Histological evaluation of bursal recovery of chickens after vvIBDV-mono-inoculation and C.jejuni coinoculation (Exp. B as a representative experiment). Representative bursa sections of control (a), C. jejuni- (b), vvIBDV- (b), and vvIBDV + C. jejuni coinoculated (d) chickens at 21 days pbi. Arrows indicate recovering follicles B. e A summary of bursal recovery in the BF of chickens at different time points (Exp. A and Exp. B are separated by a dotted line) Error bar indicates the standard deviation (SD), *indicates significant differences between the two indicated groups at the indicated time point (P < 0.05, n = 6/group). pbi post bacterial inoculation; pvi post IBDV (virus) inoculation
