background and objectives: diagnosis of avian tuberculosis by conventional culture method is still considered as the “gold standard” technique. the main objective of this study was to compare growth of mycobacterium avium subsp. avium on four specific mycobacterial cultures such as glycerinated lowenstein-jensen medium, pyruvate-enriched lowenstein- jensen medium, mycobactin j-supplemented herr...
the aim of this study was to investigate the histopathology of avian tuberculosis in naturally infected domestic pigeons (columba livia var. domestica) with mycobacterium aviumsubsp.avium. avian tuberculosis is one of the most important diseases that affect all species of birds, and is most often caused by mycobacterium avium and mycobacterium genavense. eighty out of more than 600 pigeons were...
Mycobacterium avium subsp. paratuberculosis is genetically similar to other members of the Mycobacterium avium complex (MAC), some of which are nonpathogenic and widespread in the environment. We have utilized an M. avium subsp. paratuberculosis whole-genome microarray representing over 95% of the predicted coding sequences to examine the genetic conservation among 10 M. avium subsp. paratuberc...
background and objectives: pigeons are extensively kept for homing and racing purposes in iran. the main objective of this study was to investigate dissemination of m. avium subsp. avium (maa) in pigeon aviaries in tabriz, north-western iran. materials and methods: postmortem pathologic specimens from thirty-nine out of 140 birds collected from private flocks (n = 3), were subjected to bacteria...
The Mycobacterium avium complex (MAC) consists of four recognized species, Mycobacterium avium, Mycobacterium colombiense, Mycobacterium intracellulare and Mycobacterium chimaera, and a variety of other strains that may be members of undescribed taxa. We report on two isolates of a scotochromogenic, slowly growing, non-tuberculous Mycobacterium species within the M. avium complex from a lymph n...
BACKGROUND Rabbits are susceptible to infection by different species of the genus Mycobacterium. Particularly, development of specific lesions and isolation of Mycobacterium avium subsp. avium and Mycobacterium avium subsp. paratuberculosis, both subspecies of the M. avium complex, has been reported in wildlife conditions. Although, rabbit meat production worldwide is 200 million tons per year,...
background and objectives: avian tuberculosis is one of the most important infections affecting most species of birds. mycobacterium avium can not only infect all species of birds, but also infect some domesticated mammals.the most crucial aspect of control and eradication scheme is identification of infection sources and transmission routs. mo- lecular techniques such as restriction fragment l...

BACKGROUND Cellulitis caused by Mycobacterium avium-intracellulare has rarely been described. Mycobacterium avium-intracellulare is a rare cause of septic arthritis after intra-articular injection, though the causative role of injection is difficult to ascertain in such cases. CASE PRESENTATION A 57-year-old with rheumatoid arthritis treated with prednisone and azathioprine developed bilatera...
Antigens in a 4-week-old culture filtrate (CF) of Mycobacterium avium subsp. avium were separated in sodium dodecyl sulfate-polyacrylamide gel electrophoresis and identified by Western blotting. The culture had minimal lysis of bacilli, giving a CF preparation consisting mainly of secreted proteins. Comparison with a similar CF of Mycobacterium tuberculosis with almost no contamination with int...
