*ID, identification; MLST, multilocus sequence typing. †Not previously described. ‡The samples were collected for screening of S. equi subsp. equi, but S. equi subsp. zooepidemicus was identified. §Co-infection with Pasteurella sp. and S. suis. ¶Recorded in the PubMLST database: 8 (arcC)–52 (nrdE)–2 (proS)–14 (spi)–1 (tdk)–22 (tpi)–n/a (yqiL).
