Topic:Encephalomyelitis
Encephalomyelitis in horses refers to inflammation of the brain and spinal cord, often caused by viral infections such as Eastern, Western, and Venezuelan equine encephalomyelitis viruses. These conditions can lead to neurological symptoms including fever, ataxia, and behavioral changes. The disease can be transmitted through mosquito vectors, with horses serving as dead-end hosts. Diagnosis typically involves serological testing and clinical evaluation. This page aggregates peer-reviewed research studies and scholarly articles that explore the etiology, pathogenesis, clinical presentation, and management strategies for encephalomyelitis in equine populations.
The 1952 outbreak of encephalitis in California; epidemiologic aspects. For the most part, epidemiologic phenomena observed in the outbreak of encephalitis in 1952 accorded with patterns that had been apparent in previous years. Ninety-seven per cent of the 414 laboratory-confirmed cases of western equine and St. Louis encephalitis in humans occurred in the 20 Central Valley counties. The cases of western equine encephalomyelitis in horses were generally scattered over the state. In the Central Valley most of the cases in horses were in animals less than two years of age; elsewhere the incidence was higher in older horses.There were no laboratory-confirmed cases o...
California encephalitis virus, a newly described agent. In three cases of encephalitis in humans that occurred in the area where the newly described California virus was isolated from mosquitoes, serological evidence seemed to indict the California virus as the etiological agent. In the case of an infant with very severe disease, the serological evidence was convincing; the evidence was almost as strong in the case of a seven-year-old boy; the results in an adult were equivocal. Inapparent infection in man is quite common as indicated by neutralization tests on the sera of nearly 600 residents of California, but encephalitic manifestations of infec...
