title: Duodenal aspiration via flexible endoscope for diagnosis of giardiasis in a dog.
abstract: A 1-year-old male Pointer was admitted for evaluation of chronic diarrhea and mild weight loss. An aspirate of duodenal contents was obtained after infusing 0.9% Na Cl through a flexible endoscope passed into the proximal portion of the duodenum. Examination of the aspirated duodenal contents revealed a Giardia trophozoite, and the dog improved with metronidazole therapy. Duodenal aspiration via a flexible endoscope offers a new diagnostic technique for giardiasis.
