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...

The incidence of Mycobacterium avium-Mycobacterium intracellulare complex infections has increased in recent years primarily because a significant proportion of acquired immunodeficiency syndrome patients develop disseminated M. avium complex disease. In an effort to develop new tools to study these infections, we have produced eight monoclonal antibodies directed against M. avium. Western blot...

A multiplex PCR designed to differentiate Mycobacterium tuberculosis complex organisms from M. avium and M. intracellulare was used to test 105 isolates identified by DNA probe methods as M. avium, M. intracellulare, or M. avium complex type X. The multiple PCR correctly identified 33 of 34 isolates identified by commercial probe methods as M. avium and all 51 isolates identified as M. intracel...

Mycobacterium avium subsp. avium (Maa) is an intracellular pathogen belonging to the Mycobacterium avium-intracellulare complex (MAC). Reservoirs of MAC are the natural environment, wildlife and domestic animals. In adult bovine, MAC infections are typically caused by Mycobacterium avium subsp. paratuberculosis (Map). Maa infections in bovine are rarely reported but may cause clinical disease a...

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 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...

Objective: To evaluate the antibacterial effect in vitro of moxifloxacin and linezolid on nontuberculous mycobacterium (NTM), and provide scientific evidence for treatment of NTM disease. Materials and methods: From January 2012 to June 2014, a total of 98 NTM strains were collected from suspected tuberculosis patients (n=98) in our hospital. The minimal inhibitory concentration (MIC) of the mo...
