T-agglutination typing and M protein gene (emm) typing were determined on the isolates of Streptococcus pyogenes taken from patients in Osaka and neighboring districts during 1996-2000. A total of 701 isolates were classified to 15 kinds of T types and type untypable. In all isolates, T 12...

Based on pulsed-field gel electrophoresis typing, these strains were not the same (Table S1). Fewer spacers in erythromycin-resistant strains All of the emm12 and emm92 strains had two CRISPR loci; the number of spacers in one strain was calculated by adding the number of individual spacer...
The investigation was performed usingemmtyping, pulsed-field gel electrophoresis (PFGE) typing, superantigen profiling, and genome analysis. This enabled characterization of relatedness among the outbreak isolates and identification of the mobile genetic elements present. Among 57 patients with respiratory ...
