Species
Three species are assigned to this genus:[1]
- Parelaphostrongylus andersoni Prestwood, 1972
- Parelaphostrongylus odocoilei (Hobmaier and Hobmaier, 1934)
- Parelaphostrongylus tenuis (Dougherty, 1945)
Life cycle
Infected cervids pass first-stage larvae in their fecal pellets. After coming into contact with the larvae, gastropods become intermediate hosts and facilitate development of the larvae to the infective third stage.[3] Transmission to the definitive hosts occurs when cervids inadvertently consume infected gastropods along with food.[3] Infective larvae of Parelaphostrongylus odocoilei have been shown to emerge from gastropod hosts in lab conditions, raising the possibility of an alternate transmission route.[4]
