“…Further, these diffuse histiocytic infiltrations are characteristic of M. genavense infection in birds, and were in accord with previous descriptions (5,16,20,21). Though granulomatous tuberculous lesions with central caseous necrosis and encircled with chronic inflammatory cells and fibrosis are more commonly observed in M. avium infection (22), similar lesions are occasionally observed with M. genavense infection in psittacine birds (19).…”

“…In birds, however, the oral route was considered the primary means of infection (5,6,22,25). The extensive invasion of the pulmonary tissue evident following M. genavense infection in birds suggests a possible airborne transmission (6,16,17,20). Bacteremia associated with M. genavense infection that causes disseminated mycobacteriosis might also be responsible for the prominent involvement of the lungs.…”

“…In birds, M. genavense infection was first reported in 1993 (5). Since then, M. genavense infections have been reported in various avian species including orders of Coraciiformes, Piciformes, Galliformes, Passeriformes, and Psittaciformes (6,16,17,(19)(20)(21). Avian mycobacteriosis lesions caused by M. genavense severely affect the intestine and liver (5,20).…”

Two diamond doves (Geopelia cuneata) in a flock of 23 birds housed in an aviary in a zoo in central Japan were found dead as a result of mycobacteriosis. Fecal samples of the remaining doves were positive for mycobacterial infection, and thus they were euthanatized. Clinical signs and gross pathology, including weight loss and sudden death and slight enlargement of the liver and intestine, were observed in a small number of birds (3/23). Disseminated histiocytic infiltration of either aggregates or sheets of epithelioid cells containing acid-fast bacilli, in the absence of caseous necrosis, were observed in different organs of the infected doves, especially lungs (23/23), intestines (9/23), livers (7/23), and hearts (6/23). Mycobacterium sp. was isolated from the livers of three birds (3/23). DNA extracted from frozen liver and formalin-fixed, paraffin-embedded tissues (5/23) were used for amplification of the gene encoding mycobacterial 65-kDa heat shock protein (hsp65). The causative Mycobacterium species was identified by PCR-restriction fragment length polymorphism analysis. Mycobacterium genavense infection was confirmed in three of the diamond doves. Moreover, partial 16S rDNA gene sequencing revealed 100% identity across the three samples tested, and 99.77% nucleotide homology of the isolate sequence to M. genavense. The main route of M. genavense infection in the diamond doves was most likely airborne, suggesting a potential zoonotic risk of airborne transmission between humans and birds.

“…The pathogen has also been detected in birds belonging to the orders Coraciiformes, Piciformes and Galliformes. M. genavense infection is most frequently reported in Amazon parrots and has been described in pet birds in Europe, USA and Australia (Hoop et al, 1993;Antinoff et al, 1996;Kiehn et al, 1996;Portaels et al, 1996;Ramis et al, 1996;Holsboer-Buogo et al, 1997;Tell et al, 2001;Manarolla et al, 2007).…”

ABSTRACT:In 2005 a Mycobacterium genavense infection was diagnosed in one blue-headed parrot (Pionus menstruus) imported from Surinam (South America), the first such incidence in the Czech Republic. The bird died suddenly. Histopathological examination revealed a diffuse granulomatous inflammatory reaction in the intestinal mucosa. Tissue sections of the intestines stained by Ziehl-Neelsen were microscopically positive for acid-fast bacilli. Culture examinations were made by the conventional solid media, the manual BD-BBL MGIT and the automated MGIT 960 liquid culture systems. We have detected mycobacteria by the automated MGIT 960 liquid culture system in the intestinal tissues after 92 days and on solid Herrold's Egg Yolk Medium without Mycobactin J after 270 days. The manual BD-BBL MGIT liquid culture and the conventional culture system revealed mycobacteria after 150 days of cultivation from three and two tissues samples, respectively. M. genavense was identified by HAIN Life Science kits (GmbH, Germany) and was found to be the cause of death for the parrot, which was one of 14 exotic birds kept by its keeper. From the environment M. a. hominissuis was isolated only, which was documented by antibody detection of this member of the M. avium complex in sera samples of five birds. Three two month old common pet parakeets (Melopsittacus undulatus) were for one day in contact with drinking water contaminated by the liver suspension from the infected bird. After 12 months they were euthanized. Subsequent culture was negative for the presence of mycobacteria and histopathological examinations showed no granulomatous inflammatory reaction or any other pathological findings.Keywords: zoonosis; avian tuberculosis; Psittaciformes; granulomatous inflammation; mycobacteriosis List of abbrevations:AFB = acid-fast bacilli; MAA = Mycobacterium avium subsp. avium; MAC = Mycobacterium avium complex; ZN = Ziehl-Neelsen staining

The article presents the results of bacteriological examination of five samples of feces from grey parrots (Psittacus) (n = 3), cockatoo (Cacatua) (n = 1), yellow-crowned amazon (Amazona) (n = 1). Five cultures of mycobacteria were bacteriologically isolated from the five samples. According to biochemical and cultural-morphological characteristics, mycobacterial cultures are classified as Mycobacterium scrofulaceum (n = 1) and Mycobacterium genavense (n = 4). Isolated cultures of mycobacteria are important in human pathology. Infected exotic poultry pose a potential risk of mycobacterial infection in their owners, so it is necessary to conduct research on biological material
