==Description==

Equine grass sickness causes a paralysis of the gastro-intestinal tract, by disruption of the autonomic nervous system. The condition may occur acutely, or progress chronically over several weeks, but is fatal in all cases. The aeitology is unknown but an ingested neurotoxin appears to be involved. The neurotoxic is absorbed from the intestinal tract and selectively binds to the autonomic nerve terminals resulting in degeneration and loss of neurons.
