dna sequencing is the most conclusive method for emm (m protein gene) typing of streptococcus pyogenes. this method is not a feasible approach in developing countries where streptococcal infection is widespread among adults and children. alternatively the pcr-rflp has the potential for rapid screening of different types of s. pyogenes. to document the emm type distribution of s. pyogenes in a g...

Streptococcus pyogenes, is an important human pathogen classified within the pyogenic group of streptococci, exclusively adapted to the human host. Our goal was to employ a comparative evolutionary approach to better understand the genomic events concomitant with S. pyogenes human adaptation. As part of ascertaining these events, we sequenced the genome of one of the potential sister species, t...
