Peafowl (Pavo cristatus), similarly to other Galliformes, are particularly susceptible to infection by Mycobacterium avium. Peafowl differ from other Galliformes in the clinical image of the infection, with dominating respiratory signs. Occurrence of severe and sustained dyspnoea in peafowl raises suspicion of mycobacteriosis, which, however, is not always easy to confirm. In the cases described here, mycobacteria were detected in direct swabs from the trachea of two individuals, and cultures were conducted on the Löwenstein-Jensen medium. In one individual, no mycobacteria were found in tracheal swabs stained by the Ziehl-Neelsen method, despite the presence of clear clinical signs. The fourth case was a young bird submitted for necropsy. The cause of death was a mechanical trauma, but scarce caseous nodules typical of mycobacteriosis were found in the liver, spleen and lungs. The Mycobacterium avium isolates obtained from those cases were compared using (CCG)4-based PCR. A high similarity of three isolates of Mycobacterium avium subsp. avium was observed, two of which were derived from peafowl originating from the same farm, while the isolate from the fourth bird differed significantly and was identified by sequencing as Mycobacterium avium subsp. paratuberculosis.

Gallibacterium spp. is a new genus of the family Pasteurellaceae. These Gram-negative rods are a part of the physiological flora of the upper respiratory tract, genital tract and gastrointestinal tract of birds and have been found in different species of domestic and wild birds. They are opportunistic pathogens that were isolated from birds with pathological lesions or conditions. This paper presents the first case of Gallibacterium anatis isolation from peacocks with respiratory tract infections. Three isolates from lung tissue were identified on the basis of phenotypic properties as Gallibacterium anatis biovar Haemolytica. The whole flock of peacocks was isolated in a small closed farm building for 5 weeks. During this period the first clinical signs of the disease were observed. That situation could result in immunosuppression in birds, which is one of the predisposing factors of opportunistic G. anatis infections. This observation confirms the important role of the stress factor in an infection caused by these bacteria.
