Identification of group B streptococci by immunofluorescence staining.
Gamma globulin fractions of rabbit antisera prepared with whole cell vaccines of group B types Ia, Ib, II, and III and labeled with fluorescein isothiocyanate stained group B streptococci type specifically. Type Ic cells, which contain the Ia polysaccharide antigen of type Ia and the Ic protein antigen of type Ib, were specifically stained by both Ia and Ib conjugates. A group B conjugate pool ...
متن کاملGrouping and detection of group B streptococci by immunofluorescence.
Forty-nine clinical isolates of group B streptococci (GBS) were correctly grouped from broth culture by the Fluoro-Kit immunofluorescence test. A further 82 beta-haemolytic streptococci of groups A, C, D, F, and G were tested and gave no cross-reactions. The test was simple to perform and gave clear results. The Fluoro-Kit reagents, however, failed to detect GBS in 21 (51%) of 41 smears of rect...
متن کاملClinical application of immunofluorescence. 3. Identification of Lancefield group B streptococci.
The identification of Lancefield group B streptococci with immunofluorescence was studied after significant differences between the precipitin and immunofluorescent results were noted. It was found that strains of group B streptococci, unlike groups A, C, and G streptococci, do not reliably react with a fluorescein isothiocyanate-labeled conjugate that contains antibodies mainly against C polys...

15 صفحه اولRAPID IDENTIFICATION OF GROUP A STREPTOCOCCI BY PYRROLIDONYL-β-APHTHYLAMIDE HYDROLYSIS
In a clinical trial a new pyrrolidonyl-β-naphthylamide (PYR) hydrolysis test was compared with the bacitracin disk susceptibility test for accuracy in the presumptive identification of group A streptococci (GAS). Among 128 isolates of beta-hemolytic streptococci 93 group A isolates were found. The sensitivity of the PYR and bacitracin tests were similar (98.9%), but the bacitracin test had ...
