Abstract

Although 16S rRNA gene sequences are conventionally analysed in bacterial systematics, their resolution is not sufficient for species identification. Multilocus sequence analysis (MLSA) is a powerful method for species identification as well as the elucidation of phylogenetic relationships in the genus . Gene sequences of and are generally used in MLSA for species. This study aims to evaluate the sequence analysis of one gene instead of all five genes to be employed for species identification. The resolution of gene sequences was not necessarily able to distinguish closely related species. In contrast, gene sequence similarities correlated to the MLSA-based evolutionary distances, especially among closely related strains. A pairwise similarity of 97.9 % in gene sequences was proposed as the threshold for species delineation based on the feasibility examined using strain pairs that shared >99.93 % pairwise 16S rRNA gene sequence similarities. Resequencing the five housekeeping genes followed by MLSA suggested that and are synonyms of .
