Abstract / Zusammenfassung

Avian tuberculosis is a long-lasting, debilitating disease that impacts a wide range of wild and domestic birds. Turkeys are less susceptible to infection than chickens, pheasants and partridges. The primary cause of avian tuberculosis is M. avium subsp. avium serotypes 1, 2 and 3 and genotype IS901 segment and non-specific segment IS1245). Indeed, M. avium is known to cause diseases in swine and other mammals. While humans may contract this disease, the strains found in birds and humans are typically different. Transmission of M. avium occurs through the oral route, resulting in its multiplication in macrophages and the formation of submucosal and serosal granulomas in the intestines. When granulomas become ulcerated, bacteria are released into the intestinal lumen and eventually pass through faeces. Additionally, the bacteria can enter the bloodstream and cause granulomas in visceral organs. Diagnosis is based on the post-mortem lesions and demonstration of the acid-fast bacilli in tissue samples. Treatment is not recommended because of the risk of the emergence of drug-resistant strains.
