ABSTRACT

Abstract This study aimed to evaluate foraging distance (FD) from the dung, parasitological and physiological factors in 18 Crioula Lanada lambs naturally infected by nematodes with three infection levels (IL) in a Voisin Grazing System. In the pre-experimental phase animal feces collection, deworming, observer training, animal adaptation and dung demarcation were carried out; in the experimental phase, grazing distance, feces, pasture and blood sampling. An initial exploratory analysis was carried out (Kruskal-Wallis test). Fixed predictors were selected with a cumulative logit regression model; an ordinal logistic regression mixed model identified influencing factors of ordinal responses for (i) FD, (ii) infective larvae quantity (L3). Animals approached the dung when the radiation or temperature were more intense (P < 0.05). Paddock entry/exit, IgG and L3 influenced FD over time (P < 0.05). L3, in turn, was influenced by IL, FEC and corpuscular volume (CV). In the High IL group, FD varied between 60-100 cm. Greater L3 and FEC were found in the High and Low IL from the 4th week (P < 0.05). Naturally infected Crioula Lanada lambs increased the distance from the dung, which was not related to IL but to the dynamics of solar radiation and parasitological and immunological factors.


Resumo O objetivo deste estudo foi avaliar a distância de forrageamento do bolo fecal (DF), fatores parasitológicos e fisiológicos em 18 cordeiros Crioula Lanada, naturalmente infectados por nematoides com três níveis de infecção (NI) em sistema Pastoreio Racional Voisin (PRV). Na fase pré-experimental, houve coleta de fezes dos animais, vermifugação, treinamento de observadores, adaptação dos animais e demarcação do bolo fecal; na fase experimental, distância, fezes, pastagem e sangue. Um modelo de regressão "logit" cumulativa selecionou preditores fixos; um modelo misto de regressão logística ordinal identificou fatores influenciadores das respostas ordinais para (i) DF (ii) quantidade de larva infectante (L3). Os cordeiros se aproximaram do bolo fecal quando a radiação ou temperatura foram mais intensas (P < 0,05). A entrada e a saída dos piquetes, a ingestão de L3 e IgG influenciaram DF (P < 0,05). L3 foi influenciada por NI, OPG e volume corpuscular. O grupo NI Alta variou a distância entre 60-100 cm. Maior L3 e a FEC foram encontrados nos grupos NI Alta e Baixa a partir da 4ª semana (P < 0,05). Cordeiros Crioula Lanada, naturalmente infectados, aumentaram a DF, sem relação com nível, de infecção, mas com a dinâmica da radiação solar e dos fatores parasitológicos e imunológicos.

ABSTRACT

RESUMO A industrialização da agricultura e da pecuária, além de gerar um ambiente propício à disseminação de agentes infecciosos, é responsável pelo uso generalizado de diversas substâncias tóxicas que afetam a saúde humana, animal e ambiental. O objetivo deste estudo foi promover a reflexão sobre o uso de agrotóxicos e medicamentos veterinários como elementos de debate na construção da Saúde Única. Para isso, foi realizada uma revisão exploratória literária de artigos, livros e documentos oficiais disponíveis em plataformas de banco de dados. A discussão inclui as problemáticas do uso de substâncias tóxicas em plantas e animais. Aborda, também, como os resíduos oriundos de sua utilização impactam a qualidade de alimentos, ar, solo, água com consequências à saúde humana. Embora essa discussão seja escassa na temática de Saúde Única, é fundamental que, além da participação da sociedade civil organizada, gestores públicos assegurem, por meio de políticas públicas, maior segurança e controle na utilização de substâncias tóxicas na agricultura e na pecuária.


ABSTRACT The industrialization of agriculture and livestock, in addition to generating an environment conducive to the spread of infectious agents, is responsible for the widespread use of various toxic substances that affect human, animal, and environmental health. This study aims to promote reflections on the use of pesticides and veterinary drugs as elements of debate in the construction of One Health. For that, an exploratory literature review of articles, books, and official documents available on database platforms was carried out. The discussion includes the problems of the use of toxic substances in plants and animals. It also addresses how the waste arising from its use impacts the quality of food, air, soil, and water, with consequences for human health. Although this discussion is scarce on the theme of One Health, it is essential that, in addition to the participation of organized civil society, public managers ensure, through public policies, greater security and control in the use of toxic substances in agriculture and livestock.

ABSTRACT

Anamnesis and homeopathic repertorization are essential steps for collecting symptoms and selecting the suitable medicine to cure vegetables presenting pathologies or changes in homeostasis. Aims: The objective of this study was to carry out observation, anamnesis, and homeopathic repertorization of bell pepper plants and their cultivation environment and select thesimillimummedicine for the culture. Methods The study was performed at the Research and Extension Center in Agroecology of Ressacada Experimental Farm -Center of Agrarian Sciences, Federal University of Santa Catarina,Florianópolis, Brazil. The selection of symptoms was based on the characteristics of the diseases observed in the plants and modalized by evidenced characteristics in the environment. Symptomswere chosen by the mechanical method without hierarchization and a master symptom, and after their analogy with the symptoms described in the Homeopathic Materia Medica. Results The choice forCalcarea carbonicaandSulphurdrugs was based on the number of covered symptoms and the score obtained during the digital repertorization performed by the software HomeoPro®. The chosen dilution, 30 CH, was based on the miasmatic magnitude presented by the symptoms. Conclusion: The analogy of symptoms found in the agricultural organism with the symptoms described in the Homeopathic Materia Medica presents a promising path for choosing medicine to cure diseases in vegetables. The choice of the appropriate homeopathic medicine for crops must represent the symptomatic totality presented by the plant and by the environment in the homeopathic repertorization.

ABSTRACT

In Brazil, dogs and cats have free access in public areas in some cities, such as squares, parks and beaches, despite restrictive laws for their permanence in these places. Animals infected with intestinal parasites contaminate the environment through their feces. The present study aimed to verify the occurrence of helminth eggs, oocysts and protozoan cysts in stool samples from three beaches in Greater Florianópolis, Santa Catarina, Brazil, from March 2017 to April 2018. Stool samples were processed by the Willis-Mollay flotation technique and the Hoffman sedimentation technique. The percentage of 47.65% of positive samples for helminths or protozoa was found on the southern beaches of Florianópolis island, with an occurrence of 52.78% at Morro das Pedras Beach and 42.86% at Campeche Beach. At Pinheira beach, in Palhoça, 56.66% of the samples were contaminated with one or more zoonotic parasites. In this study, the most prevalent parasites on the three beaches analyzed were hookworms and Trichuris vulpis, followed by Giardia spp. and Cystoisospora spp. Samples containing To x o c a r a spp. eggs were collected at Pinheira beach. It is concluded that the contamination of the beaches in the present study constitutes a public health problem, considering the possibility of zoonoses transmission. The importance of implementing sanitary programs for the control of parasites in dogs and cats is emphasized, as well as awareness and education programs, in order to reduce environmental contamination in public places.(AU)


No Brasil, cães e gatos têm livre acesso em áreas públicas em algumas cidades, como praças, parques e praias, apesar de leis restritivas para sua permanência nestes locais. Animais infectados por parasitos intestinais contaminam o meio ambiente por meio de suas fezes. O presente estudo teve como objetivo verificar a ocorrência de ovos de helmintos, oocistos e cistos de protozoários em amostras de fezes de três praias da Grande Florianópolis, Santa Catarina, Brasil, no período de março de 2017 a abril de 2018. As amostras de fezes foram processadas pela técnica de flutuação de Willis-Mollay e pela técnica de sedimentação de Hoffman. O percentual de 47,65% de amostras positivas para helmintos ou protozoários foi encontrado nas praias do sul da ilha de Florianópolis, na praia do Morro das Pedras a ocorrência foi de 52,78% e na do Campeche 42,86%. Na praia da Pinheira, em Palhoça, 56,66% das amostras estavam contaminadas com um ou mais parasitos zoonóticos. Os parasitos de maior ocorrência nas três praias analisadas foram os ancilostomídeos e Trichuris vulpis, seguidos de Giardia spp. e Cystoisospora spp. Amostras contendo ovos de To x o c a r a spp. foram colhidas na praia da Pinheira. Conclui-se que a contaminação das praias do presente estudo constitui um problema de saúde pública, tendo em vista à possibilidade de transmissão de zoonoses. Deve ser ressaltada a importância da implantação de programas sanitários para o controle de parasitas de cães e gatos e programas de conscientização e educação, a fim de reduzir a contaminação ambiental em locais públicos.(AU)

ABSTRACT

Mammomonogamus laryngeus (sin.: Syngamus laryngeus) is a nematode which parasites the respiratory tract of some animals. It is occasionally seen in humans, who present symptoms similar to other diseases with respiratory manifestations, such as a chronic dry cough and chest pain, in addition to a "foreign body" sensation in the throat. It can be diagnosed through rhinolaryngoscopy or bronchoscopy examinations, but this often occurs only after spontaneous expectoration of the worms, a long period of symptomatology and the use of several types of medication. In this report, we describe a case of syngamosis in Florianópolis (Santa Catarina, Brazil). The patient consulted several health professionals during the course of the disease and was prescribed numerous drugs. Diagnosis was eventually reached after the spontaneous expectoration of a nematode couple

ABSTRACT

Helminths and protozoa are examples of endoparasites that, during their biological cycles, can alternate between free-life stages and parasitic stages in the environment. Pets, such as dogs and cats, live together with men and play an important role in the society; however, these animals may carry a large number of parasites which, besides showing direct pathogenicity to the host, represent risks to the human health, as is the case of parasitic zoonoses. Public areas like parks, gardens, squares and beaches may offer risks to human users since these environments may contain feces deposited by parasitized dogs. The present study verified the occurrence of helminth eggs and/or protozoan cysts or oocysts in fecal samples collected from sand strips at the beaches Armação do Pântano do Sul, Campeche and Morro das Pedras, in the south of Florianópolis Island, Santa Catarina State (SC), during the summer period. Pet feces were collected in the 2016/2017 summer season, from December 2016 to February 2017. In the Laboratory of Animal Parasitology (CCA-UFSC), fecal samples were processed based on Willis-Mollay flotation technique and Hoffman sedimentation technique. Samples from all three analyzed beaches were positive for the presence of parasites and fecal material was found along the seashore, sites where people walk freely and barefoot. Of 104 fecal samples collected, 45 (43.27%) were positive for one or more parasites. The greatest prevalence was found in Campeche Beach, which had 72.22% positive samples. Ancylostomids were most prevalent, indicating that cutaneous larva migrans is likely to occur in humans. Other parasites such as Trichuris vulpis, Toxocara spp. and Giardia spp. were also detected in coproparasitological analyses. Based on the results, it was concluded that contamination of the beaches in Florianópolis Island, SC, constitutes a public health problem due to the possibility of zoonosis transmission. These results reinforce the importance of establishing health programs for parasite control and educational programs for elucidating the risks of transmission of these zoonoses to the population, as an attempt to reduce environmental contamination risks at beaches of seaside resorts.(AU)


Helmintos e protozoários são exemplos de endoparasitas que, durante seus ciclos biológicos, podem alternar fases de vida livre e de vida parasitária no ambiente. Animais de companhia, como cães e gatos, possuem convívio direto com o homem e desempenham importante papel na sociedade, porém estes animais podem possuir muitos parasitas próprios que, além da patogenicidade direta ao hospedeiro, representam riscos à saúde humana, no caso das zoonoses parasitárias. A utilização de áreas públicas como parques, jardins, praças e praias por estes animais, pode oferecer riscos aos seus frequentadores humanos, uma vez que pode ocorrer a deposição de fezes nesses ambientes por cães parasitados. O presente estudo investigou a ocorrência de ovos de helmintos e/ou cistos ou oocistos de protozoários em amostras de fezes coletadas nas faixas de areia das praias da Armação do Pântano do Sul, Campeche e Morro das Pedras, no sul da ilha de Florianópolis, Estado de Santa Cararina-SC, Brasil, durante o período de verão. As coletas de amostras de fezes de animais domésticos foram realizadas na temporada de verão 2016/2017, a partir de dezembro de 2016 até fevereiro de 2017. No Laboratório de Parasitologia Animal (CCA-UFSC), as amostras de fezes foram processadas pela técnica de flutuação de Willis-Mollay e pela técnica de sedimentação de Hoffman. Amostras colhidas nas três praias analisadas mostraram-se positivas para a presença de parasitos. Material fecal foi observado ao longo de toda orla, locais em que as pessoas caminham livremente e sem calçados. De um total de 104 amostras de fezes coletadas nas praias, 45 (43,27%) estavam positivas a um ou mais parasitas. A praia do Campeche foi a que apresentou maior prevalência, com 72,22% de amostras positivas. Os ancilostomídeos, responsáveis pela larva migrans cutânea em humanos, foram os mais prevalentes. Outros parasitas como Trichuris vulpis, Toxocara spp. e Giardia spp. também foram detectados nas análises coproparasitológicas. Com base nos resultados obtidos, concluímos que a contaminação das praias na Ilha de Florianópolis, SC, constitui um problema de saúde pública, devido à possibilidade de transmissão de zoonoses. Estes resultados reforçam a importância da implantação de programas sanitários de controle de parasitas e programas de educação, esclarecendo os riscos de transmissão destas zoonoses à população, a fim de reduzir os riscos de contaminação ambiental nas praias de balneários.(AU)

ABSTRACT

The survival of infective larvae (L3) of Trichostrongylus colubriformis was evaluated on Brachiaria, Coast-cross and Aruana forage grasses. Feces of sheep parasitized exclusively by T. colubriformis were deposited in winter and spring on experimental plots whose grasses were cut at two heights: 5 cm and 30 cm. One, two, four, eight, 12 and 16 weeks after depositing the feces, fecal and forage samples were collected for the retrieval and quantification of L3. Retrieval of L3 from feces and forage was negligible in winter due to the dry weather, although a few larvae were retrieved in the last larval collections. However, L3 retrieval from fecal samples was greater in spring, especially two weeks after feces were deposited on 30 cm high grasses. At this time, the L3 retrieval rate from the three forage grasses differed significantly (P <0.05), with Aruana grass showing the highest average L3 retrieval rate, followed by Coast-cross and Brachiaria. In conclusion, the winter drought proved very unfavorable for the presence of L3 in the environment, and the microclimate of Aruana pastureland was generally the most favorable for the retrieval of infective larvae.


A sobrevivência de larvas infectantes (L3) de Trichostrongylus colubriformis foi avaliada em pastagem de Braquiária, Coast-cross e Aruana. Fezes de ovinos parasitados exclusivamente por T. colubriformis foram depositadas no inverno e na primavera em parcelas experimentais com duas alturas de corte da forragem, 5 cm e 30 cm. Uma, duas, quatro, oito, 12 e 16 semanas após o depósito, amostras de fezes e de forragem foram coletadas para a recuperação e quantificação de L3. Devido à seca no inverno, a recuperação de L3 das fezes e da forragem foi ínfima, embora tenha havido recuperação de algumas larvas nas últimas coletas. Por outro lado, na primavera houve maior recuperação de L3 das amostras, especialmente duas semanas após a deposição das fezes em meio às pastagens com 30 cm de altura. Nesse momento, houve diferença significativa (P<0,05) entre as três forrageiras, com maior média de L3 no capim Aruana, seguido de Coast-cross e Braquiária. Em conclusão, a seca registrada no período de inverno se mostrou bastante desfavorável à presença de L3 no ambiente e, de forma geral, o microclima da pastagem de Aruana foi o que mais favoreceu a recuperação de larvas infectantes.

ABSTRACT

This experiment aimed to assess the recovery of infective larvae (L3) of Trichostrongylus colubriformis from Brachiaria decumbens cv. Australiana, Cynodon dactylon cv. Coast-cross and Panicum maximum cv. Aruana. The experimental module comprised six plots, with two plots per herbage species. Larval survival was assessed from autumn to winter, under the effect of two herbage-paring heights (5 and 30 cm). TThe paring was carried out immediately before contamination with faces containing T. colubriformis eggs. The feces and herbage were collected at one, two, four, eight, 12 and 16 weeks after feces had been deposited in the experimental plots. In general, larvae were recovered from both herbage and feces until the 16th week. The longer persistence of these larvae in the environment was probably due to warmer temperatures. The number of L3 recovered from the pasture was not influenced by the height of plants, except for Brachiaria and Aruana herbage in the fourth week. Regarding the concentrations of larvae per kg of dry matter (L3/kg DM), recovery was higher from low pasture in all three herbage species. During the autumn, the development and survival of the T. colubriformis free-living stages were not affected by the different herbage species.(AU)


O experimento teve como objetivo avaliar a recuperação de larvas infectantes (L3) de Trichostrongylus colubriformis em Brachiaria decumbens cv. Australiana, Cynodon dactylon cv. Coast-cross e Panicum maximum cv. Aruana. Foram utilizados módulos experimentais constituídos por seis canteiros, perfazendo dois canteiros por espécie forrageira. A sobrevivência larval foi avaliada do outono até o inverno, sob o efeito de duas alturas de poda (5 e 30 cm). A poda foi realizada imediatamente antes da deposição das fezes contaminadas com ovos de T. colubriformis. A colheita das fezes e da forragem foi realizada uma, duas, quatro, oito, 12 e 16 semanas após a deposição das fezes nos canteiros experimentais. De modo geral, foram recuperadas larvas das forragens e das fezes até a 16ª semana. Essas larvas persistiram por mais tempo no ambiente, provavelmente em razão das temperaturas mais amenas. O número de L3 recuperadas nas pastagens não foi influenciado pela altura das plantas, exceto nos capins braquiária e aruana na quarta semana. Já em relação às concentrações de larvas (L3/kg MS) recuperadas das três forrageiras, houve maior concentração nas pastagens baixas. Durante o outono, o desenvolvimento e a sobrevivência de estádios de vida livre de T. colubriformis não foram afetados pelos diferentes tipos de espécies de forrageiras.(AU)

ABSTRACT

T cells produce cytokines that affect host response to infection. This paper reports real-time RT-PCR conditions and validation steps for accurate quantification of Bos indicus cytokines, interleukin (IL)-2, IL-4, IL-8, IL12p-35, IL-13, tumoral necrosis factor (TNF)-alpha, interferon (IFN)-gamma, monocyte chemoattractant proteins (MCP)-1 and MCP-2, and the glycoprotein mucin (MUC)-1 in two groups of Nelore cattle, one resistant and the other susceptible to gastrointestinal nematode infections. RPL-19 was shown to be an ideal internal control gene, since its expression was constant across treatments and presented lower variation when compared to the GAPDH gene. The optimized conditions established in the present study can be used to determine the immune response of cattle under different experimental conditions, such as viral, bacterial and parasite infections.

ABSTRACT

Este estudo teve como objetivos padronizar o kit TF-Test para a quantificação de ovos de parasitas gastrintestinais de ovinos e compará-lo ao método de Gordon & Whitlock modificado (G&W). Vinte quatro cordeiros confinados foram infectados artificialmente com Haemonchus contortus, durante 12 semanas, até o abate, quando foram colhidas amostras fecais e realizada a identificação e contagem dos parasitas abomasais. Nestes animais, ovos de H. contortus foram detectados em 95,8% das amostras fecais por ambos os testes (P>0,05). Os coeficientes de correlação (r) entre a carga parasitária (CP) e os valores de OPG obtidos pelos métodos de G&W e TF-Test foram, respectivamente, de r=0,52 e r=0,51 (dados não transformados) e r=0,85 e r=0,87 (dados transformados em log). Outras 100 amostras fecais foram colhidas de ovinos naturalmente infectados. Nas amostras destes animais, os testes G&W e TF-Test propiciaram o diagnóstico de ovos de estrongilídeos em 85% e 86% das amostras, respectivamente (P>0,05). Pelo TF-Test e pelo G&W, oocistos de Eimeria foram detectados em 33% e em 12% das amostras (P<0,001) e ovos de Strongyloides spp. em 15% e 5% das amostras, respectivamente (P<0,05). Ambos os testes foram precisos para o diagnóstico de estrongilídeos gastrintestinais, porém, o TF-Test foi superior para o diagnóstico de oocistos de Eimeria spp. e de ovos de Strongyloides spp., mas, por outro lado, subestimou o número de ovos de estrongilídeos presente nas amostras.


This study was performed to standardize parasite egg counting in feces of sheep by TF- Test, in addition to compare this test to the Gordon & Whitlock technique (G&W). Twenty-four lambs were artificially infected with Haemonchus contortus throughout 12 weeks. At the end of this time, faecal samples were taken and animals were slaughtered for worm identification and counting. G&W and TF-Test methods were carried out on each fecal sample. Both tests showed Haemonchus eggs in 95.8% of the samples (P>0.05). The corre1ation coefficients (r) between fecal egg counts (FEC) using G&W x Total Worm Count (TWC) were r=0.52 (not transformed data) and r=0.85 (transformed data); between FEC by TF-Test x TWC were r=0.51 (not transformed data) and r=0.87 (transformed data). Other 100 fecal samples were taken from naturally infected sheep. In these animals, the G&W and TF-Test methods showed 85% and 86% of fecal samples positive for Strongylidea eggs, respectively (P>0.05). Also in those animals, Eimeria oocysts were found in 33% of fecal samples by TF-Test, whereas in the G&W only 12% were positive (P<0.001). For Strongyloides spp., TF-Test showed 15% of positive fecal samples, whereas G&W showed 5% (P<0.05). In conclusion, both methods were efficient to diagnose gastrointestinal nematodes and TF-Test was superior to diagnose oocysts of Eimeria spp. and eggs of Strongyloides spp; conversely, Strongylidea eggs counting using TF-Test was underestimated.
