  • a Each fla genotype designation comprises the HinfI and DdeI profile numbers, in that order. P and L refer to the Penner serotype and the Lior serotype, respectively.

  • b Numbers were assigned arbitrarily to the PFGE fingerprints obtained after digestion with the following restriction enzymes: SmaI (S), BamHI (B), and KpnI (K). S0 indicates samples that were not digested with SmaI.

  • c ND, not done.
