Comparison between rpoB and 16S rRNA gene sequencing for molecular identification of 168 clinical isolates of Corynebacterium

Abstract

Higher proportions (91%) of 168 corynebacterial isolates were positively identified by partial rpoB gene determination than by that based on 16S rRNA gene sequences. This method is thus a simple, molecular-analysis-based method for identification of corynebacteria, but it should be used in conjunction with other tests for definitive identification.

Dendrogram representing phylogenetic relationships of Corynebacterium type species and not-well-classified isolates by the neighbor-joining method. The tree was derived by alignment of concatenated 16S rRNA and rpoB genes sequences. The sizes of the 16S rRNA and rpoB gene sequences aligned ranged from 1224 to 1248 and 425 to 443 bp, respectively. The support of each branch, as determined from 1,000 bootstrap samples, is indicated by the value at each node (in percent). Only bootstrap values of ≥70% are given. Mycobacterium smegmatis was taken as the outgroup.
