Abstract: Schistosomiasis is a parasitic disease known as “water belly”, bilharziasis, or snail disease, caused by the trematode Schistosoma mansoni. Firstly, it was seen as a rural endemic, however in recent decades, several urban centers are presenting reports of patients affected by schistosomiasis. The presence of the freshwater snail is an indispensable factor in the occurrence of S. mansoni cycle, as well as the disease sets in. Susceptible species of freshwater snails are Biomphalaria glabrata, B. straminea, and B. tenagophila. By studying the presence of these mollusks and observing whether they are infected, it is possible to determine where the disease came from. Objective: Collect mollusks from water sites at Pains, a city of MG, identify the species and analyze whether they were infected with trematode larvae. Methods: From February 2018 to January 2019, mollusks were collected in three locations, with the aid of a sieve and tweezers. The collected species were taken to the UNIFOR-MG Microscopy laboratory, where they were separated and identified through morphological characteristics, as well as the cercariae that emerged. Conclusion: Studying the malacofauna, it was possible to conclude that in the investigated locations there are mollusks contaminated with S. mansoni larvae, as well as other species of trematode larvae, configuring these places as a public health problem.
