Their livers were removed and processed for light microscopy. Overall, 90% of the specimens presented some degree of steatosis of the liver, which was invariably associated with the presence of Microsporidium sp. The present study confirms the occurrence of steatosis in G. grahamae associated with parasitic infections by Microsporidium. The findings indicate that the condition of otherwise healthy fishes in their natural environment may be affected negatively by parasites.engAcesso AbertoPeixePeixe teleósteoGobioides grahamaeFígado gordurosoEsteatoseIlha de Marajó - PASalvaterra - PAPará - EstadoAmazônia brasileiraArtigo de Periódico
