Invasion and Survival ofStreptococcus pyogenesin Eukaryotic Cells Correlates with the Source of the Clinical Isolates
1 Jun 1998
Abstract excerpt
The invasiveness of 96 group A streptococci (GAS) isolates (56 from throat or skin and 40 from blood) were analyzed. GAS invasion strongly correlated with the source of the isolates, whereas no correlation was observed with the Vir type. Isolates from throat or skin exhibited the highest invasion efficiency (57% were between 0.1% and 10%). In contrast, 77.5% of the blood isolates were noninvasive (efficiency...
