Resumo: | A comparison of the susceptibility between the two species of Lymnaea: L. columella and L. viatrix was performed using the same size of snail and the same degree of infection with miracidia of F. hepatica. It was confirmed that L. viatrix is an intermediate host of F. hepatica possessing higher susceptibility to the infection than L. columella, under laboratory conditions. Moreover it showed a high production rate of redia and metacercariae in L. viatrix. Development stages of F. hepatica in the two species of Lymnaea were also observed and the first appearance of sporocysts was observed six hours after the infection and first redia in the ninth day in both species; mature redia and cercariae in the twentieth day in L. viatrix, and in the twenty-seventh day in L. columella, respectively. Cercarial emergence in the twenty days in L. columella: metacercariae in the thirty-sixth day in both snail species. Presence of daughter redia of F.hepatica was observed on the twentieth day after experimental infection in L. calumella. The viability of metacercariae obtained was confirmed by oral infection to mice. Fasciola eggs wore delected in feces on the thirty-second day after infection. In necropsy, two adults of F.hepatica were colected. |

Cercarial emergence in the twenty days in L. columella: metacercariae in the thirty-sixth day in both snail species. Presence of daughter redia of F.hepatica was observed on the twentieth day after experimental infection in L. calumella. The viability of metacercariae obtained was confirmed by oral infection to mice. Fasciola eggs wore delected in feces on the thirty-second day after infection. In necropsy, two adults of F.hepatica were colected.Comparou-se a suscetibilidade entre as duas espécies do gênero Lymnaea: L. viatrix (Orbigny, 1835) e L. columella(Say, 1817), utilizando-se o mesmo tamanho de moluscos e o mesmo grau de infecção com miracídios de Fasciola hepatica. Comprovou-se que L. viatrix atua como hospedeiro intermediário de F. hepatica, tendo maior suscetibilidade à infecção do que L. columella, em condições laboratoriais. Foram observados esporocistos seis horas após a infecção, em ambas as espécies; rédias imaturas no nono dia, em ambas: rédias maduras e cercárias no 20º dia, em L. viatrix, e no 27º dia, em L. columella: e metacercárias no 36º dia, em ambas as espécies. Evidenciaram-se, de vez em quando, rédias-filhas em L. calumella no 20º dia de infecção. A viabilidade das metacercárias foi comprovada pela infecção de camundongos, por via oral, encontrando-se ovos de F. hepatica nas fezes, no 32º dia de infecção. Nas necropsias foram encontrados dois exemplares de F. hepatica.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMattos, Mary Jane Tweedie deUeno, Hakaru2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15835Pesquisa Agropecuaria Brasileira; v.24, n.5, maio 1989; 615-622Pesquisa Agropecuária Brasileira; v.24, n.5, maio 1989; 615-6221678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15835/9905info:eu-repo/semantics/openAccess2014-08-26T19:35:15Zoai:ojs.seer.sct.embrapa.br:article/15835Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-26T19:35:15Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
