Estudo morfológico de microparasitas eucariotos encontrados em Amuré Eleotris aff. pisonis e Jacundá Crenicichla saxatilis coletados no distrito de Outeiro, Belém, Pará, Brasil.

Abstract

The Amazon basin is a location of largest and most diverse fish fauna of the world. Fishes are an important source of protein but are subject to a wide variety of diseases caused by intracellular parasites, that although little studied, affect directly sanity and quality of animal. The practice study of characterize structure parasitological on fish is the most important, in order to verify and determine the dispersion of parasites that cause imbalance in the ecosystems, and allow a general and specific identification, allowing to know even more of parasites. The present work aimed to describe the morphological aspects of microparasites in fish, Eleotris aff. pisonis (Amuré) and Crenicichla saxatilis (Jacundá), originating in district of Outeiro / PA. There were made 5 collections, totaling 50 specimens each. Fish samples were analyzed at the LPCA (Carlos Azevedo Research Laboratory) of University Federal Rural of Amazonia (UFRA). In organs parasitized were removed fragments, fixed and processed for light microscopy. In a morphological analysis were found microparasites belonging to 03 groups, Cnidaria (sub-Filo Myxozoa), Microsporidia and Apicomlexa.
