Family: Protostrongylidae
Genus: Parelaphostrongylus
Boev & Schultz, 1950[1]

Parelaphostrongylus is a genus of parasitic nematodes belonging to the family Protostrongylidae. All species in this genus use North American cervids as definitive hosts.[2]

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]
