a

Group categories based on animal's rabies virus neutralizing antibody level at baseline: negative: <0.05 IU/mL, low: ≥0.05–0.11 IU/mL, medium: >0.11–<0.5 IU/mL, high: ≥0.5 IU/mL.

b

IU/mL = international units/milliliter.

c

Animal blood sampling time periods: baseline = day animal captured in the wild, challenge = day animal challenged with rabies virus.

d

Survival status of animals: Y= survived rabies challenge, N = developed signs consistent with rabies and was euthanized. All euthanized animals were confirmed rabid by direct fluorescent antibody.
