BVD diagnostics and epidemiology

BVD is an exotic disease in Denmark and the present surveillance do detect occasional relapses of BVDV. In cooperation with the Danish Dairy Board we are optimising the diagnostic tools to have a very high sensitivity and therefore the general uses of BVD PCR for analysis of suspicions have now been incorporated in the Danish BVDV directive. Through the campaign we now have some very good tools for detection of PI animals in infected herds.

When there are relapses of BVDV in cattle herds the sample will be analysed in a high throughput system using the new MagnaPure robot, this will be a good model for CSFV high throughput analysis.
Bulk milk analysis is based on herd sizes up to 100 lactating cows, we now experience an increase in the herd size and therefore we need to reconsider the use of bulk milk or the sensitivity of this method.
