Meningeal Worm

The larvae of this parasite is passed in the feces of the white tailed deer. The larvae then enter ground snails which can be ingested by llamas and alpacas in the pasture. The larvae then migrate throughout the spinal cord and the brain causing damage to the central nervous system. There is no way to diagnose Meningeal Worm definitely, but sometimes symptoms can be treated effectively. Most common symptoms are rear leg weakness, lameness, staggering and stiffness, circling, abnormal head position, and gradual weight loss. Treatments include multiple doses of a de-wormer and an anti-inflammatory. A preventative treatment in areas populated with white tail deer is monthly dewormings with injectible Ivomectin.
