Capillary electrophoretic restriction fragment length polymorphism patterns for the Mycobacterial hsp65 gene.
PCR-restriction fragment length polymorphism (RFLP) analysis is a nonprobe method for the rapid identification of Mycobacterium species. We demonstrate the separation of DNA or restriction fragments digested from the mycobacterial gene encoding the 65-kDa heat shock protein (hsp65) by capillary electrophoresis (CE). By using a pair of unlabeled primers, Tb11 and Tb12, and only one restriction e...
متن کاملIdentification of 54 mycobacterial species by PCR-restriction fragment length polymorphism analysis of the hsp65 gene.
A total of 121 reference and clinical strains of both slowly and rapidly growing mycobacteria belonging to 54 species were studied for restriction fragment length polymorphism of a PCR-amplified 439-bp segment of the gene encoding the 65-kDa heat shock protein. Restriction digests were separated by 10% polyacrylamide gel electrophoresis (PAGE). By including a size standard in each sample, the r...
متن کاملNucleotide sequence comparison of the mycobacterial dnaJ gene and PCR-restriction fragment length polymorphism analysis for identification of mycobacterial species.
We recently reported a genus-specific PCR for the mycobacterial dnaJ gene. In the present study, we have determined the nucleotide sequences of the dnaJ gene from 19 mycobacterial species (Mycobacterium tuberculosis, M. bovis, M. bovis BCG, M. africanum, M. microti, M. marinum, M. kansasii, M. gastri, M. simiae, M. scrofulaceum, M. szulgai, M. gordonae, M. avium, M. intracellulare, M. xenopi, M...
متن کاملRestriction Fragment Length Polymorphism (RFLP)
Restriction Fragment Length Polymorphism (RFLP) is a technique in which organisms may be differentiated by analysis of patterns derived from cleavage of their DNA. If two organisms differ in the distance between sites of cleavage of a particular restriction endonuclease, the length of the fragments produced will differ when the DNA is digested with a restriction enzyme. The similarity of the pa...
متن کاملApplication of PCR-based restriction fragment length polymorphism for the identification of mycobacterial isolates.
BACKGROUND AND OBJECTIVE Conventional identification of mycobacteria is achieved by standard biochemical tests that are time consuming, laborious and is not always conclusive. This study was thus undertaken to standardize a simple, rapid and cost-effective polymerase chain reaction based restriction fragment length polymorphism (PCR-RFLP) using primers coding for the 16S - 23S rRNA spacer regio...
