About Diphyllobothrium latum

The cestode Diphyllobothrium latum, or broad fish tapeworm, is a parasite of fish and mammals. The parasite causes diphyllobothriasis in humans through consumption of raw or undercooked fish. Symptoms of diphyllobothriasis are generally mild, and can include diarrhoea, abdominal pain, vomiting, weight loss, fatigue, constipation and discomfort.

Genome Assembly & Annotation


The draft genome assembly was produced by the Parasite Genomic group at the Wellcome Trust Sanger Institute, in collaboration with Tomáš Scholz (Academy of Sciences of the Czech Republic), using Illumina paired-end sequencing followed by an in-house genome assembly pipeline comprising various steps, including contig assembly, scaffolding, gap-filling and error-correction (Helminth Genomes Consortium, unpublished).


The gene predictions were made by the Parasite Genomics group at the Wellcome Trust Sanger Institute and WormBase, as part of the 50 Helminth Genomes Initiative (Helminth Genomes Consortium, unpublished). An in-house pipeline was developed that used MAKER to generate high-quality annotations by integrating evidence from multiple sources: ab initio gene predictions from AUGUSTUS, GeneMark-ES, and SNAP; projected annotation from C. elegans (using GenBlastG) and the taxonomically nearest reference helminth genome (using RATT); and ESTs, mRNAs and proteins from related organisms aligned to the genome using BLAST, with refinement of alignments using Exonerate.
