| mycobacterium barrassiae sp. nov., a mycobacterium moriokaense group species associated with chronic pneumonia. | three identical isolates of new rapidly growing mycobacteria (rgm) were recovered from the bronchial aspirate and sputum from a 49-year-old woman presenting with lung lesions. the case met the american thoracic society criteria for the diagnosis of nontuberculous mycobacterial infection. the three isolates grew in 3 days at 24 to 42 degrees c. the 16s rrna gene sequence analysis indicated that the sequences of the isolates were identical and shared 99.7% and 98.1% similarities with those of myco ... | 2006 | 17021072 |
| prevalence of bovine tuberculosis in a dairy cattle farm and a research farm in ghana. | the aim of the study was to estimate the prevalence of bovine tuberculosis (btb) and to identify the mycobacterial species causing btb in a dairy farm and research farm. six hundred and eighty-five cattle were screened for btb by using the comparative intradermal tuberculin test (ctt). positive reactors were slaughtered and carcasses were taken for isolation of mycobacterial species. this was followed by speciation of isolates using both standard conventional and molecular assays. seventeen of t ... | 2014 | 25005431 |
| mycobacterium malmesburyense sp. nov: a novel non-tuberculous mycobacterium species revealed by multiple gene sequence characterization. | non-tuberculous mycobacteria (ntm) are ubiquitous in the environment and an increasing number of ntm species have been isolated and characterized from both humans and animals, highlighting the zoonotic potential of these bacteria. host exposure to ntm may impact on cross-reactive immune responsiveness which may affect diagnosis of bovine tuberculosis and may also play a role in the variability of the efficacy of mycobacterium bovis bcg vaccination against tuberculosis. in this study we character ... | 2016 | 27926825 |
| prevalence and distribution of non-tuberculous mycobacteria (ntm) in cattle, african buffaloes (syncerus caffer) and their environments in south africa. | it has been hypothesized that a variety of non-tuberculous mycobacteria (ntm) species to which livestock and wildlife species are naturally exposed induce broadly cross-reactive anti-mycobacterial immune responses which interfere with current standard diagnostic assays. non-tuberculous mycobacteria have also been implicated in mycobacterium bovis-specific immune responsiveness, hence potentially the development of tuberculosis. cattle and african buffaloes are both maintenance hosts of bovine tu ... | 2013 | 24171852 |
| mycobacterium celeriflavum sp. nov., a rapidly growing scotochromogenic bacterium isolated from clinical specimens. | six strains of a rapidly growing scotochromogenic mycobacterium were isolated from pulmonary specimens of independent patients. biochemical and cultural tests were not suitable for their identification. the mycolic acid pattern analysed by hplc was different from that of any other mycobacterium. genotypic characterization, targeting seven housekeeping genes, revealed the presence of microheterogeneity in all of them. different species were more closely related to the test strains in various regi ... | 2015 | 25389151 |
