¹ S. suis isolates were described in de Greeff et al. [14].

²*indicates an higher molecular weight form of MRP; s indicates a lower molecular weight form of MRP.

³*indicates an higher molecular weight form of EF.

⁴All isolates were genotyped using Comparative Genome Hybridization (CGH) [14].

⁵This isolate belongs to clonal complex 1.

“-” indicates absence of the protein; “+” indicates presence of the protein.
