  1. aAmino acid sequence identity (%) within each genospecies as compared to strains 12104 or T14V, respectively.
  2. bHemagglutination (HA) of neuraminidase treated human and untreated porcine, human and horse red blood cells by reciprocal dilutions of bacterial cell suspensions. The lowest dilution with visible HA is given. 0 marks no agglutination even at the highest dilution.
  3. ca and b denotes the two hemagglutination patterns observed in each genospecies.
  4. dCoaggregation properties as defined by coaggregation groups (COG) A to F [27]
