larvae go through intestinal walls into the circulatory system where
they are carried to the lungs and mature. Eggs pass through the horse's
system in manure.
It Gets Into Your Horse: Lungworm larvae are swallowed as your horse
eats infected grass.
Dangers If Left Untreated: Lungworm larvae irritate
the small air sacs in the lungs, called the bronchioles,
which can cause the horse to have a severe cough, difficulty
breathing and loss of aphorseite.
Older horses usually develop a resistance
to lungworms, but foals can die from an infection because they have less immunity to the parasites.
