism. Blastocystis sp., Giardia lamblia and E. histolytica /E. dispar were the most frequent parasites. Drinking water quality, nails biting or fingers sucking, as well as no hand washing were identified as factors associated to parasitism; the rest of the factors were confusing. Conclusions: half of the patients were found parasite carriers, showing that hygienic conditions and sanitary education in these institutions are still under the level desired by the National Health System (AU).

ABSTRACT

Abstract With the aim to identify the parasite fauna of plumbeous rail, Pardirallus sanguinolentus (Aves: Rallidae) in Chile, 26 carcasses were parasitologically necropsied. The present study revealed the presence of 14 species of parasites (inverse Simpson index = 4.64; evenness = 0.332), including ectoparasites: feather mites: Analloptes megnini , Grallobia sp., Grallolichus sp., Megniniella sp., and Metanalges sp.; the feather lice Pseudomenopon meinertzhageni, Rallicola andinus, and Fulicoffula sp.; and six species of gastrointestinal helminths: Heterakis psophiae, Porrocaecum ardeae, Tetrameres sp., Capillaria sp., Diorchis sp., and Plagiorhynchus sp. The relatively high parasite richness that was found could be attributed to the highly favorable conditions of wetlands for parasite development. All parasites found, except feather lice, are new records for plumbeous rail. A checklist of parasites for plumbeous rail is presented.


Resumo Com o objetivo de identificar a fauna parasitária do saracura-do-banhado, Pardirallus sanguinolentus (Aves: Rallidae) no Chile, 26 carcaças foram necropsiadas. O presente estudo revelou a presença de 14 espécies de parasitos (índice Simpson inverso = 4,64; equitatividade = 0,332), incluindo os ácaros de penas: Analloptes megnini, Grallobia sp., Grallolichus sp., Megniniella sp. e Metanalges sp.; os piolhos de penas Pseudomenopon meinertzhageni, Rallicola andinus e Fulicoffula sp.; e seis espécies de helmintos gastrointestinais: Heterakis psophiae, Porrocaecum ardeae, Tetrameres sp., Capillaria sp., Diorchis sp. e Plagiorhynchus sp. A riqueza parasitária relativa encontrada pode ser devido às condições altamente favoráveis das zonas úmidas para o desenvolvimento do parasita. Todos os parasitos encontrados, com exceção dos piolhos de pena, são novos registros para o saracura-do-banhado. Um checklist dos parasitos do saracura-do-banhado é apresentado.

ABSTRACT

ABSTRACT BACKGROUND: Enteral parasitic diseases are a public health problem in nations with low economic development and in settings with poor sanitation. Amebiasis is the second most frequent form of parasitosis, with a high burden of disease. Knowledge of the prevalence of enteroparasitoses in a given region is useful for planning clinical decision-making. Thus, the aim of this study was to estimate the prevalence of enteral parasitic diseases, especially amebiasis, through analysis on stool samples from public and private laboratories in a metropolitan area in southeastern Brazil. DESIGN AND SETTING: Cross-sectional study conducted in the metropolitan region of Belo Horizonte, Brazil. METHODS: We evaluated 6,289 fecal samples from one private and one public laboratory. The samples were concentrated by means of spontaneous sedimentation, and those that were positive for Entamoeba histolytica or Entamoeba dispar in optical microscopy analyses were processed to obtain deoxyribonucleic acid, with subsequent identification through the polymerase chain reaction. RESULTS: Among the stool samples, 942 (15.0%) had parasitic infections; 73 (1.2%) of these were helminthic infections and 847 (13.5%) were protozoan infections, caused mainly by Escherichia coli (6.0%), Endolimax nana (5.2%) and Giardia lamblia (1.2%). Infections due to Entamoeba histolytica or Entamoeba dispar occurred in 36 samples (0.6%) and the polymerase chain reaction revealed five (13.9%) as Entamoeba histolytica. CONCLUSION: The prevalence of enteral parasitic diseases is high in the metropolitan region of Belo Horizonte, although amebiasis may not be a problem.

ABSTRACT

Abstract The objective of this study was to determine the parasitological profiles of traction equids from the semi-arid climate of Paraíba (PB) State. We analyzed 96 equids that performed traction work, with no defined breed, males and females, and all older than 24 months. Among the analyzed animals, 51% were donkeys, 41.7% mules, and 7.3% horses. Fecal material and blood were collected for parasitological examination and to determine the packed cell volume (PCV), respectively. The samples were sent to the Veterinary Parasitology Laboratory, Veterinary Hospital - IFPB, Sousa-PB campus, and epidemiological questionnaires were provided to the owners. It was observed that 83.3% of equids tested positive for gastrointestinal parasites. Strongylidae was the most prevalent parasite (83.3%), followed by Giardia sp. (5.3%), and Eimeria sp. (2.1%). The mean eggs per gram (EPG) value of the fecal samples was 1143. Fecal analysis revealed that 78.9% of the larvae were from "small strongyles". The presence of ectoparasites was not observed in the studied animals. The answers to our questionnaire revealed that 69.8% of the animals had never been dewormed and that the remaining 31.2% had only been dewormed once. We concluded that the prevalence of gastrointestinal parasites among traction equids in the municipality of Sousa-PB is high.


Resumo Objetivou-se determinar o perfil parasitológico de equídeos carroceiros no município de Sousa, Sertão da Paraíba. Foram analisados 96 equídeos que realizavam trabalho de tração, sem raça definida, machos e fêmeas, idade superior a 24 meses. Dentre os animais analisados 51% foram asininos, 41,7% muares e 7,3% equinos. Foi coletado material fecal para exames coproparasitológicos e sanguíneo para determinação do volume globular (VG), encaminhados ao Laboratório de Parasitologia Veterinária, Hospital Veterinário - IFPB, campus Sousa-PB. Foi aplicado questionários epidemiológicos aos proprietários. Observou-se que 83,3% dos equídeos carroceiros foram positivos nos exames parasitológicos fecais. Os Estrongilídeos foram os parasitos mais prevalentes (83,3%), seguidos por Giardia sp. (5,3%). e Eimeria sp. (2,1%). A média de OPG dos equídeos carroceiros foi 1143. Nas coproculturas, constatou-se que 78,9% das larvas eram de "pequenos estrôngilos". Não foi observada a presença de ectoparasitas. Em 69,8% dos animais nunca haviam sido vermifugados e os demais 31,2% apenas uma vez. Concluiu-se que é alta a prevalência de parasitos gastrintestinais em equídeos carroceiros do município de Sousa-PB.

Summary: Introduction: iron deficiency anemia, nutritional alterations and intestinal parasitic diseases, mainly giardiasis and soil-transmitted helminthiasis (HTS) are prevalent problems in Uruguay, which determine consequences for individual and collective health. Objective: to determine the prevalence of anemia, nutritional alterations and enteroparasitosis in children of 6-48 months of a vulnerable population of Montevideo, to establish possible synergisms and to analyze the presence of risk factors. Material and methods: descriptive, cross-sectional study. Population: children aged 6-48 months belonging to a program to support vulnerable homes in Montevideo. Students and teachers of Medicine and Nutrition trained, attended the homes and through surveys, collected demographic, environmental, epidemiological, clinical and habits variables, between October / 2014-May / 2015. They performed anthropometric measures, capillary hemoglobin and coproparasitary. Data analysis: EPIinfo2000 complemented with SPSS19. Statistical analysis: uni or multivariate. Associations between 2 variables: test of Z or chi². Associations between more than 2 variables: multiple regressions. Protocol approved by the Ethics Committee of the School of Medicine. Results: N: 136 children. Prevalence of anemia: 33%, low weight: 3.7%, size retardation: 18% and overweight / obesity: 4.5%. They harbored pathogenic parasites: 60% of those studied; Giardiasis: 46% and HTS: 23%, polyparasites: 13%. Conditions that presented association with HTS: flood zone, alternatives of sanitation not improved and elimination of open pit. Significant associations found: between HTS and anemia; and between HTS and height deficit (group of 1-2 years). Conclusions: the results are worrying given the high prevalence of anemia, nutritional alterations and parasites in this population. The planning and implementation of measures with multidisciplinary, inter-institutional and community participation is urgently needed.

Resultados: N: 136 crianças. Prevalência de anemia: 33%, baixo peso: 3,7%, atraso na altura: 18% sobrepeso / obesidade: 4,5%. Parásitos patogênicos: 60%; Giardíase: 46% e HTS: 23%, poliparasitizados: 13%. Condições que apresentaram associação com HTS: zonas de inundação, alternativas precárias de saneamento e disposição de resíduos a céu aberto. Associações significativas encontradas: entre HTS e anemia; e entre HTS e déficit de altura (grupo de 1-2 anos). Conclusões: os resultados são preocupantes, dada a alta prevalência de anemia, alterações nutricionais e parasitoses nessa população. É fundamental o planejamento e execução de medidas tais como participação multidisciplinar, interinstitucional e comunitária.
