Ithyoclinostomum dimorphum Diesing, 1850 (Digenea, Clinostomidae) in Hoplias malabaricus (Erythrinidae) with the first report of infection of the eyes.
The present study investigated the occurrence of metacercariae of Ithyoclinostomum dimorphum in Hoplias malabaricus in the basin of the São Francisco River in the state of Minas Gerais (Brazil). Twenty-nine fi sh were examined in June 2012 during a survey of fi sh and parasitic fauna. Of the fish examined, 34.5 % had infected eyes, intestine and musculature, with a mean intensity of 1.1 and an abundance of 0.4 per fi sh. The prevalence in the intestine was 31.0 %, with mean intensity of 1.1 and mean abundance of 0.3. In the eyes, the prevalence was 3.4 %, with a mean intensity of 1.0 and mean abundance of 1.0. The metacercaria found in the right eyeball was lodged between the cornea and iris. The low parasitism did not affect the condition factor (Kn) of the parasitized fi sh. This was the fi rst report of I. dimorphum in the eyes of Hoplias malabaricus, a secondary intermediate host for this endoparasite.
