About Schistosoma japonicum
The trematode Schistosoma japonicum, or Asian blood fluke, is a parasite of significant public health importance in China, Taiwan, the Philippines and Southeast Asia. S. japonicum is one of the three major infectious agents responsible for the chronic debilitating disease schistosomiasis. The intermediate host for the parasite is snail and the definitive host a wide range of at least 31 species of wild mammals, therefore it can be considered a true zoonosis. Burdens of morbidity are high and schistosomiasis may contribute to several hundred thousand human deaths annually.

Genome Assembly & Annotation
Assembly
The full assembly process is described in Xu et al., (2022). Scaffolding was conducted using bowtie 2 version 2.3.3.1. Raw PacBio reads were aligned to each other using daligner, executed using the falcon (version 0.7) assembler. Overlapping reads and raw subreads were processed to produce consensus sequences.
Annotation
The full annotation process is described in Xu et al., (2022).
