*Data indicate the sum of clinical scores, as follows: ocular and nasal discharge (0 = no discharge, 0.5 = serous, 1.0 = mild mucopurulent, 2.0 = severe mucopurulent); cough (0 = absent, 0.5 = mild, 1.0 = moderate, 1.5 = persistent, 2.0 = severe with choking or retching); sneezing, dyspnea, and depression (0 = absent, 2 = present); and body temperature (0 = <39.58°C, 2 = ≥39.58°C). Shading indicates days on which some animals had a clinical score >1, showing the shift between the 2 cohorts.
†Euthanized on the day indicated.
