Immune organ indices in the chicken inoculated with different pathogenic combinations. The thymus index of birds inoculated with the C. psittaci + ORT/A. fumigatus group was substantially different compared to the H9N2/A. fumigatus or control group (**P < 0.01). However, no significant difference was found among the C. psittaci + H9N2 + ORT/A. fumigatus, C. psittaci + H9N2/A. fumigatus and C. psittaci + ORT/A. fumigatus groups on the same time points. Furthermore, the spleen index of chickens infected with the C. psittaci/A. fumigatus group was substantially different as compared to the H9N2/A. fumigatus (*P < 0.05), ORT/A. fumigatus, A. fumigatus or control (**P < 0.01) group on day 5 p.i. On day 10, a significant decrease was recorded in the C. psittaci + H9N2 + ORT/A. fumigatus, C. psittaci + ORT/A. fumigatus, C. psittaci + H9N2/A. fumigatus or C. psittaci/A. fumigatus groups in comparison with the H9N2/A. fumigatus or control group (**P < 0.01). Regarding the bursal index, a significant decrease was obvious in the C. psittaci + H9N2 + ORT/A. fumigatus, C. psittaci + ORT/A. fumigatus or C. psittaci + H9N2/A. fumigatus group in comparison with the H9N2/A. fumigatus or control group (**P < 0.01) on day 10 p.i.
