Serotyping 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...

متن کاملSerotyping Streptococcus pneumoniae by multiplex PCR.
The capsule is a major virulence factor of pneumococci, and it was shown that some capsular variants are associated with antimicrobial resistance and certain types of disease. Moreover, pneumococcal capsular typing has received renewed interest since the availability of conjugate vaccines, which include serotypes frequently associated with pediatric disease. Our aim was to develop a simple, rel...
متن کاملIdentification of Streptococcus pneumoniae by the Phadebact coagglutination test.
The Phadebact Pneumococcus Test is a coagglutination slide test for the serological identification of Streptococcus pneumoniae. Of 200 alpha-hemolytic streptococcal isolates, coagglutination test results agreed with those of optochin susceptibility and bile solubility in 189 cases, 105 of which were identified as S. pneumoniae by all three methods. The Phadebact test was 100% (113 of 113) sensi...
متن کاملMolecular Detection and Serotyping of Streptococcus Pneumoniae in Children with Suspected Meningitis in Northeast Iran
Background: To date, more than 90 Streptococcus pneumoniae (S. pneumoniae) capsular serotypes are known. The prevalence of these serotypes varies according to the geographical area and the regional vaccination program. Due to the lack of regular vaccination programs for S. pneumoniae in developing countries, serotyping of the prevalent isolates is useful in selecting the correct vaccine. The pr...
