Resumo: Continuing epidemiologic studies of the gastrointestinal nematodiosis of Zebu calves in the Pantanal Mato-grossense region, Brazil, the authors studied the natural population of adult nematodes in weaning calves in the Paiaguás subregion during two years, by using monthly faecal egg counts and necropsies. The identified species, intensity and seasonality of infection were discussed in relation to previous results observed in the Nhecolândia subregion. It was verified that flooding of native pastures during certain period in the wet season inhibits development and/or transmission of the infective larvae to calves. Simultaneous grazing of adult with young animals apparently reduced the infection in the young ones. A higher number of immature forms (L4) was found during the dry season, showing an escape mechanism from the adverse environment. Through parallel observations it was concluded that gastrointestinal nematodiosis can assume serious character in the Pantanal region.

As espécies encontradas, a intensidade e a distribuição estacional das infecções foram discutidas em relação aos resultados obtidos em trabalhos anteriores realizados na sub-região da Nhecolândia. Verificou-se que o alagamento das pastagens, durante certo período da estação chuvosa, inibe o desenvolvimento e/ou transmissão das larvas infectantes para o hospedeiro. O pastejo simultâneo de animais adultos com animais jovens parece diminuir a infecção nestes últimos. Durante a estação seca, foi encontrado um número maior de formas imaturas (L4), evidenciando um mecanismo de proteção dos parasitas contra o meio adverso, nesse período. Por observações paralelas ao experimento, pode-se concluir que as nematodioses gastrintestinais podem assumir caráter grave na região do Pantanal Mato-grossense.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCatto, João BatistaFurlong, John2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15474Pesquisa Agropecuaria Brasileira; v.18, n.11, nov. 1983; 1265-1271Pesquisa Agropecuária Brasileira; v.18, n.11, nov. 1983; 1265-12711678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15474/9414info:eu-repo/semantics/openAccess2014-04-16T18:43:24Zoai:ojs.seer.sct.embrapa.br:article/15474Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:43:24Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
