Abstract
SUMMARY
Bovine parvovirus readily produced plaques when inoculated into 60% confluent, actively growing bovine embryonic lung cells. Incorporation of DEAE-dextran, MgCl2 and DMSO in the agarose overlay medium was found to improve plaque production, especially with the latter chemical. In contrast, protamine sulphate inhibited plaque development. It was found that plaque titration and plaque inhibition tests could be conveniently carried out in 24-well cell culture plates, using an agarose overlay containing DMSO, DEAE-dextran and foetal calf serum. The procedures were highly sensitive, when compared with other established techniques.
