The prevalence of lung diseases caused by nontuberculous mycobacteria (NTM) is increasing worldwide. Unlike pulmonary tuberculosis, endobronchial NTM diseases are very rare with the majority of cases reported in patients with human immunodeficiency virus infection and acquired immune deficiency syndrome. We reported a rare case of endobronchial Mycobacterium avium disease associated with lobar ...

Nontuberculous mycobacteria, which are widespread in the environment, frequently cause opportunistic infections in immunocompromised patients. We report the first case of a patient with chronic granulomatous dermatitis caused by a rarely described organism, Mycobacterium intermedium. The infection was associated with exposure in a home hot tub.

IFN-gamma is critical in the immune response to mycobacterial infections, and deficits in IFN-gamma production and response have been associated with disseminated nontuberculous mycobacterial infections. Mutations in the IFN-gamma receptor ligand-binding chain (IFNgammaR1) have been shown to confer susceptibility to severe infection with nontuberculous mycobacteria. However, mutations in the IF...

Nontuberculous mycobacteria were identified from 45891 samples of 19553 patients with a prediagnosis of pulmonary tuberculosis between November 2004 and January 2009. Among 10041 (21.9%) culture positive samples, 208 (2.1%) pulmonary samples recovered from 77 individual patients were differentiated as mycobacteria other than tuberculosis (MOTT). Proportion of mycobacteria evaluated as causative...

Mycobacterium triplex, a recently described slowly growing nontuberculous mycobacterium, was isolated from a Finnish patient with pulmonary mycobacteriosis. The disease was successfully treated with antimycobacterial drugs. The strain isolated, which was similar to the type strain but differed slightly from the species description, was regarded as a variant of M. triplex sensu stricto. Accordin...

We present a case report of an atypical fibroxanthoma on the cheek of a 73-year-old man. Clinical, dermatoscopic and dermatopathologic images are presented.

introduction: Cosmetic surgery tourism has become increasingly popular despite many associated risks. Outbreaks of atypical mycobacterium surgical site infections in various countries have been particularly notable. While these difficult-to-treat infections are concerning to patients and providers, their economic impact is not well-defined in the literature. We sought to investigate the patient...

We report on a case of disseminated infection with central nervous system involvement due to an atypical mycobacterium related to Mycobacterium triplex in a severely immunodepressed human immunodeficiency virus-infected man.

The aim of the present study was to determine the clinical relevance of Mycobacterium simiae isolation from clinical samples. The medical files of patients in the Netherlands from whom M. simiae was isolated between 1999 and 2006 were reviewed in order to assess frequency and clinical relevance. Clinical relevance was defined as fulfilment of the diagnostic criteria of the American Thoracic Soc...

MYCOBACTERIUM FORTUITUM is considered a ubiquitous, rapidly growing atypical mycobacterium readily isolated from soil, water, domestic and wild animals, milk, and foods. 1 Although originally believed to be a saprophyte, M. fortuitum has become rarely associated with human infections. Most commonly, reported clinical infections are postsurgical, cutaneous, or pulmonary. 2 The rise in clinical s...
