Mycobacterium avium causes tuberculosis in chickens and other fowls but can also infect an extensive range of different animal species. The authors reviewed the available literature on this organism to show the importance of M avium infection.

Crohn's disease may be triggered by an infection, and it is plausible to consider that such an infection may be animal borne and ingested with our food. There has been considerable interest in the past in determining whether Mycobacterium avium subsp. paratuberculosis (M. avium) might be the etiologic agent in Crohn's disease since it causes a disease in cattle that is similar to Crohn's diseas...

Free-living protists are ubiquitous in the environment and form a potential reservoir for the persistence of animal and human pathogens. Mycobacterium avium subsp. paratuberculosis is the cause of Johne's disease, a systemic infection accompanied by chronic inflammation of the intestine that affects many animals, including primates. Most humans with Crohn's disease are infected with this chroni...

The bactericidal activities of four injectable antituberculosis drugs, streptomycin, amikacin, kanamycin, and capreomycin, against Mycobacterium avium and M. tuberculosis were tested. All four drugs were highly bactericidal against M. tuberculosis, with low MBC/MIC ratios and MBCs significantly lower than the maximum achievalbe concentrations in serum (Cmax). In contrast, all four drugs had ver...

Risk of Mycobacterium avium complex disease was examined in human immunodeficiency virus (HIV)-infected patients with and without a history of tuberculosis. Information was obtained by retrospective review of charts of patients in HIV clinics in 10 US cities. Among 1363 patients with <200 CD4 cells/mm3 seen at Grady Memorial Hospital (GMH), 11 (17%) of 66 with a history of a positive purified p...

Three reference and 16 field strains of Mycobacterium paratuberculosis were tested with the Gen-Probe Mycobacterium avium complex DNA probe (Gen-Probe Inc., San Diego, Calif.). All reference strains and 12 of 16 field strains gave positive hybridization results with the probe. This study shows that the M. avium complex probe does not distinguish between M. avium and M. paratuberculosis and indi...

Sera from patients with disease caused by the Mycobacterium avium complex (M. avium and M. intracellulare), M. kansasii, or M. tuberculosis and from subjects who did not have a mycobacterial disease were tested by enzyme-linked immunosorbent assay against peptidoglycolipid antigens representing each of the 15 most common serovars of the M. avium complex and against crude protein antigen extract...

Creation of a reliable and easy to use serologic test would greatly improve ante mortem diagnosis of Mycobacterium avium subsp. avium and aid in the control of avian mycobacteriosis, particularly in captive birds. In order to determine whether serodiagnostics could be of value in testing ring-neck doves (Streptopelia risoria) for M. a. avium infection, Western blot analysis was used to assess t...
