Abstract

This study aimed to evaluate the infection by the Austrodiplostomum compactum (Lutz, 1928) metacercariae in the eyes of Geophagus proximus Castelnau, 1855 from the Nova
Avanhandava Reservoir, medium Tietê river, municipality of Buritama, São Paulo State,
Brazil. The parasites were collected from vitreous humor, fixed in AFA solution under cover
slip pressure, stained with carmine and cleared with creosote. The morphometric analysis was performed using a computerized system for analysis of images QWin Lite 2.5 (Leica). Fourtyone G. proximus specimens were collected and 38 were infected in the humor vitreous with A. compactum metacercariae (prevalence = 97%). Four hundred eighty six metacercariae were recovered, range from 1 to 194 in the studied specimens. The mean intensity of infection and abundance were 12.8 ± 5.1 and 11.8 ± 4.75, respectively.
