Lim group B Strep Broth and coagglutination for rapid identification of group B streptococci in preterm pregnant women.
A total of 147 preterm pregnant women at Orlando Regional Medical Center were screened for group B streptococci by using Lim Group B Strep Broth (GIBCO Laboratories, Madison, Wis.) and the Phadebact Strep B Test (Pharmacia Diagnostics, Piscataway, N.J.). Test results were available within 20 h of culture and, in the case of heavily colonized women, within 5 h. This procedure is useful in rapid ...
متن کاملRapid slide coagglutination test for identifying and typing group B streptococci.
A Cowan I strain of Staphylococcus aureus was labeled with either group B streptococcal grouping or typing antiserum. These antibody-labeled reagent cells (ARC) were used in a slide coagglutination test to identify and type group B streptococci from blood agar plates. All streptococci were also identified by the standard Lancefield capillary precipitin test. In a blind study, all 141 group B st...
متن کاملSerological grouping of streptococci by a slide coagglutination method.
A new method for the serological grouping of streptococci by coagglutination with specific antibodies absorbed to protein A-containing staphylococci has been assessed. A total of 242 strains of streptococci, including beta-haemolytic streptococci of groups A, B, C, F, and G, Streptococcus pneumoniae and Strep. faecalis were studied. All streptococci of groups A, B, C, and G, groupable by standa...
متن کاملModified method for serological identification of group B streptococci.
Extracts from 10- and 40-ml cultures compared favorably for serological identification of group B streptococci. Typing by gel diffusion proved reliable and efficient. These modifications save time, media, and antisera.
متن کاملSerotyping of Streptococcus pneumoniae strains by coagglutination.
The coagglutination test, which uses staphylococcal protein A, for serotyping strains of Streptococcus pneumoniae, was extended to include serotyping within serogroups. Serotyping was performed with "factor sera" prepared in the laboratory. Fifty one strains of S pneumoniae, which belonged to one of the seven serogroups included in the 14 valent vaccine formulation, were tested, and no inconsis...
