FIG. 1.
Kinetics of EHV-1 and RacL11 growth in the lungs of CBA mice. CBA mice were infected i.n. with 2 × 106 PFU of KyA or 1.5 × 106 PFU of RacL11 and on days 2 through 6; the lungs were removed and homogenized in a 3-ml tissue grinder. The amount of infectious EHV-1 was determined by standard plaque titration on RK monolayers as described in Materials and Methods. Each dot represents the log PFU per lung determined from a single mouse. The horizontal bars represent the mean log PFU per experimental group.
