Collection of samples

Blood

 

Blood

 

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.

Collection of blood for virus isolation is useful:

    • 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.

    • in sheep with minimal or no vesicular lesions but where FMD is suspected due to either lameness in several animals or pyrexia.

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.
