About Trichinella spiralis

Trichinella spiralis is a nematode parasite, occurring in rats, pigs, bears and humans, and is responsible for the disease trichinosis. It is sometimes referred to as the
"pork worm
" due to it being found commonly in undercooked pork products.


The genome was sequenced by the Genome Institute at Washington University in St. Louis, with support from the≈ of the National Institutes of Health (NHGRI - NIH).


The sequence, annotated with protein-coding gene predictions provided by the authors, was submitted to the INSDC in early 2011. Details of the annotation strategy can be found in Mitreva et al, 2011.
