Parelaphostrongylus (redirected from Parelaphostrongylus andersoni)

Parelaphostrongylus

a genus in the worm family Protostrongylidae.

---

Parelaphostrongylus andersoni

found in the musculature, especially in the longissimus dorsi, in white-tailed deer.

Parelaphostrongylus odocoilei

found in connective tissue around blood vessels and lymphatics of musculature below the vertebral column, abdomen and proximal parts of the limbs in mule and black-tailed deer and in moose.

Parelaphostrongylus tenuis (syn. Pneumostrongylus tenuis, Odocoileostrongylus tenuis, Elaphostrongylus tenuis, Neurofilaria cornelliensis)

found in the cranial venous sinuses of white-tailed deer but is nonpathogenic in this species. Infection also occurs in moose, elk, caribou, red deer, black-tailed deer, llama, sheep and goat. In these species the migrating larvae cause serious damage in the spinal cord and posterior paralysis, often in a number of animals at the one time. Called also moose sickness.

Some infected goats also develop a local, linear dermatosis over the shoulders, thorax and flanks, believed to be caused by migrating P. tenuis larvae irritating nerve roots which leads to pruritus and self-trauma along dermatomes.
