Relatedness of ‘Streptococcus milleri’ with Streptococcus anginosus and Streptococcus constellatus
Systematic and Applied Microbiology, 1984Summary Thirteen selected strains of ‘S. milleri’ were compared with the type strains of S. anginosus, S. constellatus and S. intermedius . They contain the same peptidoglycan type (Lys-Ala 1-3 ), their DNA base composition is in the range of 36 to 39 mol% G+C and all strains hydrolyze arginine, salicin and esculin and do not produce acid from ...

Publisher Summary Streptococci are Gram-positive cocci that divide in one plane only and so are arranged in chains of varying lengths. Some strains grow poorly on simple media and might be pathogenic to man and animals. Streptococci do not exhibit marked metabolic activities.

Seminars in Pediatric Infectious Diseases, 2006
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 ...

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).

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.

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 infantarius sp. nov. Related to Streptococcus bovis and Streptococcus equinus
1997Streptococcus bovis and S. equinus are intestinal bacteria, formerly called non-enterococcal group D streptococci, that are frequently isolated from human and animal specimens. These two species were first delineated according to epidemiological and biochemical characteristics, and then two different biotypes of S. bovis were described. The distinction

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

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.

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.
