About Hymenolepis nana

The cestode Hymenolepis nana, or dwarf tapeworm (previously known as Vampirolepis nana, Hymenolepis fraterna, and Taenia nana) is a cosmopolitan species most common in temperate zones. It is most often seen in children in countries in which sanitation and hygiene are inadequate and causes hymenolepiasis which rarely has symptoms.

Genome Assembly & Annotation


The genome was produced by the Parasite Genomic group at the Wellcome Trust Sanger Institute, 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.


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 project. 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.
