The lungworm Heterostrongylus heterostrongylus (Nematoda: Metastrongyloidea
) is reported for the first time from the Virginia opossum Didelphis virgin
iana in North America. Seventeen of 31 opossums (55%) examined from San Die
go County, California, U.S.A., were infected with H. heterostrongylus, with
intensities ranging from 8 to 128 worms per host (mean 41). Another specie
s of metastrongyloid nematode, Didelphostrongylus hayesi, was found in 74%
of the lungs examined, with intensity ranging from 2 to 1,328 worms per hos
t (mean 312).
