Group A streptococci (GAS) are gram positive cocci that can be divided into more than 100 M-serotypes or emm types based on their M proteins. Their virulence is related directly to the M protein on the cell surface that inhibits phagocytosis. Although it is more commonly thought of in the context of causing clinical illness, Streptococcus pyogenes can ...

Pediatrics In Review, 2018
Group A Streptococcus (GAS) infections are highly prevalent, and account for major morbidity and mortality worldwide, from both primary infections and subsequent complications. On the basis of strong research evidence, all children older than 3 years who present with pharyngitis without features that strongly suggest a viral etiology should undergo ...

Archives of Dermatology, 1992
In this issue of theArchives, Telfer et al 1 examine the role of Streptococcus in psoriasis with specific reference to serologic subtypes. This study fails to show that patients whose psoriasis was triggered or aggravated by streptococci harbored specific subtypes (as has been demonstrated for patients with acute glomerulonephritis and those with acute

Invertase activity in Streptococcus mutans and Streptococcus sanguis
Archives of Oral Biology, 1973Abstract Toluene treatment of intact cells revealed invertase-like activity in Streptococcus mutans K1-R (cariogenic) and in Streptococcus sanguis 903–1600 (noncariogenic). The activity was identified as a β- d -fructofuranoside fructohydrolase (invertase; EC.

Streptococcus castoreus, an uncommon group A Streptococcus in beavers
Antonie van Leeuwenhoek, 2019Streptococcus castoreus is a rarely encountered beta-haemolytic group A Streptococcus with high tropism for the beaver as host. Based on 27 field isolates under study, evidence strongly suggests that S. castoreus behaves as an opportunistic pathogen in beavers.

Streptococcus anginosus (“Streptococcus milleri”)
Clinical Microbiology Newsletter, 1988The name "Streptococcus milleri" has been used mainly by British and European microbiologists to describe a heterogeneous group of streptococci known by a variety of species names in the United States. Recently a proposal was made to combine these various types of streptococci into a single species named Streptococcus anginosus (8).

Extracellular invertase in Streptococcus mutans and Streptococcus salivarius
Life Sciences, 1974Summary Cultures of representative oral streptococci were fractionated and assayed for glycosyltransferases and invertase. Considerable extracellular invertase activity was found in five Streptococcus mutans strains and one Streptococcus salivarius strain. For example, in cultures of S.

Group B Streptococcus (Streptococcus agalactiae)
2018Group B Streptococcus (GBS) is a leading cause of early neonatal infection and neonatal mortality, with long-term adverse neurodevelopmental outcomes in up to 50% of survivors of GBS meningitis. GBS has a likely underappreciated role in causing preterm birth and stillbirth.

Transition Metal Homeostasis in Streptococcus pyogenes and Streptococcus pneumoniae
2017Trace metals such as Fe, Mn, Zn and Cu are essential for various biological functions including proper innate immune function. The host immune system has complicated and coordinated mechanisms in place to either starve and/or overload invading pathogens with various metals to combat the infection. Here, we discuss the roles of Fe, Mn and Zn in terms of
