Characterization of Leishmania spp. causing cutaneous leishmaniasis in Manaus, Amazonas, Brazil.

abstract：:In freshwater ecosystems, snails can significantly influence the competition between primary producers through grazing of periphyton. This activity can potentially be modified by trematodes, a large group of parasites which mostly use molluscs as the first intermediate host. Available studies, however, show contradict...
