Confirmation of psaA in All 90 Serotypes of Streptococcus pneumoniae by PCR and Potential of This Assay for Identification and Diagnosis
1 Jan 2000
Abstract excerpt
The gene encoding the pneumococcal surface adhesin A (PsaA) protein, psaA, was confirmed in all Streptococcus pneumoniae serotypes by a newly developed PCR (psaA PCR) assay. Eighty-nine of the 90 serotypes amplified produced an 838-bp fragment; the exception was a serotype 16F strain acquired from the American Type Culture Collection (ATCC). Analysis of 20 additional 16F strains from the United States and Brazil...
