About Angiostrongylus costaricensis
The nematode Angiostrongylus costaricensis is the causal agent of abdominal, or intestinal, angiostrongyliasis. Humans are incidental hosts that become infected through ingestion of raw or undercooked infected rats (definitive host) snails, slugs, crabs, freshwater shrimps, or vegetables contaminated by slime from or parts of infected snails and slugs.
Genome Assembly & Annotation
The draft genome assembly was produced by the Parasite Genomic group at the Wellcome Trust Sanger Institute, in collaboration with Antonio Osuna (Universidad de Granada) 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.
