Abstract: | Medical records from 394 dogs and cats that had endoscopic aspiration of intestinal contents for identification of Giardia sp. trophozoites were retrospectively reviewed. The most common indications for endoscopy were chronic vomiting (152), chronic diarrhea (108), chronic vomiting and diarrhea (58), and acute vomiting (33). Metronidazole had been previously administered to 111 animals (28.2%), and to 58.6% of those with chronic diarrhea. Six aspirate samples (1.5%) were positive for Giardia sp. In 3 of these cases a single fecal flotation identified Giardia cysts before endoscopy. The authors conclude that intestinal aspiration in animals from a primarily referral population undergoing upper gastrointestinal endoscopy rarely identifies Giardia and should not be routinely performed. However, animals in which zinc sulfate flotation was not performed or those that did not previously receive metronidazole might benefit from intestinal aspiration. |
