ABSTRACT
Moaddab H, Haghighi Z M, Davoodabadi F.,
Survey (pathology) of enterocolitis in horses with salmonella, Onl J Vet Res., 20(5):312-318, 2016. Horses
(37) with diarrhea and abdominal pain were monitored over a 4 year period.
Twenty horses died and 17 survived. Two animals were positive for salmonella in
microbial culture from nasogastric reflux, 12 in feces and 20 in intestinal
content specimens at necropsy. Before treatment or death, 37 horses had
depression, tachycardia and tachypnea, 35 congested mucous membranes, 32 increased
CRT, 10 fever, 19 hypothermia, 26 diarrhea, 4 bloody diarrhea, 34 abdominal
pain, 15 nasogastric reflux, 21 ileus, 29 reduced abdominal sounds, and 25 gas
distended intestines upon rectal examination. At necropsy, 20 had severe
dilatation of stomach, 15 gas distention of cecum and colons,
19 petechial and echymotic hemorrages
in serosa and mucosa of small intestine and colons, 20 pale and enlarged
kidneys and 20 hemorrhagic adrenals. Microscopy revealed severe lesions in
cecum and colon with hemorrhage, superficial coagulative necrosis and mixed
inflammatory cell infiltrate.
