The production of bacteriocin-like inhibition by certain strains of group A streptococci was
demonstrated during the growth of these organisms on solid nutrient media. Active …

To evaluate the role of putative group A streptococcal virulence factors in the initiation of skin
infections, we compared the adherence of a wild-type M49-protein skin-associated strain to …

S treptococcus anginosus and the closely related species S treptococcus constellatus and S
treptococcus intermedius, are primarily commensals of the mucosa. The true pathogenic …

Streptolysin S (SLS) is a potent cytolytic toxin and virulence factor that is produced by nearly
all Streptococcus pyogenes strains. Despite a 100-year history of research on this toxin, it …

The gene specifying the group A streptokinase (ska) gene was cloned from an M type 49
strain of Streptococcus pyogenes and shown to express in Escherichia coli. The nucleotide …

Group A streptococci incubated in human plasma can acquire a plasmin-like enzymatic
activity. This process involves at least two bacterial proteins and two human protein …

The cysteine protease of group A streptococci has been suggested to contribute to the
pathogenesis of invasive infection through degradation of host tissue, activation of the host …

The administration of high-dose clindamycin plus benzylpenicillin has been recommended
for the treatment of streptococcal toxic shock-like syndrome caused by Streptococcus …

The present study shows that active, self-splicing group II intron GBSi1 is located
downstream of the C5a-peptidase gene, scpB, in some group B streptococcus (GBS) …

The species specificities of plasminogen activation and binding of plasmin by pathogenic
group C streptococci isolated from humans, horses, and pigs were examined. Of 56 …
