title: Variation of virus replication in primary bovine kidney cell cultures derived from 68 three-day-old calves.
abstract: Primary kidney cell cultures were prepared from 68 three-day-old calves. Complete monolayers of these cultures were infected separately with viral diarrhea, infectious bovine rhinotracheitis, parainfluenza, and adenovirus 7 viruses. The yield of virus from all infected cultures was calculated by plaque titer assay after 2 to 4 days' incubation. The variation of virus yield was substantial between individual cultures.
