title: Observations on the distribution of canine distemper virus in the central nervous system of dogs with demyelinating encephalitis.
abstract: The distribution of canine distemper virus in the central nervous system was examined in 11 dogs with demyelinating encephalitis by the direct fluorescent antibody technique on paraffin sections of brain and spinal cord. In the grey matter there was a good correlation between the presence and severity of lesions and presence and amount of viral antigen. Large concentrations of virus were found in neurons and their processes. In most demyelinating lesions only small amounts of viral antigen were found, mostly located in astrocytes. The potential importance of the role of the astrocyte in demyelination in canine distemper virus infection is stressed.
