Abstract

With the purpose of studying the susceptibility of Lymnaea (pseudosuccinea) columella, from Minas Gerais state in Brazil, to infection by Fasciola hepatica, four samples from different regions in the state of Minas Gerais were tested in comparison with one sample from Rio de Janeiro state and another from Rio Grande do Sul state, using a sample of F. hepatica isolated from sheep in Rio Grande do Sul and maintained in rabbits in laboratory conditions. The Lymnaea were exposed to infections with six, eight and ten miracidia by molusca and studied the occurrence of infection and the deathrate. In this conditions the conclusions were: 1- the deathrate of the Lymnaea (pseudosuccinea) columella seems do not be in relation with the occurrence of infections by Fasciola hepatica; 2- the samples of L. (Pseudosuccinea) columella from Minas Gerais, Rio de Janeiro and Rio Grande do Sul had similar susceptibility to infection by F. hepatica; 3- the Minas Gerais human population and the cattle, sheep and swine herds may be considered in risk of F. hepatica infection, specially those that live in Rio Paraíba valley, by the fact that nowadays F. hepatica infection is common in Rio de Janeiro and São Paulo, Rio Paraíba valley.
