title: Identification of newly described Streptococcus pneumoniae serotype 6D by use of the Quellung reaction and PCR.
abstract: We tested 121 pneumococcal serogroup 6 isolates (including 30 serotype 6C and 24 serotype 6D isolates) by serotype-specific PCR and the Quellung reaction, using "old" and "new" pool B, factor 6b, and new factor 6d antisera. In combination with group B and other factor antisera, factor 6d antiserum can reliably identify the newly described serotype 6D.
