aNumber of isolates if more than 1.

bIsolates that were initially identified to subtype level and amplified using group-specific primers.

cIsolate that was resolved from subtype to serotype level in the second step of PCRSeqTyping.

d cpsB-PCR negative. All other isolates were both cpsB and lytA PCR positive.
