Data for papG alleles, sfa and/or foc, afa and/or dra, hly, iut, bma, and nfa are reported elsewhere (20, 45). One strain within cluster III fell outside the four subclusters. Thus, subclusters A to D account for only 118 strains, whereas the total in cluster III is 119 strains.
b
P < 0.05, indicated group versus all other strains.
c
P ≤ 0.01, indicated group versus all other strains.
d
P ≤ 0.001, indicated group versus all other strains.
e
Strains were considered K2 positive if positive for kpsMIITII by blot but not PCR.
