title: Infectious bursal disease virus and Alcaligenes faecalis infections in turkeys.
abstract: To determine if infectious bursal disease virus (IBDV) augments alcaligenes rhinotracheitis (ART), turkey poults were exposed to IBDV, Alcaligenes faecalis, or both IBDV and A. faecalis. In five experiments, poults exposed to IBDV alone exhibited neither signs of disease nor histopathologic lesions. Serum antibodies to IBDV were detected in poults exposed to this virus by inoculation and by direct contact with inoculated birds. Signs of ART were observed 4 to 6 days following exposure to A. faecalis. Clinical signs of ART and histopathologic lesions in the upper respiratory tract of poults exposed to both IBDV and A. faecalis were similar to those observed in poults exposed to A. faecalis alone.
