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 ...

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

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 ...

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 ...

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.

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.

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
