Group A beta-haemolytic streptococci (GAS) are Gram positive bacteria resembling chains ("streptos") of berries ("kokkus") that colonise mucus membranes and damaged skin. They are spread by skin contact and respiratory droplets. People of all ages are susceptible, but especially children, ...
Group A streptococcus was identified by 尾-haemolytic colonies with bacitracin and penicillin sensitivity, gram staining, catalase negativity and growth on crystal violet blood agar. In this study, 23 (17.2%) patients were positive for 尾-haemolytic streptococci. Among them, 12 (9%) were ...
A group beta haemolytic streptococci (AGBHS) are the major etiologic agent of acute tonsillopharyngitis and in such cases the classical therapeutic choice is penicillin. The aim of this study was to detect the penicillin susceptibility of AGBHS. We isolated 59 (%89) AGBHS and 7 (%11) non...
-haemolytic Streptococci Group A. Part 1. Overall strategy and synthesis ... The synthesis of a functionalised linear trisaccharide and its use in the synthesis of a branched tetrasaccharide corresponding to a portion of the cell-wall polysaccharide of the β-haemolytic Streptococci Group A is ...
OBJECTIVE: To determine the susceptibility of group A beta-hemolytic streptococci (GABHS) in the lower St Lawrence region, Quebec to different antibiotics, particularly macrolides, and to compare different antibiogram methods (disk diffusion, E-test and microdilution) and incubation atmospheres (ambient...
Two cases of severe infection due toStreptococcus pyogenes associated with a toxic-shock-like syndrome (TSLS) and also with serious soft-tissue infection a
The streptococci were identified as groupA streptococcus (GAS) in 11 patients and groupG streptococcus (GGS) in four patients. The patients with GGS infection were older than the patients with GAS infection, and all patients infected with GGS had predisposing comorbidities. Isolates from 13 ...
In throat culture developed a beta-haemolytic Group A streptococci. We started a treatment by oral penicillin and in this way we obtained an absolute resolution of her symptoms. Four weeks later she had a further episode of facial tics associated with a confirmed streptococcal throat infection. ...
This is stated to be the fifth case of human infection by group R haemolytic streptococci, and, as in the others, the report comes from Denmark. The patient, a butcher engaged in the slaughtering of pigs, was admitted with meningitis, and the organisms were cultured from the blood and cere...
There is continued interest in the development of oral beta-lactam compounds, which can be used clinically to treat various bacterial infections, particularly those caused by beta-haemolytic streptococci. Cefixime is a new orally active cephalosporin, with a broad spectrum of antibacterial activity, inc...
