Abstract: Chelonians are common reptiles that are being domesticated. Endoparasitic infestation is one of the major concern of health issues that may cause signs of anorexia, regurgitation and obstruction. A 7 year old male turtle was presented to the VCC, CVSc., Rajendranagar with a history of abnormal faecal excreta and presence of cream coloured thready structures in the tank where the turtle was placed. Detailed history revealed that he was showing disinterest towards food but with normal vital parameters. Microscopic examination of the fecal sample revealed the presence of elliptical shaped ova with actively moving larva. The sample also revealed the presence of active larvae with a cylindrical elongated body, with a pointed head, thus confirming the pinworm infestation. The turtle was treated with a single dose of fenbendazole at 50 mg/kg, along with multivitamin drops. However, the regimen was repeated after two weeks. Following therapy, the turtle regained its normal activity along with interest towards food.
