One-step growth curve analysis of recombinant virus v545. Wild-type (ATCC 22122), recombinant (v545) and rescuant (v545R) viruses were used to infect confluent cell culture monolayers at an m.o.i. of 0.5 pfu/cell. After absorption for 1 h at 37°C, the cells were washed with media and a zero time point was harvested. The remainder of the sample was incubated at 37°C with additional time points taken at indicated times. The viral titer of each time point was determined by plaque titration assay on GPL cells.
