Growth kinetic curves of two wild-type BoHV-1 strains selected as parental strains in coinfection experiments. Data for intra- and extracellular growth kinetics of BoHV-1.1 (strain Ciney) and BoHV-1.2 (strain K22) were obtained after infection of MDBK cells at an MOI of 10. Titers, expressed as PFU, were recorded after 2, 5, 10, 15, 20, 25, 30, and 35 h postinfection (pi). The data presented are mean values ± 1.96 standard deviations of triplicates (α = 0.05).
