The blood fluke Schistosoma mansoni is an important human parasite. It causes the debilitating disease intestinal schistosomiasis, a major global health problem affecting around 83 million people in 56 countries (mainly in Africa and South America). While humans are the primary host, the S. mansoni life cycle also involves transmission to and from an intermediate freshwater snail host, and thus schistosomiasis (bilharzia) is closely linked with poverty and poor sanitation.

The S. mansoni genome, derived from cercaria (larvae) of a Puerto Rican isolate, was first released in 2009. It is 363 Mb in size and contains around 12,000 protein-coding genes.
