“…Mycobacterium avium subsp. avium causes a chronic infection in several species of birds that is characterized by granuloma formation in various organs (Kutsal and Saglam, 1988;Butcher et al, 1990;Shane et al, 1993;Singbeil et al, 1993;Sanford et al, 1994;Sato et al, 1996;Thoen, 1997;Doneley et al, 1999;Marco et al, 2000;Gonzalez et al, 2002). The frequency of the disease in pheasants (Phasianus colchicus) is unclear due partially to the limited number of reports (Hejlicek and Treml, 1993;Singbeil et al, 1993;Hejlicek and Treml, 1995b).…”

Avian tuberculosis was diagnosed histopathologically and microbiologically in two pheasants (Phasianus colchicus) and two peafowl (Pavo cristatus) kept in the same aviary. The incidence of avian tuberculosis in the aviary was 6%. Non-mineralized caseogranulomas were present in the liver (3 cases), spleen (3 cases), intestine (2 cases), lung (2 cases), and cloaca (1 case). Granulomas in the lung were present only in peafowl. The presence of granulomas in the lung of both infected peafowl suggests that peafowl were exposed to the agent via the respiratory route rather than the alimentary route. Histopathologic findings were typical of avian tuberculosis, including acid fast bacilli and centrally located caseo-necrosis surrounded by epitheloid macrophages, lymphocytes, and multinucleated giant cells. Mycobacterium avium subsp. avium was isolated from tissue samples of all infected birds.

“…This agreed with previous observations obtained with ducks and some other bird species kept in zoological gardens (Cowan, 1968a,b). There is, however, a case report (Sato et al, 1996) describing one out of two Hooded Merganser (Lophodytes cuculatus) imported to Japan succumbing to tuberculosis associated with amyloid deposits. No further details were given.…”

Amyloid A amyloidosis in non-infected and avian leukosis virus-C persistently infected inbred ducks

et al. 2001

The breeding history of the first inbred strain of Khaki Campbell ducks is presented. The genetic homogeneity of this strain was tested on the basis of serum amyloid A (SAA) polymorphism and it was established that it harbours only the SAA allele A, which is expressed in liver, lung and bursa of Fabricius tissues. Pathogenic changes in control and avian leukosis virus-C (ALV-C) persistently infected ducks were evaluated during the period spanning 1 to 10 months after hatching. In both groups, AA amyloidosis was revealed and characterized. In spite of the inbred nature of animals, the incidence of amyloid A deposition varied among experiments, suggesting that additional non-genetic factors are involved. Similar variation was found in ALV-C persistently infected ducks, where only in one out of three experiments was the incidence of AA amyloidosis significantly higher than in controls.
