Figure 3. Blepharitis and corneal scarring (CS) following ocular infection. Three weeks after the third vaccination, STAT4^−/− and BALB/c mice were infected infected ocularly with Herpes simplex virus type 1 neurovirulent strain McKrae. Blepharitis was measured 7 days after ocular infection based on 20 eyes, while CS was measured 28 days after ocular infection from surviving mice listed in Table 2. The error bars indicate the standard errors. A: Graph A shows blepharitis on day 7 post-infection. B: Graph B shows CS on day 28 post-infection. The p values were calculated from the Student t test.
