Abstract

A total of 274 Streptococcus dysgalactiae subsp. equisimilis isolates was analyzed by emm typing and by determining the organization of their mgrC loci. Three of the most frequent emm types were stG485.0 (45/274, 16.4%), stG6.1 (43/274, 15.7%), and stC839.0 (32/274, 11.7%), in decreasing order. The cpdB-positive mgrC locus appears to be predominant in some emm types.

Genetic organization of mgrC loci in S. dysgalactiae subsp. equisimilis NTUH-5518 (large type) and NTUH-7688 (small type). Genes are shown as arrows indicating the direction of transcription. The sequence of the 8-nucleotide repeat (GCAACTAA) in NTUH-7688 (one copy) and NTUH-5518 (two copies) is indicated. The dotted arrows indicate undetermined sequences of nrd and rel. The start (ATG) and stop (TAA) codons of cpdB are underlined.
