The capacities of differentiation of Mycobacterium bovis BCG from other members of M. tuberculosis complex species using PCR-RFLP, multiplex PCR, and PCR-based genomic deletion analysis approaches were compared. In the study, mycobacteria isolated from patients suspected of adverse events following vaccination with BCG, primarily classified according presence of RD1 marker as virulent and avirulent...
Tuberculosis (TB) continues to be one of the most challenging public health problems in the world. An important contributor to the global burden of the disease is the emergence and spread of drug-resistant and particularly multidrug-resistant Mycobacterium tuberculosis strains (MDR), defined as being resistant to at least isoniazid and rifampicin. In recent years, the introduction of different DNA-based...
Sixty-one isolates of M. bovis (58 from cattle and three from wild animals) from eight regions of Poland were analysed. Molecular analysis was done using HAIN and spoligotyping methods. Drug susceptibility of the isolates to streptomycin, izoniazid, rifampicin, ethambutol, and pyrazinamide was tested by proportional methods on solid and liquid media. By spoligotyping, 47 (77%) isolates were identified...
In total, 48 Mycobacterium tuberculosis clinical isolates from 48 patients with drug-resistant pulmonary tuberculosis (TB) in central Poland during 2004 were analysed by spoligotyping and IS6110-Mtb1/Mtb2 PCR. Twelve (25%) isolates were clustered by spoligotyping in combination with IS6110-Mtb1/Mtb2 PCR. Patients from whom these isolates were obtained were assumed to have developed TB as a result...
