Bacteremia Caused by Group G Streptococci, Taiwan
A retrospective observational study in Taiwan, 1998-2004, identified 92 patients with group G streptococcal bacteremia; 86 had Streptococcus dysgalactiae subspecies equisimilis. The most common diagnosis was cellulitis (48 cases), followed by primary bacteremia (34 cases). Infection recurred in 9 patients. Mortality rate was low (3.3%); resistance to quinupristin-dalfopristin was high.
متن کاملBacteriocine Production by Group a Streptococci
I t has been known for many years t ha t some strains of Escherichia coli, Bacillus megaterium, and Group D streptococci secrete substances called colicines, or bacteriocines, which inhibi t the growth of o ther strains of closely related microorganisms (1-6). In 1949 Sherwood and his coworkers (7) reported observations on the inhibitory action of certain strains of be ta hemolyt ic streptococc...
متن کاملRegulation of lactose fermentation in group N streptococci.
Group N streptococci, which have the lactose phosphoenolpyruvate (PEP)-dependent phosphotransferase system (PTS) and phospho-beta-d-galactosidase (beta-Pgal), grew rapidly on lactose and converted more than 90% of the sugar to l-lactate. In contrast, Streptococcus lactis 7962, which does not have a beta-Pgal, grew slowly on lactose and converted only 15% of the sugar to l-lactate. With glucose ...
متن کاملIdentification of a peptide from mammal albumins responsible for enhanced pigment production by group B streptococci.
The peptide from peptones responsible for enhanced pigment production by Streptococcus agalactiae in culture media has been isolated from a peptic digest of human albumin and has been identified as Ile-Ala-Arg-Arg-His-Pro-Tyr-Phe. The related heptapeptide lacking the N-terminal Ile also had pigment-enhancing activity. A sequence similarity search showed that these sequences are present only in ...
متن کاملSerious infection caused by group C streptococci.
Group C streptococci commonly cause infection in animals but only occasionally give rise to severe infection in man. We report here three cases of serious human infection due to this organism and discuss its pathogenicity in relation to the clinical manifestations of the disease.
