Partial recN gene sequencing: a new tool for identification and phylogeny within the genus Streptococcus

31 Oct 2009

Abstract excerpt

Partial sequences of the recN gene (1249 bp), which encodes a recombination and repair protein, were analysed to determine the phylogenetic relationship and identification of streptococci. The partial sequences presented interspecies nucleotide similarity of 56.4-98.2 % and intersubspecies similarity of 89.8-98 %. The mean DNA sequence similarity of recN gene sequences (66.6 %) was found to be lower than those of...
