A new crystalline reagent for nitrate reductase tests was compared with standard liquid reagents on 437 strains of mycobacteria. The results for isolates of Mycobacterium avium complex, Mycobacterium kansasii, Mycobacterium gordonae, Mycobacterium scrofulaceum, Mycobacterium fortuitum, and Mycobacterium chelonei agreed 100% with the expected results. Of the 177 Mycobacterium tuberculosis isolat...

Mycobacterium sp. strain shizuoka-1 is a rapidly growing scotochromogenic mycobacterium and was isolated from well water for a bathing facility in Shizuoka Prefecture in Japan. Here, we report the draft sequence of its genome, comprising a 6.5-Mb chromosome. This mycobacterium has 83.1% identity with Mycobacterium rhodesiae, a human pathogen.

Objective: To evaluate the antibacterial effect in vitro of moxifloxacin and linezolid on nontuberculous mycobacterium (NTM), and provide scientific evidence for treatment of NTM disease. Materials and methods: From January 2012 to June 2014, a total of 98 NTM strains were collected from suspected tuberculosis patients (n=98) in our hospital. The minimal inhibitory concentration (MIC) of the mo...

The taxonomic position of a polycyclic-aromatic-hydrocarbon-degrading bacterium, strain 17A3(T), isolated from contaminated soil was determined using a combination of phenotypic and genotypic properties. The isolate showed phenotypic properties that were diagnostic for species of the genus Mycobacterium. Comparative 16S rRNA gene sequence analysis assigned 17A3(T) to the 16S rRNA gene subgroup ...

Mycobacterium wolinskyi is a rapidly growing mycobacterium, first described in 1999 as a member of the group Mycobacterium smegmatis (Mycobacterium smegmatis, Mycobacterium wolinskyi and Mycobacterium goodii). Only 19 case reports all over the world have been described on literature, none of them in Brazil. On this report, it is described one case of infection after a mammoplasty procedure perf...

online | memorias.ioc.fiocruz.br Bovine tuberculosis (BTB) is an infectious disease primarily caused by Mycobacterium bovis, which affects a wide range of mammals, including humans (Amanfu 2006). M. bovis is a member of the Mycobacterium tuberculosis complex (MTBC), which also includes M. tuberculosis, Mycobacterium africanum, Mycobacterium canetti, Mycobacterium microti, Mycobacterium caprae a...

Investigating the Effects of Changing Pattern AIDS Transmission on Prevalence Mycobacterium Tuberculosis in Patients with HIV by Microscopic and Molecular Methods

Synthetic iridium-, rhodium-, and ruthenium-amino acid complexes with hydrophobic l-amino acids have antibiotic activity against Mycobacterium spp., including Mycobacterium bovis BCG and the rapidly growing species Mycobacterium abscessus and Mycobacterium chelonae. Concentrations of transition metal-amino acid complexes demonstrating hemolysis or cytotoxicity were 10- to 25-fold higher than we...

A new DNA probe assay (INNO LiPA Mycobacteria; Innogenetics, Ghent, Belgium) for the simultaneous identification, by means of reverse hybridization and line-probe technology, of Mycobacterium tuberculosis complex, Mycobacterium kansasii, Mycobacterium xenopi, Mycobacterium gordonae, the species of the Mycobacterium avium complex (MAC), Mycobacterium scrofulaceum, and Mycobacterium chelonae was ...

Cystic fibrosis patients are highly susceptible to infections with non-tuberculous mycobacteria. Especially Mycobacterium abscessus infections are common but reliable diagnosis is hampered by non-specific clinical symptoms and insensitive mycobacterial culture. In the present study we established novel methods for rapid detection and immune characterization of Mycobacterium abscessus infection ...
