Detection of Mycobacterium avium in pet birds

the present study is a report on the presence of mycobacterium avium in four birds of the psittaciform order kept as pets. anatomopathological diagnosis showed lesions suggestive of the agent and presence of alcohol-acid resistant bacilli (aarb) shown by the ziehl-neelsen staining. the identification of mycobacterium avium was performed by means of pra (pcr restriction analysis). dna was directly extracted from tissue of the lesions and blocked in paraffin. the role of this agent in pet bird infection is discussed, as well as its zoonotic potential.
