The amount of Evans blue staining in the mice brain significantly increased at 3 weeks post-infection compared to those of uninfected mice ( p  = 0.03). Dexamethasone administration for 2 weeks (7th–21st day post-infection, group 3W + D) significantly decreased the intensity of Evans blue staining compared to those of mice at 3 weeks post-infection, which had the most serious damage to the blood-brain barrier (p = 0.025).
