| mycobacterium septicum sp. nov., a new rapidly growing species associated with catheter-related bacteraemia. | rapidly growing mycobacteria are capable of causing several clinical diseases in both immunosuppressed and immunocompetent individuals. a previously unidentified, rapidly growing mycobacterium was determined to be the causative agent of central line sepsis in a child with underlying metastatic hepatoblastoma. four isolates of this mycobacterium, three from blood and one from the central venous catheter tip, were studied. phenotypic characterization, hplc and genetic analysis revealed that while ... | 2000 | 10758863 |
| taxonomic variation in the mycobacterium fortuitum third biovariant complex: description of mycobacterium boenickei sp. nov., mycobacterium houstonense sp. nov., mycobacterium neworleansense sp. nov. and mycobacterium brisbanense sp. nov. and recognition of mycobacterium porcinum from human clinical isolates. | the mycobacterium fortuitum third biovariant complex (sorbitol-negative and sorbitol-positive) contains unnamed taxa first characterized in 1991. these organisms can cause respiratory infections, a spectrum of soft tissue and skeletal infections, bacteraemia and disseminated disease. to evaluate this group of organisms, clinical reference isolates and the type strains of m. fortuitum third biovariant complex sorbitol-negative (n = 21), m. fortuitum third biovariant complex sorbitol-positive (n = ... | 2004 | 15388725 |
| isolation of mycobacterium septicum from the sputum of a patient suffering from hemoptoic pneumonia. | a rapidly growing mycobacterium was isolated in pure culture from the sputum of a 78-year-old woman suffering from hemoptoic pneumonia. the isolate exhibited an antimicrobial susceptibility pattern and a biochemical profile similar to that of mycobacterium septicum atcc 700731(t) and shared 100% 16s rrna gene sequence similarity with this type strain over 1480 bp. its partial rpob sequence shared 98.2% similarity with the latter species, suggesting the isolate was representative of a sequevar of ... | 2006 | 16364605 |
| catheter-related bloodstream infections caused by rapidly growing nontuberculous mycobacteria: a case series including rare species. | rapidly growing nontuberculous mycobacteria (rgms) are responsible for a variety of clinical syndromes in humans including catheter-related blood stream infections (crbsis). recently, we identified a cluster of rgm-associated crbsi at our institution. we describe the epidemiologic and clinical patterns associated with these infections. we conducted a retrospective single-center review of rgm crbsi between may 2004 and june 2005. rgms isolated from blood cultures of 6 patients included mycobacter ... | 2008 | 18294801 |

| non-tuberculous mycobacteria in south african wildlife: neglected pathogens and potential impediments for bovine tuberculosis diagnosis. | non-tuberculous mycobacteria (ntm) are not only emerging and opportunistic pathogens of both humans and animals, but from a veterinary point of view some species induce cross-reactive immune responses that hamper the diagnosis of bovine tuberculosis (btb) in both livestock and wildlife. little information is available about ntm species circulating in wildlife species of south africa. in this study, we determined the diversity of ntm isolated from wildlife species from south africa as well as bot ... | 2017 | 28194371 |
| diversity, community composition, and dynamics of nonpigmented and late-pigmenting rapidly growing mycobacteria in an urban tap water production and distribution system. | nonpigmented and late-pigmenting rapidly growing mycobacteria (rgm) have been reported to commonly colonize water production and distribution systems. however, there is little information about the nature and distribution of rgm species within the different parts of such complex networks or about their clustering into specific rgm species communities. we conducted a large-scale survey between 2007 and 2009 in the parisian urban tap water production and distribution system. we analyzed 1,418 wate ... | 2013 | 23835173 |
| mycobacterium lutetiense sp. nov., mycobacterium montmartrense sp. nov. and mycobacterium arcueilense sp. nov., members of a novel group of non-pigmented rapidly growing mycobacteria recovered from a water distribution system. | from our recent survey of non-pigmented rapidly growing mycobacteria in the parisian water system, three groups of isolates (taxons 1-3) corresponding to possible novel species were selected for taxonomic study. the three taxa each formed creamy white, rough colonies, had an optimal growth temperature of 30 °c, hydrolyzed tween 80, were catalase-positive at 22 °c and expressed arylsulfatase activity. all three were susceptible to amikacin, ciprofloxacin and tigecycline. the three taxa produced s ... | 2016 | 27375118 |
| noncontiguous genome sequence of mycobacterium septicum strain dsm 44393t. | the rapidly growing mycobacterium septicum rarely causes pulmonary infections. we report here the draft genome sequence of m. septicum strain dsm 44393(t), isolated from catheter-related bacteremia and initially identified as a member of mycobacterium fortuitum. | 2013 | 23950116 |
| the first case of pulmonary disease caused by mycobacterium septicum in china. | mycobacterium septicum is a rapidly growing mycobacterium (rgm) that rarely causes pulmonary disease globally. we describe a case of m. septicum pulmonary disease, which to our knowledge is the first reported in china. the isolates were identified as m. septicum and were susceptible in vitro to amikacin, ciprofloxacin, ofloxacin, levofloxacin, kanamycin, and sulfamethoxazole. | 2013 | 23352491 |
