Identification of clinically significant Mycobacterium fortuitum complex isolates.
Recent outbreaks of nosocomial infections caused by organisms identified as the Mycobacterium fortuitum complex suggest that species and subspecies identification is epidemiologically important. In a study of 170 strains, M. fortuitum was differentiated from M. chelonei by nitrate reduction and iron uptake. M. fortuitum was further divided into biovariant fortuitum, biovar peregrinum, and an un...
متن کاملMolecular Identification and Conventional Susceptibility Testing of Iranian Clinical Mycobacterium fortuitum Isolates
Objective(s) Rapidly growing mycobacteria (RGM) are capable of producing diseases in humans. Since mycobacteria vary in their susceptibility, precise identification is critical for adoption of correct drug therapy. The main aim of this study was molecular identification and evaluation of antimicrobial susceptibility pattern of Iranian clinically isolated Myocbacterium fortuitum. Materials and...
متن کاملIdentification of Mycobacterium fortuitum and Mycobacterium chelonei.
The study of 52 strains of rapidly growing mycobacteria showed that Mycobacterium fortuitum and M. chelonei were clearly distinguished by the aid of seven key tests (nitrate reductase, iron uptake, beta-glucosidase, penicillinase, growth on fructose, resistance to pipemidic acid, and resistance to capreomycin) and by analysis of their respective mycolic acids. However, the subdivision of these ...
متن کاملAntimicrobial susceptibility testing of Mycobacterium fortuitum complex.
A total of 24 strains of the Mycobacterium fortuitum complex were tested for susceptibility to antimicrobial agents by the disk diffusion and agar dilution techniques. By comparing zones of inhibition obtained with the disk diffusion technique with results of minimal inhibitory concentration determinations, it was shown that disk diffusion results could predict in vitro susceptibility to select...
متن کاملHeterogeneity of Iranian clinical isolates of Mycobacterium fortuitum
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 ...
