Biomphalaria spp . (Preston, 1910) snails in the municipality of Juiz de Fora, Zona da Mata Mineira mesoregion, State of Minas Gerais, Brazil
This study focuses on the geographic distribution of the snail of the
genus Biomphalaria and evaluates its infectivity by Schistosoma mansoni
in 5264 specimens collected in the municipality of Juiz de Fora,
Minas Gerais, Brazil. Of the 31 locations studied, 6 were reservoirs,
11 rudimentary holding ponds, 7 irrigation ditches, 5 lakes, 1
ornamental pond, and 1 waterfall. Intermediate hosts were found only in
the rudimentary ponds and ditches, which were 100% positive. Using
morphological and molecular analysis techniques, B. tenagophila, B.
peregrina, and B. straminea were identified. This is the first report
of B. stramÃnea in the municipality, and evaluation of its
infective potential revealed susceptibility of 25.4%. Although we did
not find specimens of Biomphalaria infected by S. mansoni, the data
obtained indicate the presence of intermediate hosts, especially in the
irrigation ditches in Juiz de Fora, and their proximity to contaminated
areas
