abstract
Tigers are unlisted as endangered species in the redlist of IUCN. India is currently hosting highest numbers of tigers from all over the world. The role of tigers in balancing the ecosystem is very critical. So, it is a call of time to take special care for upholding the population of this species for maintaining a healthy environment. In this case report we have discussed about a tigress infected by Trypanosoma evensi captive in Assam state zoo cum botanical garden. The animal, was showing signs of pyrexia, inappetence and depression. The diagnosis was confirmed by microscopic examination of wet blood smears, Giemsa-stained blood smears and positive Formol Gel Slide Test (FGST). Earlier there was no report available for Trypanosoma infection from the concerned population of the zoo. This case report may put some light towards Trypanosomiasis in wildlife.
