Abstract
The viral etiology of the epizootic was ascertained through the isolation of a type A influenza virus and by evaluation of the immunological response of the sick horses, as demonstrated by complement fixation and hemagglutination-inhibition tests. The agent proved to be similar to a type A2 virus isolated from humans this year. Because of the widespread nature of this epizootic, one cannot exclude the possibility that was an expression of an attack by the virus on an unprotected population of horses without previous infectious experience with the influenza virus.
