Prompt detection of drug resistance in Mycobacterium tuberculosis is essential for effective control of tuberculosis (TB). We developed a Multi-PCR-SSCP method that detects more than 80% commonly observed isoniazid (INH) and rifampin (RIF) resistance M. tuberculosis in a single assay. The usefulness of the newly developed method was evaluated with 116 clinical isolates of M. tuberculosis. Disti...

Early diagnostics of resistance to fluoroquinolones facilitates early start adequate therapy and increases the chance a favorable outcome tuberculosis. Application genetic methods permits obtain within 1–2 days results Mycobacterium tuberculosis detection anti-tuberculosis drugs, unlike classical requiring up 1−2 month. The aim study is develop method for M. identification point mutations in co...

Mycobacterium bovis strains isolated from tuberculosis (TB) lesions from 1138 cattle slaughtered at Kombolcha abattoir in north eastern Ethiopia were characterised. Detailed postmortem examination, bacteriological culturing, regions of difference PCR and spoligotyping were used. At least one TB lesion was observed in 57 (5 per cent) of the cattle, of which 27 (47 per cent) yielded mycobacteria ...

This study described a case of transmission of Mycobacterium tuberculosis infection from a man to cattle confirmed by using Bioline® and multiplex PCR known as Genotype® MTBC Kit. A dairy farm was screened using caudal fold intradermal tuberculin test, and a heifer reacted positively to the bovine tuberculin but showed no gross pathological lesions at slaughter. The cattle attendant was also di...

The role of previous treatment in the dynamics of tuberculosis transmission has not been adequately investigated. Mycobacterium tuberculosis isolates from previously treated patients (n = 88) from all regions of Syrian Arab Republic were characterized in terms of antibiotic sensitivity and genotyping using double-repetitive-element polymerase chain reaction (DRE-PCR) method for the proximity of...

background: tuberculous endometritis is often a diagnostic dilemma for gynecologists in the evaluation of infertility. this study evaluated and compared different diagnostic methods in tuberculous endometritis. methods: 100 infertile women were investigated for tuberculous endometritis. the endometrial samples obtained by curettage were evaluated by ziehl-neelsen (zn) staining of the smears for...

Mycobacterium avium subsp. avium (Maa) is an intracellular pathogen belonging to the Mycobacterium avium-intracellulare complex (MAC). Reservoirs of MAC are the natural environment, wildlife and domestic animals. In adult bovine, MAC infections are typically caused by Mycobacterium avium subsp. paratuberculosis (Map). Maa infections in bovine are rarely reported but may cause clinical disease a...

A rapid, inexpensive, simple, and accurate multiplex polymerase chain reaction (PCR) was developed in a single tube for identification of Mycobacterium tuberculosis. Assessment of sensitivity and specificity of simple PCR was performed with 116 strains of M. tuberculosis complex (MTC) and 144 strains of nontuberculous mycobacteria (NTM) compared with the biochemical method. Specific amplificati...

The presence of enterobacterial repetitive intergenic consensus (ERIC) sequences was demonstrated for the first time in the genome of Mycobacterium tuberculosis; these sequences have been found in transcribed regions of the chromosomes of gram-negative bacteria. In this study genetic diversity among clinical isolates of M. tuberculosis was determined by PCR with ERIC primers (ERIC-PCR). The stu...

The current "gold standard" in molecular epidemiological studies of Mycobacterium tuberculosis is IS6110 RFLP based on IS6110 polymorphism. However PCR-based methods are becoming increasingly important. Recently, fast ligation-mediated PCR (FLiP), based on IS6110 polymorphism was proposed. In this study, the discriminatory power of FLIP, spoligotyping and MIRU-VNTR typing, in differentiation of...
