First record of Trichodina centrostrigeata Basson, Van As & Paperna, 1983 (Ciliophora: Trichodinidae) from Oreochromis niloticus (Linnaeus, 1758) cultured in southeastern Mexico

First record of Trichodina centrostrigeata Basson, Van As & Paperna, 1983 (Ciliophora: Trichodinidae) from Oreochromis niloticus (Linnaeus, 1758) cultured in southeastern Mexico

ABSTRACT Nile tilapia Oreochromis niloticus is one of the most economically important freshwater fish cultivated worldwide. Despite its importance and being one of the cichlid fish most studied from a parasitological point of view in Mexico, there are few studies about the ectoparasite protozoa that...

Despite its importance and being one of the cichlid fish most studied from a parasitological point of view in Mexico, there are few studies about the ectoparasite protozoa that infect them. In this study, a total of 240 juvenile individuals of O. niloticus from an experimental culture (in Tabasco, Mexico) were examined to detect the presence of trichodinid parasites. Trichodinid parasites were impregnated with silver nitrate and stained with Harris’ hematoxylin solution for taxonomic evaluation. A disc-shaped trichodinid with a body diameter of 38 ± 3.3 μm adhesive disc diameter of 34 ± 3.3 μm and a denticulate ring diameter of 19 ± 2.1 μm was found. Trichodina centrostrigeata has been previously reported having specificity for cypriniform species, but in the present study, the Nile tilapia was reported as a new fish host and southeastern Mexico as a new geographical distribution for this parasite.info:eu-repo/semantics/openAccessPontificia Universidad Católica de Valparaíso.
