Lungworms
(Dictyocaulus
arnfieldi)
Lifecycle: Lungworm 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.
How
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 appetite.
Infection is usually light in older horses because they develop
resistance to the parasite and usually have no signs. If foals are
infected, they could die from a lungworm infection because they
have less immunity. That's why it's a good idea to separate older
horses from young foals and to maintain a regular deworming program.
