  1. nd: not defined.
  2. aAll strains were isolated from piglets of different herds, except 16-00654-02 and 16-00653-03 as well as 30T and 262/3, respectively.
  3. bAll strains were genotyped in the multiplex (MP) PCR and in the mrp variant PCR described by Silva et al. [19]. None of the strains was positive for the epf gene encoding EF.
  4. cSequences of MLST alleles of strains 30T and 262/3 have also been submitted to the MLST database, but the sequence type has not yet been assigned (id 1792 and 1793, respectively).
