    Abstract:
    Forty-five Swiss albino mice were inoculated with HSV-1 (strain McKrae) by the corneal route. The spread of HSV to the brain stem and the ventricular ependyma was investigated. The polymerase chain reaction (PCR) was used to detect HSV-DNA in the CSF during the course of infection. The ependyma of the third and fourth ventricle and the central canal contained viral antigen at a late stage of infection in up to 60% of mice. At this stage we found that many animals gave a positive PCR in the CSF although no antigen could be detected in the ependymal cells. The presence or absence of antigen containing cells could not be related to detection of HSV-DNA in the CSF. The results show that infection of the ventricular wall is not important for the spread of HSV to the CSF.
