  • a Gonococcal isolates (with the exception of CDC77-124615 and CDC84-060418) were obtained from the indicated sources, and the MICs of penicillin for these strains were determined as described in Materials and Methods. Serovars of CDC77-124615 and CDC84-060418 were determined from the sequences of their porin genes (19).

  • b Only genomic DNA was available from these strains.
