2015 ACVIM Forum Research Abstract Program

Vaccination with a multivalent vaccine containing WN and EEE elicited an antibody response in horses and pony foals. However, vaccination for WN and EEE did not increase IgM titers >1:400, 7 days after vaccination in adult horses and ponies and after initial and 2nd vaccination in na€ ıve pony foals. Therefore, vaccination does not interfere with serologic testing for naturally occurring WN and EEE infections. Salmonella enterica is an important factor in healthcare-associated epidemics and zoonotic disease in veterinary hospitalswith outbreaks of multi-drug resistant (MDR) Salmonella among equine patients resulting in high case fatality rates and substantial financial cost. The objectives of this study were, 1) to determine factors associated with fecal shedding of MDR-Salmonella; and 2) to determine what effect Salmonella shedding may have on health outcomes of previously hospitalized horses and their stablemates.
