Molecular characterization of Mycobacterium abscessus strains isolated from a hospital outbreak.

High-level Relatedness among Mycobacterium abscessus subsp. massiliense Strains from Widely Separated Outbreaks

Three recently sequenced strains isolated from patients during an outbreak of Mycobacterium abscessus subsp. massiliense infections at a cystic fibrosis center in the United States were compared with 6 strains from an outbreak at a cystic fibrosis center in the United Kingdom and worldwide strains. Strains from the 2 cystic fibrosis outbreaks showed high-level relatedness with each other and ma...

Characterization of mycobacteria from a major Brazilian outbreak suggests that revision of the taxonomic status of members of the Mycobacterium chelonae-M. abscessus group is needed.

An outbreak of postsurgical infections caused by rapidly growing mycobacteria has been ongoing in Brazil since 2004. The degrees of similarity of the rpoB and hsp65 sequences from the clinical isolates and the corresponding sequences from both the Mycobacterium massiliense and the M. bolletii type strains were above the accepted limit for interspecies variability, leading to conflicting identif...

بررسی میزان وفور ژنوتیپ بیجینگ در سویه‌های مایکوباکتریوم توبرکلوزیس جدا شده از بیماران مسلولThe Frequency of Beijing Genotype of Mycobacterium Tuberculosis Isolated from Tuberculosis Patients

    Background & Aim: Molecular epidemiology is the using of molecular techniques (e.g. Spoligotyping, RFLP VNTR) in order to study bacterial distribution in human populations. The aim of this study was to investigate the prevalence of all genotypes in M. tuberculosis strains typed by spoligotyping and to determine the associated risk factors in patients with different nationalities residing in...

Outbreak of infection with Mycobacterium abscessus: is sodium dodecyl sulfate-polyacrylamide gel electrophoresis a useful technique for epidemiological typing?

We have read with interest the article by Zhibang et al. (12) about an outbreak of infections due to Mycobacterium abscessus. We believe, as the authors did, that the strains isolated from the different patients and the environmental samples were the same clone. Classical epidemiology data support this fact, as did conventional microbiology data and plasmid analysis (although only one plasmid w...
