Validation of Factor 6d Antiserum for Serotyping Streptococcus pneumoniae Serotype 6C

摘要

Factor 6d antiserum reacts with the new Streptococcus pneumoniae serotype 6C. Serogroup 6 isolates, consisting of 49 6A, 42 6B and 98 6C strains from the United States and Israel, serotyped in parallel by PCR and capsular swelling methods, were all identified correctly. The new factor 6d antiserum accurately identifies serotype 6C.
