IS986 of Mycobacterium tuberculosis belongs to the IS3-like family of insertion sequences, and it has previously been shown to be present in multiple copies in the chromosome of M. tuberculosis. In this study we investigated the value of a IS986-based DNA probe in the diagnosis and epidemiology of tuberculosis. IS986 was found only in species belonging to the M. tuberculosis complex. Independen...

Mycobacterium africanum is a member of the Mycobacterium tuberculosis complex (MTBC) and an important cause of human tuberculosis in West Africa that is rarely observed elsewhere. Here we genotyped 613 MTBC clinical isolates from Ghana, and searched for associations between the different phylogenetic lineages of MTBC and patient variables. We found that 17.1% (105/613) of the MTBC isolates belo...

the increasing incidence of multi drug resistance tuberculosis (mdr-tb) and extensively drug resistance tb (xdr-tb) worldwide highlight the urgent need to search for newer anti-tuberculosis compounds. it has been determined that pharmaceutical plant, hops ( humulus lupulus ), possesses some antibacterial effect. in this study, the antimycobacterial effect of this plant on rifampin sensitive and...

Abstract The treatment of leprosy is long and complex, benefiting from the development sterilizing, rapidly-acting drugs. Reductive evolution made Mycobacterium leprae exquisitely sensitive to Telacebec, a phase 2 drug candidate for tuberculosis. unprecedented potency Telacebec against M. warrants further validation in clinical trials.

We investigated the use of DNA amplification by polymerase chain reaction (peR) for detection of Mycobacterium tuberculosis in 300 patients who were suspected of having pulmonary tuberculosis and compared the results with culture results which were performed in parallel with PCR. Two-thirds of each sample was processed for smear and culture by standard methods and one-third was prepared fo...

AbstractChronic sialadenitis is a disease of salivary glands associated with chronic infections,systemic diseases and silolithiasis pathogenesis of the disease. Primary tuberculoussubmandibulitis is not a reported disease. The diagnosis was confirmed whena 45 years old lady suspicious to submandibular gland tumor was operated on for excisionalbiopsy. Histological examination of the specimen by ...

Mycobacterium orygis, previously called the oryx bacillus, is a member of the Mycobacterium tuberculosis complex and has been reported only recently as a cause of human tuberculosis in patients of South Asian origin. We present the first case documenting the transmission of this organism from a human to a cow.

It is not known whether atypical Mycobacterium (AM) causes peritonitis in humans. We described a case of tuberculosis-like peritonitis caused by an AM. Genetic analysis of the biopsy specimens suggested an AM infection. Thus, we concluded that peritonitis in humans can be caused by some AM species as well as by Mycobacterium tuberculosis complex.

We compared the in vitro antimycobacterial activity of a new fluoroquinolone, HSR-903, with strong activity against gram-positive cocci with those of levofloxacin (LVFX), sitafloxacin (STFX), and gatifloxacin (GFLX). The MICs of the quinolones for Mycobacterium tuberculosis and Mycobacterium avium complex were in the order STFX approximately GFLX < LVFX <== HSR-903 and STFX <== GFLX <== HSR-903...

A multiplex PCR designed to differentiate Mycobacterium tuberculosis complex organisms from M. avium and M. intracellulare was used to test 105 isolates identified by DNA probe methods as M. avium, M. intracellulare, or M. avium complex type X. The multiple PCR correctly identified 33 of 34 isolates identified by commercial probe methods as M. avium and all 51 isolates identified as M. intracel...
