Rostral bioluminescence derives from the brain and trigeminal ganglia. Pups (n = 3) were challenged with 1 × 105 PFU of luciferase-expressing HSV-1, then imaged following i.p. administration of 20 ul of luciferin (15 mg/ml). (A) Bioluminescence of pup imaged, and immediately sacrificed and dissected on DPI 2. (B and C) Bioluminescence of pups imaged, and immediately sacrificed and dissected on DPI 4. DPI, days postinfection.
