Susceptibility as defined in laboratory or exposure to M. cerebralis at vulnerable life stages. Score of 0-3 or S:

  • 0=resistant, no spores develop;
  • 1=partial resistance, clinical disease rare and develops only when exposed to very high parasite doses.
  • 2=susceptible, clinical disease common at high parasite doses, but greater resistance to disease at low doses.
  • 3=highly susceptible, clinical disease common.
  • S=susceptibility is unclear (conflicting reports, insufficient data, lack of M. cerebralis confirmation).

Data collated by Beth MacConnell and Dick Vincent and used with permission of the Whirling Disease Initiative, which funded the study.
