COCCIDIOSE HEPATICA EM Aspistor quadriscutis, Valenciennes, 1840 (TELEOSTEI: ARIIDAE) CAPTURADOS NO ESTUÁRIO DO NORDESTE PARAENSE, AMAZÔNIA, BRASIL.

Abstract: A qualidade do pescado é um fator limitante para a não proliferação de patologias para o ser humano, existindo atualmente vários agentes patogênicos. O gênero Calyptospora abarca uma variedade de formas patogênicas e parasitárias que podem incidir em peixes, aves e moluscos bivalves. Durante esse estudo foram coletados 38 espécimes de Aspistor quadriscutis (bagre ou bagrebranco) no estuário do município de São Caetano de Odivelas, na microrregião do Salgado. Os peixes foram capturados, transportados ao Laborat… Show more

“…The histopathological examination revealed oocyst clusters in the liver parenchyma adjacent to blood vessels. This is a typical histopathological finding of Calyptospora and has been described in several studies (Békési & Molnár, 1991;Ramos et al, 2018;Velasco et al, 2012;Santiago et al, 2012). However, minor variations occur, with some species showing tropism only in blood vessels, as observed in C. gonzaguensis, or only in the liver parenchyma, such as C. paranaidji (Silva et al, 2020;Da Silva et al, 2019).…”

“…Similar results were found in this study. Inflammatory infiltrate and the presence of mononuclear cells surrounding the oocysts were also described by Velasco et al (2012), Ramos et al (2018) and Santiago et al (2012). Melanomacrophages were also found close to oocysts.…”
