Abstract

Feces from 1,451 horses entering a veterinary hospital over a 13-month period were cultured for salmonella. A total of 46 horses (3.2%) yielded 1 or more salmonella-positive fecal cultures. Twenty horses were found to be excreting salmonella in the feces on admission, and 5 of these later had severe diarrhea associated with enteric salmonellosis. Abdominal surgery and other severe stresses were associated with all cases of severe enteric salmonellosis. Serotypes of salmonella isolated included Salmonella agona (15), S anatum (14), S. typhimurium (7), S. typhimurium var copenhagen (4), S. infantis (2), S. montevideo (1), S. meleagridis (1), S. drypool (1), and an unnamed Salmonella serotype (1). Seven deaths were attributed to 4 serotypes (S. typhimurium, 3; S. anatum, 2; S. typhimurium var copenhagen, 1; and S. montevideo, 1). A marked seasonable incidence in isolations was found, with isolations highest in later summer to early fall and lowest in the spring. It was also found that horses can shed salmonella intermittently, and a minimal of 5 consecutive negative fecal cultures is recommended before considering a horse not to be infected with salmonella.
