Rapid-growth mycobacteria were isolated from two cases of cow mastitis with similar clinical appearance and within a narrow time frame. Mycobacteria on blood esculine agar. The Gram stained, Ziehl-Nielsen stained tested for growth at 25°C, 37°C 42°C, iron uptake, Löwenstein-Jensen (LJ) agar without 5% NaCl, arylsulphatase (3 days), tween 80 hydrolysis, tellurite reduction, nitrate reductase nia...

The Mycobacterium avium complex (MAC) consists of four recognized species, Mycobacterium avium, Mycobacterium colombiense, Mycobacterium intracellulare and Mycobacterium chimaera, and a variety of other strains that may be members of undescribed taxa. We report on two isolates of a scotochromogenic, slowly growing, non-tuberculous Mycobacterium species within the M. avium complex from a lymph n...

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...

Mycobacterium massiliense, an emerging pathogen that is increasingly reported as a causative agent in infections occurring during medical procedures, is difficult to be identified using conventional methods. Here we report the case of a cutaneous M. massiliense infection that was associated with repeated surgical procedures and that was identified via a comparative sequence analysis of rpoB and...

We herein present the third set of documented clinical Mycobacterium setense cases. Three clinically unrelated isolates were identified and characterized using various key conventional and molecular diagnostic tests. Phenotypic and molecular data analysis, particularly 16S rDNA, hsp65, and rpoB sequencing, provided evidence of M. setense involvement in clinical infections in Iranian patients. O...

We determined nucleotide sequences of rpoB, hsp65, and sodA in 59 clinical isolates (from 58 patients) of the Mycobacterium abscessus group. Identification to the species level, based on three target genes, was concordant for 44 isolates (25 M. abscessus, 13 Mycobacterium massiliense, and 6 Mycobacterium bolletii isolates) and discordant for 15 isolates which had "interspecific composite patter...

Atherosclerosis bears many similarities to inflammatory/autoimmune diseases like rheumatoid arthritis and multiple sclerosis (MS).1,2 Compelling data from experimental models show that such diseases may be treated by vaccination. Will it be possible to attack atherosclerotic cardiovascular disease with the same approach? Several studies have shown positive effects of immunization with antigenic...
