Detection of latent virus in TG of immunized mice 30 days after ocular challenge^a

Vaccine	No. of TG with infectious virus/total no. of TG (%)
vP35	8/40 (20)
vP40	12/40 (30)
vIL-4	13/40 (32)
dbl-p	20/40 (50)
KOS	11/40 (27)
Mock	8/8 (100)

^aAt 30 days after ocular challenge of surviving immunized and mock-immunized mice, each individual mouse TG was examined by explant cocultivation with RS cells for the presence of latent virus as described in Materials and Methods. Each value represents the number of TG with infectious virus per total TG from two experiments. P values were determined by using the Fisher exact test. P (vP35 versus vP40, vIL-4, or KOS) = 0.4; P (vP35 versus dbl-p) = 0.009; P (vaccinated versus mock) < 0.01.
