Debilitating disease in humans caused by parasitic worms (helminths) is estimated to be equivalent to the loss of at least fifty million productive years of life, whilst agricultural losses can be measured in hundreds of millions of dollars. As international efforts to sequence helminth genomes and transcriptomes gather pace, a systematic approach to the curation, integration and presentation of this data is needed to provide maximum utility for biomedical and agricultural research.WormBase
(http://www.wormbase.org) has approached this problem from two directions. Firstly, we have expanded our sequence curation activities to include selected parasitic nematodes with defined research communities, namely: Brugia malayi (causative agent of lymphatic filariasis), Onchocerca volvulus (river blindness), and Strongyloides ratti (rat model for strongyloidiasis). We now administer the reference genomes for these species, and actively curate the gene models and other annotations. Secondly, we have created a sub-portal, WormBase ParaSite
(http://parasite.wormbase.org), aimed at researchers engaged in parasitic worm genomics. WormBase ParaSite encompases flatworms as well as nematodes, and provides genome sequence, genome browsers, semi-automatic annotation and comparative genomics data for approximately one hundred species. Additional tools include a cross-species data-mining platform, protein and nucleotide sequence search, and a variant effect predictor to enable the analysis of different strain/isolate genomes in the context of the reference.
