General information about the disease:
Cyathostomin (small strongyle) larvae migrate deep into the mucosa or submucosa of the equine large bowel (mainly cecum and ventral colon) to molt and develop. Third or fourth stage larvae may undergo hypobiosis persisting in nodules in the bowel wall. Emergence of the larvae (sporadically or synchronously) causes significant mucosal damage and eosinophilia, resulting in diarrhoea and protein-loss. Horses >1-year-old are affected, typically in late winter, spring, and summer when larvae emerge.
General information about when this test is indicated:
