| Remarks: |
For the differentiation and identification of mycobacterial species, the rpoB gene, encoding the beta subunit of RNA polymerase, was investigated. rpoB DNAs (342 bp) were amplified from 44 reference strains of mycobacteria and clinical isolates (107 strains) by PCR. The nucleotide sequences were directly determined (306 bp) and aligned by using the multiple alignment algorithm in the MegAlign package (DNASTAR) and the MEGA program. A phylogenetic tree was constructed by the neighbor-joining method. Comparative sequence analysis of rpoB DNAs provided the basis for species differentiation within the genus Mycobacterium. Slowly and rapidly growing groups of mycobacteria were clearly separated, and each mycobacterial species was differentiated as a distinct entity in the phylogenetic tree. Pathogenic Mycobacterium kansasii was easily differentiated from nonpathogenic M. gastri; this differentiation cannot be achieved by using 16S rRNA gene (rDNA) sequences. By being grouped into species-specific clusters with low-level sequence divergence among strains of the same species, all of the clinical isolates could be easily identified. These results suggest that comparative sequence analysis of amplified rpoB DNAs can be used efficiently to identify clinical isolates of mycobacteria in parallel with traditional culture methods and as a supplement to 16S rDNA gene analysis. Furthermore, in the case of M. tuberculosis, rifampin resistance can be simultaneously determined. |

| Remarks: |
We describe a modified rRNA sequence analysis method which we used to determine the phylogenetic relationships among 58 species belonging to the genus Mycobacterium. We combined the sensitivity of the reverse transcriptase PCR for amplifying nanogram amounts of template rRNA material with the elevated extension temperatures used for the thermostable DNA polymerase from Thermus thermophilus. A 70 degrees C reverse transcription extension step permitted improved read-through of highly structured rRNA templates from members of the genus Mycobacterium, which have G+C contents of 66 to 71 mol%. The nucleic acid sequences of the amplified material were then determined by performing thermal cycle sequencing with alpha-33P-labeled primers, again with extension at 70 degrees C. Nonspecifically terminated bands were chased by using terminal deoxynucleotidyl transferase. Our method had a template requirement of nanogram amounts or less of purified RNA or 2,000 CFU of intact cells and had sufficient sensitivity so that lyophils obtained from the American Type Culture Collection could be used as source material. Sequences from a 250-nucleotide stretch of the 23S rRNA were aligned, and phylogenetic trees were evaluated by using the De Soete distance treeing algorithm and Rhodococcus bronchialis as the outgroup. Our 23S rRNA trees were compared with previously published 16S rRNA trees, including the comprehensive trees developed by the University of Illinois Ribosomal Database Project, and included 15 species not evaluated previously. Most of the groups were in general agreement and were consistent with relationships determined on the basis of biochemical characteristics, but some new relationships were also observed. |

| Remarks: |
The 16S rRNAs from nine rapidly growing Mycobacterium species were partially sequenced by using the dideoxynucleotide-terminated, primer extension method with cDNA generated by reverse transcriptase. The sequences were aligned with 47 16S rRNA or DNA sequences that represented 30 previously described and 5 undescribed species of the genus Mycobacterium, and a dendrogram was constructed by using equally weighted distance values. Our results confirmed the phylogenetic separation of the rapidly and slowly growing mycobacteria and showed that the majority of the slowly growing members of the genus represent the most recently evolved organisms. The 24 strains which represented 21 rapidly growing species constituted several sublines, which were defined by the following taxa: (i) Mycobacterium neoaurum and M. diernhoferi, (ii) M. gadium, (iii) the M. chubuense cluster, (iv) the M. fortuitum cluster, (v) M. kommossense, (vi) M. sphagni, (vii) M. fallax and M. chitae, (viii) M. aurum and M. vaccae, (ix) the M. flavescens cluster, and (x) M. chelonae subsp. abscessus. Our phylogenetic analysis confirmed the validity of the phenotypically defined species mentioned above, but our conclusions disagree with most of the conclusions about intrageneric relationships derived from numerical phenetic analyses. |

| Remarks: |
The determination of the amino acid sequence of quinolone resistance-determining regions (QRDRs) in the A and B subunits of DNA gyrase is the molecular test for the detection of fluoroquinolone resistance in mycobacteria. We looked to see if the assignment of mycobacterial species could be obtained simultaneously by analysis of the corresponding nucleotide sequences. PCR sequencing of gyrA and gyrB QRDRs was performed for 133 reference and clinical strains of 21 mycobacterial species commonly isolated in clinical laboratories. Nucleotide sequences of gyrA and gyrB QRDRs were species specific, regardless of fluoroquinolone susceptibility. |
