Gastrointestinal parasites of swine raised in different management systems in the State of Rio de Janeiro, Brazil / Parasitos gastrintestinais de suínos criados sob diferentes sistemas de manejo no Estado do Rio de Janeiro

From 2012 to 2013 were surveyed gastrointestinal parasites from pig farms located in different municipalities in the state of Rio de Janeiro. Fecal samples from 790 pigs were collected from the rectum on 88 family farms and 702 farms with industrial production. The samples were subjected to Faust et al., Sheather, Ritchie, Lutz and direct examination faecal techniques. The estimated parasite prevalence was 93.1% in family farms and 59.1% in industrial farms. Balantidium coli, coccidia and Entamoeba sp. were the parasites with the highest frequencies, and the male and female reproductive categories and fatteners pigs the most infected (p<0.05). Trophozoites of B. coli were most evident in stool samples from semi-solid followed by solid and diarrheal consistencies. Strongyles eggs and Trichuris suis have been detected exclusively in family farms. Ascaris suum eggs and Strongyloides ransomi showed low frequency. The high degree of parasitism, especially protozoa, indicates the need to reassess the management of pigs in both types of production...

De 2012 a 2013 foram pesquisados parasitos gastrintestinais de suínos de granjas localizadas em diferentes municípios do estado do Rio de Janeiro. Amostras fecais de 790 suínos foram coletadas da ampola retal, sendo 88 de propriedades familiares e 702 de granjas com produção industrial. As amostras foram submetidas às técnicas de Faust et al., Sheather, Ritchie, Lutz e exame direto. A prevalência estimada foi de 93,1% nas granjas familiares e 59,1% nas granjas industriais. Balantidium coli, coccídios e Entamoeba sp. foram os parasitos que apresentaram as maiores frequências, sendo as categorias machos e fêmeas reprodutoras e leitões de terminação as mais infectadas (p<0,05). Trofozoítas de B. coli foram mais evidenciados nas amostras fecais de consistências semi-sólida, seguida pelas fezes com consistências sólida e diarreica. Ovos de estrongilídeos e Trichuris suis foram detectados exclusivamente em criações familiares. Ovos de Ascaris suum e de Strongyloides ransomi apresentaram baixa frequência. O alto grau de parasitismo, principalmente de protozoários, indica a necessidade de reavaliação do manejo dos suínos em ambos os tipos de produção...

Intestinal parasites in children with diarrhea in Delhi, India.

The parasitic causes of diarrhea in children in Delhi were determined by the direct smear technique; stool specimens of 127 children were examined for intestinal parasites. In 59 cases (46.5%) intestinal helminths and protozoa were demonstrated. Ascaris lumbricoides was observed in 1 (0.8%) case, while Trichuris trichiura was the finding in 3 (2.4%). Protozoal parasites included Giardia intestinalis and Entamoeba histolytica in 14 (11%) cases each, Balantidium coli in 3 (2.4%) cases and Cryptosporidium spp in 24 (18.9%) patients. Mixed infection was not seen in any of the cases. Intestinal parasites may increase susceptibility to infection with other intestinal pathogens and therefore with the help of a simple technique, like direct fecal smear examination. rapid diagnosis can be made and specific therapy instituted.

Balantidiasis en niños: reporte de un caso fatal / Balantidiasis in children: report of a fatal case

Se presenta un caso de balantidiasis fulminante en una niña, procedente de Zarumilla-Tumbes, portadora de colostomía por malformación anorrectal y desnutrición crónica. Las manifestaciones clínicas fueron diarrea disentérica, vómitos y deshidratación, evolucionando con signos de sepsis y abdomen agudo. El diagnóstico de balantidiasis se realizó mediante exámen directo de heces, y el tratamiento inicial con metronidazol y cobertura antibiótica. Ante el curso desfavorable se utilizó tetraciclinas, pero dada su condición de inmunosupresión la paciente fallece. Debemos de considerar esta entidad ante la presencia de las manifestaciones clínicas señaladas en personas que proceden de la frontera con el Ecuador, realizar examen de heces e iniciar tratamiento de primera elección (tetraciclinas), valorando el riesgo-beneficio.

Balantidiasis en una comunidad rural del Estado Bolívar, Venezuela / Balantidiasis in a rural community from Bolivar state, Venezuela

Balantidium coli is the etiologic agent of balantidiasis, an infrequent zoonose of worldwide distribution. The objective of the present study was to determine the clinical and epidemiological aspects of balantidiasis in a rural community in the bolivar state in Venezuela. Fifty persons and 12 pigs were evaluated. Fecal samples were analyzed by direct examination and by the methods of Faust and Willis. The global rate of intestinal parasitoses detected was 88.0 percent for the human population and 83.3 percent for the pigs. The prevalence of human and porcine balantidiais was 12.0 percent (6/50) and 33.3 percent (4/12), respectively. The disease was only detected in children, all of them with multiple parasites and with clinical manifestations. Deficient environmental sanitation, absence of basic services in the dwellings, low socioeconomic level, and the presence of pigs infected with B. coli are the factors that explain and maintain the conditions favorable to the transmission of balantidiasis in the population studied

Gastrointestinal illness associated with balantidium coli infection in rural communities in Ecuador

Un brote de enfermedad gastrointestinal caracterizada por diarrea y heces con sangre fueron investigadas en 4 comunidades diferentes en la provincia de Zamora Chinchipe en Ecuador. Un total de 322 personas fueron examinadas; trofozoitos de Balatidium coli fueron vistos en las heces de 62 de ellas (19,3 por ciento), de estas personas, en el 70,2 por ciento de las personas que tenían diarrea y en el 20.9 por ciento de las que tenían heces sanguinolientas. Así, demostramos una gran asociación entre infección por B. coli y diarrea (p<0,0005). La más alta prevalencia de infección fue vista en niños entre los 6 a 10 años de edad. El orígen de la infección parece provenir de los cerdos, los cuales viven dentro de las casas en pésimas condiciones de higiene. La balantidiasis fue tratada con una combinación de metronidazol y tetraciclina obteniéndose rápida curación

Estudio epidemiológico y coproparasitario de grupos familiares con casos índices de balantidiasis humana en Chiloé / Epidemiologic and coproparasitological study of family groups with balantidiasis in Chiloé

En noviembre de 1983 se estudió a 22 grupos familiares con casos índices de balantidiasis humana en islas de Chiloé (42-43 lat. Sur y 73-74 long. Oeste), para determinar casos nuevos de balantidiasis, frecuencia de las enteroparasitosis y factores epidemiológicos que inciden en estas infecciones. De 133 personas examinadas, 6 presentaron Balantidium coli (4,5%), casos que correspondieron a niños. Los porcentajes de infección por otros parásitos intestinales en las personas fueron las siguientes: Trichuris sp. 84,2%, Ascaris sp. 73,7%, Estamoeba histolytica y Giardia lamblia 6,0%. Entre los factores epidemiológicos destacan: infección de los cerdos por B. coli 78% y Ascaris sp. 42%, crianza de los cerdos a campo abierto 95,5% y, finalmente, pésimas condiciones de saneamiento básico en las viviendas de la población rural
