Invasive Streptococcus anginosus group infection—does the species predict the outcome?

Phenotypic differentiation of Streptococcus intermedius, Streptococcus constellatus, and Streptococcus anginosus strains within the "Streptococcus milleri group".

A biochemical scheme was developed by which strains of Streptococcus constellatus, Streptococcus intermedius, and Streptococcus anginosus can reliably be distinguished from within the "Streptococcus milleri group." Strains identified as S. intermedius were differentiated by the ability to produce detectable levels of alpha-glucosidase, beta-galactosidase, beta-D-fucosidase, beta-N-acetylgalacto...

Streptococcus anginosus ("Streptococcus milleri"): the unrecognized pathogen.

"Streptococcus milleri" is an unofficial name that has been applied to a group of streptococci which, although basically similar, show various hemolytic, serological, and physiological characteristics. The species name Streptococcus anginosus has recently been recognized as the approved name for these organisms. Streptococci known as "S. milleri" have been implicated as etiologic agents in a va...

Streptococcus anginosus group - cause of endocarditis and abscesses (S. milleri)

Classification, nomenclature and identification of the Streptococcus anginosus group (SAG) have been historically problematic and unreliable, mainly due to variability in bacteriological characteristics and clinical presentations. This group was first discovered in 1956 by Guthof, in reference to non-hemolytic streptococcal lassification, nomenclature and identification of the Streptococcus ang...

Streptococcus intermedius, Streptococcus constellatus, and Streptococcus anginosus (the Streptococcus milleri group): association with different body sites and clinical infections.

The associations of Streptococcus intermedius, S. constellatus, and S. anginosus (the three species of the S. milleri group) with clinical infections and sites of isolation were investigated by using a simple biochemical scheme to identify a collection of 153 clinical isolates. S. intermedius was associated with abscesses of the brain and liver, while both S. anginosus and S. constellatus were ...
