Differentiation of Mycobacterium tuberculosis complex by PCR amplification of genomic regions of difference.
نویسندگان
چکیده
Differentiation of members of the Mycobacterium tuberculosis complex by conventional mycobacteriological methods is time consuming, making surveillance of species-specific disease difficult. A two-step, multiplex polymerase chain reaction (PCR) method based on genomic regions of difference (RD1, RD1(mic), RD2(seal), RD4, RD9 and RD12) was developed for the differentiation of M. canettii, M. tuberculosis, M. africanum, M. microti, M. pinnipedii, M. caprae, M. bovis and M. bovis BCG. The size of the respective multiplex PCR amplification products corresponded to the presence of the different M. tuberculosis complex members. This method allows for rapid differentiation, making it suitable for routine laboratories and surveillance purposes.

Background and Objective: Identification of atypical mycobacterium (Non tuberculosis Mycobacterium NTM) is important because of the worldwide propagation of these organisms. Recently, molecular studies have identified the specific loci for mycobacterium species by DNA - finger printing methods, but these methods are time-consuming and expensive. In this study, in addition to hsp65 PCR-RFLP meth...

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...

A ligation-mediated PCR (LMPCR) method for the amplification of sequences flanking the IS6110 of the Mycobacterium tuberculosis complex has been developed. The method uses one primer specific for IS6110 and a second specific for a linker ligated to SalI-restricted genomic DNA. LMPCR is a rapid screening method, valuable for the fingerprinting of M. tuberculosis complex strains.

We evaluated a multiplex-PCR to differentiate Mycobacterium bovis from M. tuberculosis Complex (MTC) by one step amplification based on simultaneous detection of pncA 169 C > G change in M. bovis and the IS6110 present in MTC species. Our findings showed the proposed multiplex-PCR is a very useful tool for complementation in differentiating M. bovis from other cultured MTC species.
