Intestinal intussusception secondary to enteritis caused by Pythium insidiosum in a bitch: case report

ABSTRACT We report a case of intestinal intussusception secondary to enteritis caused by Pythium insidiosum infection in a 1-year-old mixed breed bitch that died after a 30-day history of bloody diarrhea, anorexia, weight loss, listlessness, dehydration, and pale mucous membranes. Necropsy revealed two areas of intussusception, one jejunum-jejunal and one ileum-cecum-colic. The first intussusception showed slight congestion of the intestinal loop, which was resolved by manual traction, while the second intussusception exhibited thickening, irregular yellow spots, and transmural congestion. Histologically, the jejunum-jejunal segment had ischemic lesions secondary and ileum-cecum-colic intussusception there was also necrotizing, pyogranulomatous enteritis associated with negative images of intralesional fungal hyphae that were well visualized by silver impregnation. Immunohistochemistry identified the hyphae as Pythium insidiosum. The diagnosis was made based on the histological changes and confirmed by immunohistochemistry. We can conclude that enteritis by P. insidiosum in dogs can occasionally cause intestinal intussusception and result in acute death.
