We report a case of recurrent disseminated Mycobacterium avium complex (DMAC) disease with anti-gamma interferon autoantibodies. To our knowledge, this is the first reported case caused by reinfection with a separate isolate of M. avium. DMAC disease activity was monitored using serum IgG antibody titers against lipid antigens extracted from a MAC strain.

Organisms within the Mycobacterium avium complex (MAC) may have differential virulence. We compared 33 subjects with MAC pulmonary disease to 75 subjects with a single positive culture without disease. M. avium isolates were significantly more likely to be associated with MAC pulmonary disease (odds ratio = 5.14, 95% confidence interval = 1.25 to 22.73) than M. intracellulare.

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...

PURPOSE The objective of this study is to define the clinical implications of consolidations in nodular bronchiectatic type Mycobacterium avium complex (NBMAC) infection. MATERIALS AND METHODS A total of 69 patients (M : F = 17 : 52; mean age, 64 years; age range, 41-85 years) with MAC isolated in the sputum culture and nodular bronchiectasis on the initial and follow-up CT scans were include...

john`s disease, is an important disease in cattle which the causative agent is mycobacterium avium subsp. paratuberculosis. economic losses, elimination of reactor cattle, high expenses of disease control and causing crohn disease in human made the study of disease more important. knowing the involved area, focal points of disease would be effective to prevent disease. there are several methods...

BACKGROUND Mycobacterioses in animals cause economical losses and certain Mycobacterium avium subspecies are regarded as potential zoonotic agents. The evaluation of the zoonotic risk caused by M. avium subspecies requires information about the quantities of Mycobacterium strains in infected animals. Because M. avium subspecies in pig tissues are difficult or even impossible to quantify by cult...

A combined molecular and cultural method for the detection of the Mycobacterium tuberculosis complex (MTBC) and Mycobacterium avium subsp. paratuberculosis was developed and tested with artificially contaminated milk and dairy products. Results indicate that the method can be used for a reliable detection as a basis for first risk assessments.

Mycobacterium avium subsp. (MAA) is the main tuberculosis pathogen of poultry and wild birds. MAA can also infect mammals such as pigs, cattle, horses pose a threat to people with low immunity. Here, we describe first identification strain HJW isolated from cow in Jilin Province, China. The isolate was completely sequenced phylogenetic analysis its relationship members complex (MAC) performed. ...

Employing 7H11 agar medium at pH 6.6, the MICs of clarithromycin for 50% (MIC50) and 90% (MIC90) of 19 strains of Mycobacterium avium complex were 8 and 16 micrograms/ml, respectively. However, the MICs were 2 to 3 log2 dilutions lower in the 7H11 medium adjusted to pH 7.4, and the MICs on 10% OADC (oleic acid-albumin-dextrose-catalase)-enriched Mueller-Hinton agar at pH 7.3 were also 2 log2 di...

We present two cases of pulmonary MAC infection in women with Hürthle cell thyroid carcinoma. Both cases were asymptomatic octogenarian women with active Hürthle cell thyroid carcinoma and prolonged periods of hypothyroidism prior to diagnosis of pulmonary MAC. Mycobacterium avium complex has never been reported in association with any type of thyroid cancer, specifically Hürthle cell carcinoma...
