Resumo: | ABSTRACT The use of organophosphates has been recommended for fish, especially the trichlorfon to control parasites. Colossoma macropomum were exposed to trichlorfon during 96 hours and of total number of mucous cells decreased in the number of cells when compared to the control group. Glycoproteins acid, acid sulphated and neutral was identified in the gill epithelium. Neutra glycoprotein had a significant decrease between control and the sublethal concentration. Acid glycoprotein didn’t have any significant difference between the groups exposed to the trichlorfon, compared to the control group. Sulfated acidic glycoprotein in the group exposed to the trichlorfon was noticed a reduction in number of mucosal cells acidic sulphated. The differences between density cell and production glycoprotein was a response of these cells after exposure to xenobiotic. The reduction of neutral, acid and sulphated acid glycoprotein in the MC of the gill epithelium Colossoma macropomum may affect gills epithelial surface protection by reducing the formation of an unstirred layer and enhance the ion loss.
