Studies on Schistosoma incognitum Chandler, 1926

Abstract
While human schistosomiasis is hardly a problem in India, schistosomiasis in domestic animals is a problem of considerable importance. Blood-flukes infect almost all the species of Indian domestic animals, and often seriously undermine their health and usefulness. Seven species of schistosomes are known to occur in Indian mammals, viz. Schistosoma indicum Montgomery (1906a), S. spindalis Montgomery (1906b), S. incognitum Chandler (1926), S. nasalis Rao (1933), Bivitellobilharzia nairi (Mudaliar & Ramanujachari, 1945) Dutt & Srivastava (1955), Orientobilharzia dattai (Dutt & Srivastava, 1952) Dutt & Srivastava (1955), and Orientobilharzia bomfordi (Montgomery, 1906b) Dutt & Srivastava (1955). The reported occurrence of Schistosoma bovis (Sonsino, 1876) Blanchard (1895) in India needs confirmation.
