Blood may be collected for virus isolation in tissue culture or antibody detection. For
virus isolation whole unclotted blood is required. For antibody detection serum decanted
from clotted whole blood is required.
• in animals which are suspected to be in the late phase of the
incubation period, possibly having raised body temperatures
(pyrexia) or reduced milk yield in dairy cows. Virus isolation from blood is unlikely to be successful if ageing of lesions suggests that
disease has been present for more than 3 to 4 days. Blood is not the sample of choice if
fresh vesicular material is present.
