Parasitic Castration in Freshwater Snail Melanoides tuberculatus (Mollusca: Gastropoda)

Abstract Structure of ovotestis and its parasitic castration were observed histologically in hermaphrodite freshwater snail Melanoides tuberculatus (Mollusca, Gastropoda). In mature healthy snail ovotestis was found to be closely associated with posterior region of digestive gland. It was composed of numerous oval to pear-shaped acini intermingled with loose inter-acinar connective tissue. Each acinus was found to be made up of two unequal zones, the larger testicular zone comprising of male germ cells and the smaller one with the female germ cells. Both of them were lined by germinal epithelium. Oocytes were generally found towards the periphery of ovotestis enclosed by the membrane tunica propria. In infected snails ovotestis was found to be invaded by the larval trematode parasites (sporocysts and xiphidiocercariae) but the larvae were restricted to the connective tissue of ovotestis and did not invade the acini. Except ovotestis no other organ was found to be infected with these larvae. Histopathological changes in the acini of infected ovotestis were associated with the severity of infection. Degenerative changes, hypotrophy and destruction of individual acinus were found in mild infection. In severe infection, autolysis and necrosis of acinar cells were found and ultimately these were completely replaced by parthenitae. In such parasitic castration no sex conversion was detected. In the present communication structure of ovotestis along with parasitic castration and its evolutionary significance are discussed.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
