OBJECTIVE To determine the sensitivity of differential avian and human delayed-type hypersensitivity skin testing in the diagnosis of non-tuberculous mycobacterial lymphadenitis. METHOD Retrospective review of all patients with culture proved non-tuberculous mycobacterial lymph node infections who also had differential avian and human skin testing performed over a 10 year period from 1986 to ...

The phoA gene fusion methodology permitted the identification of a new Mycobacterium tuberculosis exported protein, Des. This protein has significant sequence similarities to plant acyl-acyl carrier protein desaturases, which are enzymes involved in general fatty acid biosynthesis as well as in mycolic acid biosynthesis in mycobacteria. As shown by Western blot and enzyme-linked immunosorbent a...

The proportion of non-tuberculous mycobacteria to Mycobacterium tuberculosis cultivated in the laboratory has been recently increasing. Numerous skin and soft tissue infections have been reported, while osteomyelitis is reported very rarely. A delayed diagnosis can cause a wide range of bone destruction and joint contracture, which highlights the importance of early recognition of osteomyelitis...

Mycobacterium wolinskyi belongs to the Mycobacterium smegmatis group, which comprises rapidly growing non-tuberculous mycobacteria. The number of case reports on M. wolinskyi infections associated with postoperative wounds has increased in recent years. We herein report a case of peritonitis due to M. wolinskyi after peritoneal catheter embedment surgery. Identification was achieved based on 16...

It is known that the cultural characteristics of strains of Mycobacterium tuberculosis isolated from tuberculous secretions may be changed under the influence of anti-tuberculosis drugs. It has been suggested that this is due to " biological disintegration" of the bacteria (Lanyi and Eidus, 1954). The process is usually a gradual one. The present report is concerned with the isolation from lary...

Isolation and differentiation of various species of mycobacteria are predominantly based on conventional, cultural and biochemical tests. Among the non-tuberculous mycobacteria, these tests are unable to differentiate M. scrofulaceum from M. avium-intracellulare (MAI) because of their identical biochemical characteristics. For this reason, one hundred mycobacterial strains suspected to be M. ...

Atypical mycobacteria are pathogens that uncommonly infect the hand. These organisms capable of causing extensive bone damage in Mycobacterium kansasii is a slow growing non-tuberculous Mycobacterium. It second most common mainly affects hand and joints. Immunosuppressed patients more likely to develop infection. Because extrapulmonary involvement M. rare, skin soft tissue infections infrequent...
