Abstract
In the present study, post-mortem was conducted on a female elephant aged about 37 years died at Rajeev Gandhi National Park, Hunsur, Mathigoodu Elephant Camp, Karnataka state. The animal suffered with diarrhoea, anorexia, dehydration and was unable to walk for about one week before death and was treated with antibiotics and fluid therapy for three days. The post-mortem examination revealed that, the gastric mucosa was severely congested, hyperaemic and numerous stomach bots attached to the mucosa. The bots were recovered from the gastric mucosa and processed for species identification. The posterior spiracles of the bots showed three longitudinal parallel slits in each spiracle, the abdominal segments had a row of belt like triangular shaped spines and the anterior end had two powerful oral hooks with cephalo-pharyngeal skeleton. Based on the above said morphological characters, the bots were identified as Cobboldia elephantis. This seems to be the first report of C. elephantis in free range wild elephant from Karnataka state.
