[Uncommon mycobacterial infections in domestic and zoo animals: four cases with special emphasis on pathology].
Infections caused by classical tubercle bacilli are rare during the last years. Nevertheless, diseases caused by other mycobacteria have to be considered clinically and in diagnostic pathology especially in cases of immunosuppression and due to their potential zoonosis risk. An infection by mycobacteria was diagnosed in four animals (Mayotte Maki, Blue-headed Parrot, Patagonian sealion, Beagle) necropsied between 1995 and 2002 in the Institute of Veterinary-Pathology of the University of Leipzig. The Maki, the blue-headed parrot and the dog showed a disseminated character of the disease caused by Mycobacterium genavense (monkey and bird) resp. Mycobacterium avium (dog), while an open chronical tuberculosis of the lungs due to a pathogenic member of Mycobacterium tuberculosis complex was observed in the seal. All these bacteria are potential causes of zoonoses. So, if granulomatous or disseminated histiocytic alterations are detected in diagnostic pathology, mycobacterial infections should always be included in differential diagnoses and require careful aetiological investigations by histopathological and bacteriological methods.
