Lungworms
Are a parasite that require careful treatment and quick intervention if they infect your horse or foal.

Other Names
Dictyocaulus arnfieldi

Description
Adult Lungworms are long and thin and can range from 25 to 70mm in length

Lungworm Infection

Lungworm eggs are passed out in the droppings of infected horses.
The eggs travel to the intestines and it is from here that they burrow through the walls of the intestines and enter the circulatory system.
Via the circulatory system they enter the lungs and it is here that the most damage is caused.
The larvae irritate the bronchioles in the horses lungs and often cause a persistent cough and difficulty in breathing as well as a reduced appetite and sense of well being.
The larvae mature into adults in the lungs and the female lungworm lay eggs.
These eggs are coughed up and re swallowed and leave the horse in the droppings.

Horses At Risk
All horses are potentially at risk, more mature horses develop a resistance to Lungworms, but foals do not posses this immunity and are therefore at risk

Symptoms

Persistent cough
Parasitic bronchitis
Difficulty in breathing
Loss of appetite

Prevention

Where possible separate older horses from young foals
Maintain a regular de worming program.
Consult with your veterinary surgeon to ensure that you have an adequate worming programme in place.
Maintain good pasture management.
