^aoriginally published by Kielstein and Rapp-Gabrielson (1992) and adapted by Zehr and Tabatabai (2011).
^bH, Highly virulent, death of pig within 96 h post-inoculation; L+, Polyserositis and arthritis at necropsy; L-, Mild clinical symptoms; A, Avirulent, no clinical symptoms at necropsy as described by Kielstein and Rapp-Gabrielson (1992).
^cH367 (serovar 10) is a field strain with the same characteristics as the original H555. Reference strain H555 was lost during culture passage prior to our acquisition of the reference strains above.
