ABSTRACT The objective of this study was to compare the histopathological aspects of the liver of free-living and farmed bullfrogs (Lithobates catesbeianus). Thirty liver samples were collected from young and adult bullfrogs in the states of Minas Gerais and Rio de Janeiro, Brazil. Marked blood congestion and even hemorrhage and a large number of melanomacrophages were observed in most of the livers from free-living bullfrogs. Additionally, hepatocytes showed cytoplasmic eosinophilia and some showed nuclear hypertrophy and presence of microvesicular steatosis; […]

Necropsy and histological examination were made on bullfrog (Rana catesbeiana) tadpoles fed commercial rations with 32, 36, 45 or 55% crude protein (CP) to establish the relationship between dietary crude protein and health of the animal. In the necropsy, the tadpoles did not show externally any changes, however, the liver of animals at all crude protein levels, presented a straw color and stained. Histological analysis showed livers with rarefaction and degeneration of cell protein, intestines, with colitis and flattening of […]
