  1. Details of the four previously sequenced weakly haemolytic B. hyodysenteriae are included for comparison. Farm of origin is given as an anonymised letter code, together with year of sampling, country of origin and haemolysis phenotype on TSA plates. Sequence type (ST), clone number, and plasmid type (PT) are indicated.
  2. aIsolate JR72 was weakly haemolytic on TSA plates, but strongly haemolytic in an in vitro haemolysis assay at high optical density (OD600 = 0.550 ± 0.05).
  3. Partial1 (adh not detected; alp: not detected; est3; gdh21; glpK40; pgm2; thi21).
  4. Partial2 (adh not detected; alp not detected; est29; gdh1; glpK10; pgm~22; thi38).
  5. Partial3 (adh2; alp not detected; est~11; gdh7; glpK8; pgm3; thi17).
  6. Partial4 (adh2; alp not detected; est5; gdh19; glpK~19; pgm3; thi3).
