Resumen:
From February 2002 to December 2004, the helminth parasite
fauna and reproductive features of the frog Scinax nasicus were
studied from Corrientes city, Province of Corrientes, Argentina.
The parasite richness was 15 species of helminths (larval
and adult) including trematodes (73%), nematodes (20%) and
acanthocephalans (7%). Opisthogonimus sp. showed the highest
prevalence (41%). The definitive hosts of these larval trematodes
are probably snakes; S. nasicus acts as second intermediate
host, and become infected by direct penetration of cercariae.
The number of mature ova per female ranged from 413 to 3922,
and the mean mature ovum diameter was 0.76 ±0.17mm. This
species has a prolonged reproductive pattern.
