Genomes for the entomopathogenic nematode Steinernema carpocapsae and four congeners–S. scapterisci, S. monticolum, S. feltiae, and S. glaseri are now available in WormBase Parasite. Check out the paper describing these genomes.
In the previous WS246 release we introduced automated gene descriptions for C. elegans genes that lacked a manually written one. These gene descriptions include information related to orthology, process, function and sub-cellular localization (when these data-types have been curated in the WormBase database), giving the user a quick overview of the gene. The current WS247 release includes automated descriptions for over 18,000 C. briggsae genes. Check out the C. briggase gene pages to view these descriptions under ‘Overview’! In future releases, we will add genes from many more species! Also, WormBase is working on user-friendly forms which you can use to edit these descriptions and make them better.
* Data from Inparanoid was updated to version 8
* Orthology data for all core nemtatodes and model organisms was imported from WormBase Parasite release 1
* OMA and TreeFam data was removed in preparation for an update (TreeFam accessions will remain as database crossreferences)
Expression and Picture update
* A large set of expression graphs for other nematodes produced by Yanai’s has been added
The RNASeq data will become richer in WS247.
There will also be “control” mean and median FPKM values derived from the data which does not have a specific experimental condition applied.
New/updated reference genomes
This release we see a rebuild of C. elegans, B. malayi and O. volvulus. Various data classes and curational activites have been undertaken on these species since the release of WS246
Parasitic worms (helminths) are responsible for more than a billion human infections globally and have a devastating impact on livestock and agriculture. As international efforts to sequence the genomes of parasitic helminths gather pace, the WormBase groups at EMBL-EBI and Wellcome Trust Sanger Institute have collaborated on the creation of a new BBSRC-funded resource, WormBase ParaSite, to analyse, store and present information on these genomes. WormBase ParaSite is closely integrated with and complementary to the main WormBase web-site, the central mission of which is to support researchers using Caenorhabditis elegans as a model system.
The first release of WormBase ParaSite includes annotated genomes from 82 species (57 nematodes and 25 platyhelminths), with features including:
- A genome browser for every genome
- Comparative analysis (gene orthology and paralogy) using the Ensembl Compara Gene Tree inference method
- Full text and sequence search (BLAST) services
Development in the coming months will see improved cross-linking to and from the main WormBase site, incorporation of new genomes and data sets, and new querying interfaces and tools oriented towards the use-cases of parasitologists.
A new genome of a zoonotic whip worm species, Trichuris suis, has been made publicly available by the Gasser lab of Melbourne University.
As part of the research into the unique properties of the genome, a male and a female worm has been sequenced, assembled and annotated as described in Genome and transcriptome of the porcine whipworm Trichuris suis.

Nat Genet. 2014 Jul;46(7):701-6. doi: 10.1038/ng.3012. Epub 2014 Jun 15.
It has been included as part of the WS243 release of WormBase and is shown on a Genome Browser, as well as on orthology sections of genes. Flatfiles of the raw data are also available on ftp://ftp.wormbase.org.
