Abstract
Clinical, bacteriological, serological and hematological observations were made on 13 adult ponies orally inoculated with Salmonella typhimurium. The results were compared to 2 control ponies and 4 others infected by accidental transmission. The clinical responses in inoculated ponies included pyrexia lasting 4 days and neutropenia during the first 5 days after inoculation followed by a neutrophilia. Pyrexia and neutropenia were associated with maximal shedding of organisms in the rectal feces. Changes in the character of the feces occurred between 1 and 2 days after inoculation and appeared associated with the serological response. Serological responses occurred in all infected ponies except one. At necropsy, of the 14 ponies with positive cultures in the colon, 7 had negative cultures in the rectal feces. Serological studies performed on 43 clinically normal horses indicated a correlation between age and Salmonella agglutination titer.
