Abstract: | Enteric pythiosis was diagnosed in a 2-year-old Quarter Horse gelding. The horse had signs of colic, which appeared to be alleviated by administration of mineral oil and analgesics, but only temporarily. Intestinal distention developed after initial examination. At surgery, a thick stenotic area was observed in the middle portion of the jejunum. The thick intestine and associated mesentery contained multiple firm nodules of gritty caseous material. Histopathologic findings included sclerosing eosinophilic granulomatous enteritis and peritonitis. Although the lesion resembled a response to migrating parasites and lacked hyphae in initial sections, the gross appearance of the lesion prompted the acquisition of additional sections to detect the etiologic agent. |
