Isolation of non-O1 Vibrio cholerae associated with enteric disease of herbivores in western Colorado

Le résumé fourni par la source

Non-O1 Vibrio cholerae was isolated from a horse (Equus caballus), a lamb (genus Ovis), and two American buffalo (Bison bison) suffering from enteric disease in the western part of Colorado. In 1981, a foal died of apparent respiratory failure. Necropsy findings included heart failure and gastroenteritis. V. cholerae serovar 347 (Smith) was isolated from the colon of this animal. V. cholerae serovar 27 (Smith) was isolated in 1983 from the intestine of a feedlot lamb suffering from pneumonia and severe watery diarrhea. In 1984, an enteric disease occurred in a herd of American bison. The sick animals were depressed and separated from the herd, dying in about 3 days. Of approximately 100 adult bison, 7 died. Necropsy of one animal revealed that gross lesions were limited to the gastrointestinal tract. V. cholerae serovar 27 (Smith) was isolated from the abomasum, duodenum, and colon of this animal. A swab specimen from the intestine of another dead bison also yielded V. cholerae serovar 27 (Smith).
