چکیده انگلیسی
A PCR-linked reverse DNA hybridization method using two different specific rpoB DNA probes (Avp and Intp) of Mycobacterium avium and Mycobacterium intracellulare, respectively, were evaluated for the differentiation and identification of M. avium and M. intracellulare culture isolates. Among the 504 culture isolates tested by this method, 48 strains showed positive results for M. avium and 60 strains showed positive results for M. intracellulare. The other 396 culture isolates showed negative results for both M. avium and M. intracellulare. These results were consistent with those obtained from partial rpoB (306Â bp) sequence analysis and biochemical tests. The negative strains obtained by this DNA hybridization method were identified as M. tuberculosis (366 strains), M. peregrinum (11 strains), M. abscessus (9 strains), M. fortuitum (8 strains), and M. flavescens (2 strains) by rpoB DNA sequence analysis. Due to the high sensitive and specific result obtained by this assay, we suggest that this PCR-linked reverse DNA hybridization method using two different specific rpoB DNA probes of M. avium and M. intracellulare would be used for the rapid and precise method for differentiation and identification of M. avium and M. intracellulare.
