Snail transmitters of schistosomiasis and other mollusks of medical and economic importance at the Simplício Queda Única Hydroelectric Plant, Southeast Brazil.

INTRODUCTION

This paper presents the results of an extensive survey of freshwater mollusks in the Simplício Queda Única Hydroelectric Development area, Southeast Brazil.

METHODS

Mollusks were collected between 2008 and 2013. All specimens were examined for the presence of larval trematodes.

RESULTS

In total, 12,507 specimens classified into 16 genera were obtained. Known snail vectors of schistosomiasis and fascioliasis and exotic species were identified, and new records are reported.

CONCLUSIONS

No specimens parasitized by larval trematodes of medical interest were detected. However, the results reinforce the importance of surveillance in study areas vulnerable to the occurrence of schistosomiasis transmission.
