The aim of this study was to investigate the influence of temperature on the development of Schistosoma mansoni
infections in Biomphalaria glabrata
. The snails were infected at 15, 20, and 30°C, and the cercarial release was analyzed after 30 and 60 days post-infection. Our results showed that a decrease in the temperature has a substantial influence on the development of S. mansoni
infection in B. glabrata
, with significant differences (p < 0.05) between 15 and 30°C. These data could provide a better understanding of the epidemiological aspects of schistosomiasis.
