Abstract
The present study reports pathological conditions associated with Physaloptera sp. stomach worm infestation in Bengal monitor lizard (Varanus bengalensis). Four adult Bengal monitor lizards were rescued from the poachers and kept at Wild Animal Rescue and Rehabilitation Centre, Bannerghatta Biological Park, Bengaluru. Faecal samples from all were collected and examined. Physaloptera sp. ova were found in all faecal samples examined by sedimentation technique. One Bengal monitor lizard died during the period and systematically examined at necropsy for gross pathological lesions. Adult Physaloptera sp. nematodes were found to be firmly attached to the gastric mucosa causing erosive inflammatory foci. Histopathological examination of stomach revealed the presence of many immature and mature worms encapsulated within fibrous connective tissue. The intestinal villi were stunted and many cross sections of the worms could be demonstrated in the lumen. The worms also migrated to liver parenchyma and got encapsulated with fibrous connective tissue with infiltration of eosinophils in the sinusoids and the vascular tissue spaces. This seems to be the first report of Physaloptera sp. nematodiasis in Bengal monitor lizard kept under captivity for a period of 1.5 months.
