Autochthonous transmission of the Indomalayan parasite, Transversotrema patialense, in the Caribbean: Molecular, morphological, and experimental evidence.

The Asian freshwater snail Melanoides tuberculata has been established since the 1960s in the Americas, where it transmits cercariae of a small number of digenetic trematode species from its native range. In 2021-2022, 24 M. tuberculata were discovered shedding transversotrematid cercariae in Puerto Rico, where parasites of this snail have not been previously studied.
