PURPOSE OF REVIEW Although the incidence of tuberculosis has reduced in developed countries, there is a growing interest in nontuberculous mycobacteria (NTM) as a cause of lung disease. However, NTM are a heterogeneous group and most of the data come from only three species: Mycobacterium avium complex, Mycobacterium kansasii and Mycobacterium abscessus. Still, information about these three spe...

OBJECTIVE A group of patients with pulmonary tuberculosis (PT) who received and correctly completed antituberculous therapy were studied to determine the incidence and significance of positive acid-fast bacilli (AFB) in sputum smears at the end of this treatment. DESIGN Retrospective chart review of persons with bacteriologically proved PT. PATIENTS Of 1,052 patients diagnosed as having PT ...

BACKGROUND The incidence of nontuberculous mycobacteria (NTM) infections is increasing worldwide, however formal evaluations of the epidemiology of NTM infections are limited. Understanding the trends and true prevalence of NTM is a major priority for optimizing infection control programmes and resources. The purpose of this study was to investigate the epidemiology, clinical manifestations, an...

Mycobacterium vaccae is a rapidly growing, nontuberculous Mycobacterium species that is generally not considered a human pathogen and is of major pharmaceutical interest as an immunotherapeutic agent. We report here the annotated genome sequence of the M. vaccae type strain, ATCC 25954.

During the period 1979-1982, 70 strains of atypical mycobacteria isolated from clinical material were identified as belonging to species or species complex. Twenty-eight out of 61 strains isolated from pulmonary specimens were identified as M. avium-intracellulare. This frequency of association of M. avium-intracellulare with sputa of patients with pulmonary symptoms points to its potential imp...

We report a rare mesenteric localized Mycobacterium genavense infection in a severely immunocompromised human immunodeficiency virus-infected patient. An INNO-LiPA MYCOBACTERIA v2 test was performed directly on biopsy samples. This new molecular tool could be used for simultaneous identification of mycobacterium species from human specimens, but other studies are needed to validate our first re...
