2018 ACVIM Forum Research Abstract Program: Seattle, Washington, June 14 - 15, 2018

Healthy adult horses (n=14) and horses with a complaint of neurologic disease (n=7) were used. Cerebrospinal fluid was collected from both sites in randomized order. Continuous data were analyzed using mixed-effects linear models and count data using mixed-effects negative binomial regression. Statistical significance was set at P < 0.05. Medical records of adult horses and foals admitted to a Veterinary Teaching Hospital from 1979 through 2017 were examined for cases presenting with signs of diffuse brain disease, and serological or postmortem diagnosis of Eastern Equine Encephalitis. There were 104 cases that met the inclusion criteria. Data retrieved included season at admission, signalment, physical examination, neurologic evaluation, and clinicopathologic findings at presentation; as well as duration of hospitalization, treatment, and case outcome. Where available, historical information (i.e. vaccination status, treatment prior to referral) was also included.
