The effects of temperature change on the infection rate of Biomphalaria glabrata with Schistosoma mansoni.
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 degrees 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 degrees C. These data could provide a better understanding of the epidemiological aspects of schistosomiasis.
