  1. aN/A: not applicable; at this stage serotype 1/2 strains are presumptively assigned to serotype 2 and serotype 14 strains are presumptively assigned to serotype 1
  2. bAll six serotype 8 strains were assigned to serotype 8 by our pipeline after resequencing of the genome of one serotype isolate whose genome had originally been sequenced at low read coverage due to technical issues during genomic libraries preparation
