Near-Eastern Equine Encephalomyelitis


DURING intermittent investigations of encephalitis of horses and donkeys in Egypt and Syria, spread over the past six years, we have isolated from infected equines and other hosts twenty-three strains of virus which, in respect of pathogenicity for laboratory animals and other characters so far determined, are indistinguishable. The equine disease, which is apparently carried by arthropods, conforms broadly to earlier descriptions of equine encephalomyelitis in the Middle East1–3; and, recently, we have recognized three outbreaks of encephalitis in sheep and one in cattle from each of which strains of virus, indistinguishable at this stage from the equine strains, have been isolated.
