Mycobacterium species has a specific morphology when grown in liquid medium. Mycobacterium tuberculosis complex (MTB) often exhibits serpentine cording, which is different from the dot and cross-barring morphology observed in Mycobacterium avium complex (MAC) and Mycobacterium kansasii (MK), respectively. These characteristic morphologies can be used as a cost-effective method for rapid, presum...

Genetic assessment by spoligotyping of 565 Mycobacterium tuberculosis complex strains collected from the Western Region of Cameroon between 2004 and 2005 has confirmed the establishment of the "Cameroon family" as the leading cause of tuberculosis in 45.9% of cases and evidenced the rapid quasi extinction of Mycobacterium africanum, isolated in 3.3% of tuberculosis cases.

A new mycobacteriophage-based technique (PhageTek MB) was compared with standard culture and staining techniques for diagnosis of pulmonary tuberculosis. A total of 2,048 respiratory specimens from 1,466 patients collected from February 2000 to March 2001 were studied by both (i) conventional methods (direct microscopic examination [auramine-rhodamine fluorochrome], and culture in BacT/ALERT 3D...

PURPOSE The Mycobacterium tuberculosis complex comprises M. tuberculosis, M. bovis, M. bovis bacillus Calmette-Guérin (BCG) and M. africanum, and causes tuberculosis in humans and animals. Identification of Mycobacterium spp. and M. tuberculosis complex to the species level is important for practical use in microbiological laboratories, in addition to optimal treatment and public health. MATE...

In summary, in order to control tuberculosis, we require a rapid diagnosis of TB patients, who act as the source of disease; and if remain untreated, these patients can spread the disease throughout the population. Therefore, we need to introduce the new approach for quick and accurate identification of Mycobacterium tuberculosis, and CYP141 gene is a new approach for rapid and accura...

conclusions: pcr method is a valuable, cost-effective and alternative tool for quick diagnosis of active tuberculosis in different clinical specimens. results: the concordance rate between the three sets of primers was calculated and is6110/buffer pcr method showed good agreement with the lj culture method (κ = 0.627, p < 0.0001). the sensitivity of is6110/buffer pcr was 58.33%, with specificit...

Mycobacteria strains belonging to the Mycobacterium tuberculosis complex were isolated from seals found in the South Atlantic. The animals were received in Mundo Marino installations and treated for Mycobacterium tuberculosis complex by conventional therapy of intensive care and enriched food supply; however, in all cases treatment failed. Necropsies of all animals revealed extensive lesions co...

in most countries, tuberculosis caused by mycobacterium bovis is mainly a disease of cattle but can infect buffalos too. the disease can be controlled successfully by mean of a test-and-slaughter program. in iran test-and-slaughter program has started since 1971 and prevalence of bovine tuberculosis reduces from 5% to less than 0.12% in recent years. in western azarbaijan, north west of iran, t...

Whole chromosomal DNA probes were used to identify clinical isolates of Mycobacterium tuberculosis, Mycobacterium avium complex, and Mycobacterium gordonae. The probe for M. tuberculosis was prepared from Mycobacterium bovis BCG, which has been shown to be closely related to M. tuberculosis. A probe for the M. avium complex was prepared from three strains representing each of the three DNA homo...

Tuberculosis in seals is caused by Mycobacterium pinnipedii, a member of the Mycobacterium tuberculosis complex. In this study, we evaluated the extent of genetic variability among Mycobacterium bovis and M. pinnipedii by microarray-based comparative genomics. We identified two deletions that are exclusive to M. pinnipedii: PiD1 that removes the orthologues of the M. tuberculosis genes Rv3530c ...
