چکیده
Infectious bursal disease (IBD) is an immunosuppressive disease of chickens. The mechanism of tolerance in turkeys and ducks is not yet deciphered. This study investigated the pathogenesis of IBD in chickens, turkeys and ducks by assessing the severity of oxidative stress and antioxidant response in infected birds. Forty chicks and 35 turkey poults and ducklings at 4 weeks were separated into two groups/bird species (A and B), i.e., chickens, CA and CB; turkeys, TA and TB; and ducks, DA and DB. Each bird in group A was inoculated with 1LD50 IBD virus, while group B served as control. Infected birds were bled, and liver, kidney, and bursa of Fabricius (BF) were harvested at 5 days post-infection and assayed for MDA, H2O2, NO, MPO, GSH, GPx, SOD and GST using standard methods. Results indicated that MDA level (µmol/mg protein) was higher in liver (13.11 ± 1.77) and kidney (11.10 ± 0.16) of CA than in DA (2.74 ± 0.01; 7.62 ± 0.37) and TA (1.42 ± 0.09; 6.79 ± 0.27). H2O2 level (µmol/min/mg protein) in BF of CA (49.10 ± 3.99) was higher than DA (35.89 ± 1.54) and TA (36.07 ± 2.18). MPO level in CA was higher than in DA and TA. Superoxide dismutase activity (unit/mg protein) in BF of CA (11.56 ± 1.85) was higher than DA (8.59 ± 0.15) and TA (7.00 ± 0.42) and GSH level (µmol/mg protein) was higher in BF of DA and TA (105.81 ± 1.59 and 93.89 ± 7.93) than in CA (92.30 ± 3.12). GPx level (unit/mg protein) was higher in the liver of DA and TA (26.81 ± 2.45 and 30.01 ± 2.18) than CA (24.21 ± 0.94) as well as in BF of TA (92.79 ± 3.38) than in CA and DA (83.63 ± 4.62, 81.85 ± 4.42).  Thus, chickens undergo a higher degree of oxidative stress post-IBD virus infection than ducks and turkeys. Simultaneously, the antioxidant defense system was generally more active in infected ducks and turkeys than in chickens.
