Effects on some blood parameters of GX0101 and GX0101ΔMeq (n = 5). A: Total leucocytes; B: Total lymphocytes; C: Total erythrocytes. At 7, 14, 21, 31 and 42 days p.i., five chickens were randomly selected from each treatment. *P < 0.05 compared with those in control group. The means ± SD at each time point are shown. The number of leukocytes and lymphocytes in peripheral blood progressively increased in chickens infected with bac-GX0101 and GX0101ΔMeq compared with those in control group at days 14 p.i. And chickens displayed anemia with the number of erythrocytes progressively reduced on days 7, 14, 24, 31 and 42 after infection with bac-GX0101.
