Streptococcus pyogenes genome exposed

Streptococcus pyogenes ( Group A Streptococcus )

Group A streptococcus (GAS) is synonymous with Streptococcus pyogenes, the only species within this group of β-hemolytic streptococci. GAS is one of the leading pathogenic bacteria that infects children and adolescents, and is associated with a wide spectrum of infections and disease states. Worldwide, there are estimated to be >600 million cases of GAS pharyngitis (“strep throat”) and >100 mil...

Draft Genome Sequence of Streptococcus pyogenes Strain M3KCL

We present here the draft genome sequence of Streptococcus pyogenes strain M3KCL. The assembly contains 1,864,059 bp in 60 contigs. This strain is an M3 strain close to MGAS315 but produces SpeB. It was isolated from the blood of a human patient with an invasive infection in 2009.

Complete genome sequence of an M1 strain of Streptococcus pyogenes.

The 1,852,442-bp sequence of an M1 strain of Streptococcus pyogenes, a Gram-positive pathogen, has been determined and contains 1,752 predicted protein-encoding genes. Approximately one-third of these genes have no identifiable function, with the remainder falling into previously characterized categories of known microbial function. Consistent with the observation that S. pyogenes is responsibl...

Studies on Streptococcus Pyogenes

Electron microscopic observations of Streptococcus pyogenes (strain S43, type 6) treated with trypsin and cetyltrimethylammonium bromide (Cetab) are presented. The concentration of trypsin necessary to remove the M protein antigen was shown to bring about a partial digestion of the cells. The cell protoplasm and protoplasmic membrane were affected. No microscopic changes appeared in the cell wa...
