Hassalstrongylus is a genus of nematode worms that infect mostly muroid rodents from eastern North America to South America. The genus is part of the Heligmonellidae and related to genera like Stilestrongylus.^[2]

Notes

1. Durette-Desset transferred Longistriata musculi Dikmans, 1935, to Hassalstrongylus in 1972, but in 1974 recognized that she had based her earlier opinion on material that was not referable to H. musculi, but to a new species which she named H. forresteri.^[11]
