^aThese strains were previously described [15–17].

^bThese strains were previously described [18–20].

^cBovine strains from 2002–2003 have been previously described [13, 14].

^dFor 13 bovine strains from 2011–2013, the capsular genotype could not be determined. Part of these strains were previously described [13].

^eNew cps_BOV: new bovine capsular type.
