متن کاملNew phenotypic typing scheme for group B streptococci.
AIMS To develop a new typing system for group B streptococci based on 35S-methionine-labelled protein profiles of bacterial proteins. METHODS 377 clinical isolates of group B streptococci were examined by incorporation of 35S-methionine into bacterial proteins under strict anaerobic conditions. After sodium dodecylsulphate-polyacrylamide gel electrophoresis, autoradiography was performed. The...
متن کاملcapsular serotype and antibiotic resistance of group b streptococci isolated from pregnant women in ardabil, iran.
background and objectives: group b streptococci (gbs) is a major cause of neonatal and maternal infections. the aim of this study was to determine the serotype distribution and antibiotic resistance profile of gbs strains isolated from pregnant women in ardabil. materials and methods: antibiotic resistance of 56 gbs isolates was investigated using e-test strips and disk-diffusion method. seroty...
متن کاملDetection and identification of group B streptococci by use of pigment production.
Pigment production by group B streptococci (GBS) is a useful test for identification of the organisms. The test is positive in 99.5% of beta-haemolytic strains. No false-positives are noted. Non-haemolytic strains do not produce pigment. Islam's media less agar can be used as a one-step broth detector of GBS in mixed cultures. This may have application for the detection of GBS in women in labou...
متن کاملEvaluation of rapid methods of identifying group B streptococci.
Rapid methods of identifying Lancefield group B streptococci were compared to the standard Fuller's extraction method. Such tests as sodium hippurate hydrolysis, bile tolerance, aesculin hydrolysis, pyruvate fermentation, Camp factor, pigmentation, and bacitracin haemolysis were tested on both routine clinical specimens and National Collection of Type Culture strains. The results show that pigm...
