  • Descrição: The aim of this study was to analyses nitric oxide, antioxidant status, and oxidative profile in the liver of laying hens naturally infected by serovar Gallinarum ( Gallinarum). The nitrite/nitrate (NO ), reactive oxygen species (ROS), thiobarbituric acid-reactive substances (TBARS), catalase (CAT), glutathione reductase (GR), glutathione peroxidase (GPx) and glutathione S-transferase (GST) activities were measured in liver samples, as well the biomarkers of hepatic function (alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), total protein and albumin levels measured in serum. NO levels and CAT activity were reduced in hepatic tissue of infected hens. On the other hand, TBARS and ROS levels, GR, GPx and GST activities were higher in infected animals. On biomarkers of tissue damage, ALT, AST, GGT and total protein levels were higher in serum of infected hens, and showed decreased albumin levels. In summary, ROS and TBARS production lead to damage on the membrane lipids that alter activities of antioxidant enzymes CAT, GR, GPx and GSH, an adaptive response against Gallinarum infection, contributing to the pathophysiology and clinical signs of the disease.
