Schistosoma spindale (Montgomery,1906) is a trematode inhabiting the portal and mesenteric veins of Bubalus bubalis. It was discovered by Montgomery(1906) from cattle in Mukteswar, India[1]. Indopanorbis exustus is the intermediate host of Schistosoma spindale. It is the site were the development of egg to the cercariae takes place. The cercaria is a feeble swimmer and in water its movements are mostly up and down. The cercariae can infect the host by oral route or by piercing the skin. It causes hepato-inestinal Schistosomiasis. The pathology caused by the parasite is due to injury caused by the migrating cercaria, injury by the adult parasite in the blood vessels and by the injury caused by ova. Animals with heavy infection suffer from anaemia, debility, emaciation and diarrhea, ending fatally. Two separate processes of invasion in the life history can be recognized. The first invasion involves the entry of the parasite into the host’s body, while the second invasion occurs when the parasite invades the particular tissue of the host where it lives. The adaptability of the S. spindale in the host is aided by its unique morphological and physiological characteristics. The present study had been carried out on the ultrastructure of S.spindale. The adults show sexual dimorphism. The male S. spindale is shorter, coiled and stouter. The female S.spindale is long and sender. The male bears the female in the ventral canal, the gynaecophoric canal. There is bisexual pairing of adult worms. They live in the bloodstream of warm-blooded hosts. A spindale shaped ova which is the characteristic of S. spindale is found.
