Abstract
| - Abstract. The maintenance and infection of Oncomelania hupensis hupensis, the intermediate host of the Chinese strain of Schistosoma japonicum, is described. 60% of the snails exposed to miracidia became patent, and 5000 patent snails can be produced which yield over 250 000 cercariae per week. The maintenance and infection of snails require less than 8 man-hours per week.
