INFECTIOUS MONONUCLEOSIS AND ENCEPHALOMYELITIS

Abstract
Recent exptl. evidence supporting the theory that infectious mononucleosis is caused by a filterable virus is presented. Some viruses have affinities for the C. N. S. and a number of diseases such as poliomyelitis, rabies and encephalitis are the result of the neurotropic properties of these viruses. Many virus diseases such as measles and variola which usually do not show any affection of the C. N. S., in a few rare cases are complicated by encephalitis and myelitis. In the authors'' case which was characterized not only by a blood picture of infectious mononucleosis but also by a neurological picture of encephalomyelitis, it seemed quite reasonable to assume that the condition was caused by one virus with neurotropic properties rather than by 2 different viruses.
