Figure 2. Expression of herpes simplex virus 1 proteins in the trigeminal ganglia of BALB/c mice. Five days after virus inoculation, murine trigeminal ganglia (TG) were isolated, formalin fixed, paraffin embedded, sectioned and stained with a rabbit antiserum raised against herpes simplex virus 1 (HSV-1). A lack of brown staining indicates lack of HSV-1 proteins. TG tissue 5 days after KOS-tk12 inoculation is shown in panel A and TG 5 days after KOS-Rid1-tk12 inoculation is shown in panel B Uninfected TG section is shown in panel C HSV-1 infected corneas were used as positive control (Figure 1). Representative pictures are shown.
