Boldface indicates spa types on which multilocus sequence typing analysis was performed (ST, sequence type).

a The strain spa typed as t008 had ST1411, a double locus variant of ST8 at the gmk and tpi locus.

b The strain spa typed as t021 had ST714, a single locus variant of ST30 at the arcc locus.

c The strain spa typed as t171 had ST720, a single locus variant of ST121 at the yqil locus.
