India has 1.77 million equines comprising 0.70 million horses and ponies, 0.29 million mules and 0.78 million donkeys. India has been richly and uniquely endowed with diverse bio-and-eco spheres that, in addition to supporting a huge and diverse live stock population, also contribute to the maintenance of variety of endemic bacterial, viral, fungal, parasitic and protozoan diseases. A horse suffers from variety of disease condition that is infectious diseases and non-infectious. Infectious diseases are caused by minute member of vegetable kingdom- bacteria, parasites, fungi and viruses. Amongst haemoprotozoan diseases, trypanosome can infect most mammals, although horses and camels are the principal hosts and represent the most significant source of economic loss. Trypanosomiasis, an arthropod borne blood protozoan disease commonly known as Surra is caused by Trypanosoma evansi. Several species of haematophagous flies, including Tabanids and Stomoxys are implicated in transferring infection from host to host, acting as mechanical vectors. The disease is characterized by fever, progressive emaciation, anaemia, subcutaneous oedema, nervous signs and death.enveterinary science, veterinary medicinestudyThesis
