Oxidative stress biomarkers are associated with visible clinical signs of a disease in frigatebird nestlings

摘要: Infectious diseases are one of the most common threats for both domestic and wild animals, but little is known about effects on physiological condition survival animals. Here, we have tested first time in a vertebrate facing viral disease possibly due to herpesvirus (i) whether nestlings with either low levels oxidative damage or high antioxidant protection less susceptible develop visible clinical signs, (ii) associated nestlings' status, (iii) association between status similar males females (iv), cloacal tracheal swabs might be used detect herpesvirus. To address our questions, took advantage population Magnificent frigatebirds (Fregata magnificens) whose experienced mortality rates recent times. Our work shows that blood lipid observable signs probabilities nestling frigatebirds, glutathione red cells emergence disease. provides evidence differences underlie individual health survival.
