*ND, not done; NT, nontypeable.
†We performed PCR capsular typing using the oligonucleotides given in Technical Appendix Table). Results were interpreted as done previously (7): isolates positive for PCR ABC, A, and B were typed as A, isolates positive for PCR ABC and B were typed as B, and isolates positive for PCR ABC and C were typed as C.
‡Western blot analyses on polysaccharidic structures were performed by using specific polyclonal rabbit antisera.
