The absence (−) or presence of minor (+), moderate (++), or severe (+++) clinical signs of disease.
*All of these animals survived.
†Some of these animals survived, this indicates time to death for those that succumbed.
‡Data from the current study.
§Similar results to other rNiVM-wt infected ferrets in refs20,21.
One of five animals had minor, temporary neurological signs.
□The two animals that survived only demonstrated moderate neurological signs while those that succumbed demonstrated severe neurological signs.
