background and objectives: the increase of infections caused by nontuberculous mycobacteria (ntm) is receiving increasing attention worldwide. mycobacterium fortuitum is encountered with increasing frequency in clinical laboratories of iran. materials and methods: sequence variation of 48 m. fortuitum clinical isolates, were investigated by sequence analysis of the 16s-23s internal transcribed ...

Incidence and prevalence of Mycobacterium fortuitum infection vary greatly by location and death is very rare except in disseminated disease in immunocompromised individuals. We present what we believe is the first case of bone marrow infection with Mycobacterium fortuitum in an HIV negative patient. Bone marrow examination revealed presence of numerous acid fast bacilli which were confirmed as...

When tested against 312 clinical isolates of rapidly growing mycobacteria, the quinolone pipemidic acid correctly separated Mycobacterium chelonae (M. chelonei) from Mycobacterium fortuitum biovar fortuitum but not from biovar peregrinum or the third biovar complex. The new 4-quinolone ciprofloxacin correctly separated all three biovars of M. fortuitum from M. chelonae and appears to provide a ...

Mycobacterium fortuitum is a non-tuberculous fast-growing mycobacterium which is frequently acquired from environmental sources such as soil and water. Since it is an opportunist pathogen, it is associated with trauma, surgery or immunodeficiency. The current report describes a case of Mycobacterium fortuitum-caused disseminated lesions on the skin of an immunocompetent patient.

INTRODUCTION Mycobacterium fortuitum is a rapidly growing group of nontuberculous mycobacteria more common in patients with genetic or acquired causes of immune deficiency. There have been few published reports of Mycobacterium fortuitum associated with breast infections mainly associated with breast implant and reconstructive surgery. CASE PRESENTATION We report a case of a 51-year-old Cauca...

The antimicrobial activities of telithromycin (HMR 3647) and seven other antimicrobials against 94 strains of rapidly growing mycobacteria were determined. Telithromycin at a concentration of 1 microg/ml inhibited Mycobacterium peregrinum (100%), Mycobacterium chelonae (80%), Mycobacterium abscessus-Mycobacterium mucogenicum (44.4%), and Mycobacterium fortuitum (2.1%). All or most strains of M....

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...

We studied the taxonomic positions of the rapidly growing organism Mycobacterium fortuitum and phenotypically related organisms. We confirmed that “Mycobacterium peregrinum” ATCC 14467T (T = type strain) is genetically independent of M. fortuitum ATCC 6841T by using various DNA hybridization conditions. Strains that were genetically identified as “M. peregrinum” were phenotypically differentiat...

The occurrence of Mycobacterium species in clinically healthy pet reptiles was studied in Italy during the period 2004-2006. The feces samples of 223 animals were examined bacteriologically. Thirty-seven strains were isolated, in particular from 13/18 (72.2%) ophidians, 13/134 (9.7%) saurians and 11/71 (15.5%) chelonians. The isolates were classified, after HPLC analysis of bromophenacyl esters...

Mycobacterium fortuitum is a rapidly growing nontuberculous Mycobacterium that can cause a range of diseases in humans. Complications from M. fortuitum infection have been associated with numerous surgical procedures. A protective immune response against pathogenic mycobacterial infections is dependent on the granuloma formation. Within the granuloma, the macrophage effector response can inhibi...
