Encyclopedia
Hassalstrongylus forresteri is a nematode
worm of the genus Hassalstrongylus
that infects the marsh rice rat
(Oryzomys palustris) in the United States. It was first described as Hassalstrongylus musculi
by Marie-Claude Durette-Desset in 1972, but she later recognized it as a different species, H. forresteri. The females cannot be distinguished from those of the other species in the marsh rice rat, H. musculi and H. lichtenfelsi
