Elevated serum levels of total proteins, albumin/globulin ratio, AST, ALT, urea, urea nitrogen ratio, haptoglobin, and zinc but lower albumin, SOD, and GPx were indicative of cellular leakage, loss of integrity and functionality of the cell membrane in the liver and kidneys, diminished glomerular filtration rate, malnutrition and malabsorption syndrome, and DNA damage, which could be explained by the variation in clinical symptoms and bacterial load between the groups. The gene discussed is SOD1; the disease is malnutrition.
