About Gongylonema pulchrum

The nematode Gongylonema pulchrum is an accidental parasite of humans causing gongylonemiasis. Only around 100 cases in humans have been reported. Transmission to humans is due to consumption of food and water contaminated by coprophagous insects, mostly dung beetles and cockroaches. A large worm that burrows in the mucosal lining of the esophagus and mouth including the tongue, soft palate and lips

Genome Assembly & Annotation


The draft genome assembly was produced by the Parasite Genomic group at the Wellcome Trust Sanger Institute, in collaboration with Hiroshi Sato (Yamaguchi University) as part of the 50 Helminth Genomes project. The assembly uses 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.
