About Schistosoma mansoni

The trematode Schistosoma mansoni is one of the three major infectious agents responsible for the chronic debilitating disease schistosomiasis found throughout Africa and South America. The intermediate host for the parasite is a freshwater snail from the genus Biomphlaria, and the definitive host is a human. Schistosomiasis is widely considered to be second only to malaria as a global health problem and an incalculable drain on the economic development of endemic countries.

Genome Assembly & Annotation


Unpublished data

This is an unpublished genome project (publication pending). Before working with these data, please read our Policy for using unpublished data.

The reads from short and long-range paired end capillary libraries and short-range Illumina paired end libraries were mapped to assembly accession GCA_000237925.2 (Protasio et al 2012; version 5.2). Mapped reads were scrutinised in GAP5 and manual edits to the assembly were made as necessary. After inspection of optical map alignments and integration of PacBio reads, version 7 was produced (GCA_000237925.3; unpublished). More information can be found in this pre-print by Buddenborg et al 2021. Following incorporation of HiC data, and further PacBio analysis to resolve repeats a near-complete chromosomal assembly v10 is now available (unpublished) and presented here.


Putative gene models from the annotation accompanying previous assembly GCA_000237925.3 and predictions using RNASeq data were resolved through manual curation using WebApollo as a platform. For unchanged gene models, previous gene identifiers have been preserved.
