The aim of this study was to identify and describe intestinal lesions caused by helminths in red-footed tortoise (Chelonoidis carbonarius) and yellow-footed tortoise (Chelonoidis denticulatus) reared in captivity in the Zoo and Botanical Park of Teresina, Piauí State, Brazil. The parasitological evaluation of 142 of these tortoises revealed that all were parasitized by helminths (ascarids and strongyles), which were identified as Atractis thapari and Chapiniella variabilis by light and electron microscopy. The 12 most parasitized tortoises (six per species) were euthanized, and samples of small and large intestine were evaluated by histopathology. Macroscopically, all small and large intestines had hyperaemia. Microscopically, hyperaemia (12/12), diffuse goblet cell hyperplasia (8/12) and submucosa oedema (1/12) were observed in the small intestine. Hyperaemia was observed in the large ...

El estudio tuvo como objetivo identificar y describir lesiones intestinales ocasionadas por helmintos en jabutis (Chelonoidis carbonarius y Chelonoidis denticulatus) criados en cautiverio en el Parque Zoobotánico de Teresina, estado de Piauí, Brasil. La evaluación parasitológica de 142 de estas tortugas reveló que todas estaban parasitados por helmintos (ascarídeos y estrongilideos), que fueron identificados como Atractis thapari y Chapiniella variabilis por medio de microscopio de luz y microscopio electrónico. Los 12 animales más parasitados (seis de cada especie) fueron eutanasiados y muestras de intestino delgado y grueso fueron evaluadas por histopatología. Macroscópicamente, todos los intestinos, tanto delgado como grueso, presentaban hiperemia. Microscópicamente, en el intestino delgado se observó hiperemia (12/12), hiperplasia difusa de células caliciformes (8/12) y ...
