  • a Alternative gene names are given in parentheses.

  • b The eftLSL sequence is published as readthrough fctA and srtC2; the calculated values in the table assume a stop codon at nucleotides 1033 to 1035 of eftLSL.

  • c From Table S1 in the supplemental material or http://www.mlst.net or determined in silico from whole genome sequences (GenBank accession numbers are listed in the legend to Fig. 1).

  • d Single-locus variant of ST16, the MLST genotype of the strain used for FCT region mapping (see Table S1 in the supplemental material).

  • e CS101 (Minnesota) is a laboratory derivative of B737 (Lancefield) (10); the right half of the FCT region sequence was determined using the CS101 culture, whereas for the right half, the B737 culture was used.

  • f TNT, T nontypeable.

  • g NA, not applicable.

  • h ND, not determined.
