As part of the evaluation and management of pharyngitis in a college health service, we use rapid group A Streptococcus antigen testing (Clearview Strep A exact II Dipstick) with "back up" culture of the negative swabs. Because of the association of non-group A Streptococcus organisms in ...
organisms. Although no strict separation can be made, group B streptococcus predominantly threatens neonates following vertical transmission from the birth canal of colonized parturients, their intestinal tract serving as an endogenous reservoir. As shown by history, group A streptococcus predominantly is...
Integrated whole-genome sequencing and temporospatial analysis of a continuing Group A Streptococcus epidemic 601 type emm59 Group A Streptococcus (GAS) organisms responsible for an ongoing epidemic of invasive infections in Canada and some of the United States. ...

The streptococcus can be present on healthy skin for at least a week before lesions appear. S pyogenes is primarily spread through person-to-person transmission, although foodborne and waterborne outbreaks have been documented. Neither spread of organisms by fomites nor transmission from animals (eg,...
Streptococcus pyogenes (Group A Streptococcus, GAS) is a human-restricted pathogen that causes a wide variety of human diseases ranging from commonly mild superficial infections of the pharynx and skin to life-threatening invasive diseases such as necrotizing fasciitis1,2. GAS organisms are also ...
Streptococcus pyogenes (Group A Streptococci) Group A streptococci are the major cause of streptococcal infections in human beings. The organisms colonize oral mucosa and skin and cause a wide spectrum of pyogenic infections, such as tonsillitis, pharyngitis, scarlet fever, and skin i...
Demonstration of Streptococcus mutans with a cell wall polysaccharide specific to a new serotype, k, in the human oral cavity. Streptococcus mutans organisms are occasionally isolated from the blood of patients with infective endocarditis, though the mechanisms of invasion and surv... K Nakano,R Nom...
The M protein radiating from the surface of group A streptococci is the principal virulence factor of these organisms. Streptococci lacking M protein are readily opsonized by complement through the alternate pathway (1) and as a result are rapidly ingest

Group B Streptococcus, also known as Streptococcus agalactiae, was once considered a pathogen of only domestic animals, causing mastitis in cows. S agalactiae is now best known as a cause of postpartum infection and as the most common cause of neonatal s
