Common Equine Parasites

Large Redworms (Strongyles):
These Internal parasites are rather dangerous. The danger is they eat through the lining of the gut and migrate via blood vessels to cause severe bleeding and damage. Worst cases can be fatal.

Small Redworms (Cyathostomes/Small Strongyles):
The most common internal parasite to inflict horses. The larvae remain in the wall of the gut until after winter and appear in their droves in spring. As they appear en masse, purging all these worms causes impaction colic or death.

Roundworms (Ascarids)
Foals are at danger of adult roundworms that grow up to 50cm (19”) in length. Liver & lungs are infected, as the larvae are coughed up and swallowed, on maturing the egg laying adults lie in the digestive tract. If you notice nasal discharge or coughing treat accordingly.

Pinworms (Oxyuris)

Ever noticed your horse itching their backside? Pinworms are the likely culprit. These worms enter via the horses backside causing damage to the bowel. Constant irritation, scratching will cause open wounds and infection.

Threadworms (Onchocerca cervicalis)

The “silent” worm. Often dormant in the adult horse, and infect a foal through the mare’s milk. The health of the foal is affected from birth; common is stunted growth. Anaemia and dehydration through diarrhea. Deworming the mare during pregnancy will help the unborn foal start in life.

Tapeworms (Cestodes)

The “wide” worm, growth up to 1.5cm (0.06). Tapeworm causes a major problem as they are difficult to diagnosis via a Fecal Egg Count(FEC). Cause digestive problems and fatal blockages and colic. Enter through eating forage mites found on grass, straw/hay. If you hay is itching you, then you have mites.

Lungworms (Dictyocaulus arnfieldi)

Donkeys are carries (hosts) of lungworm. Solution to lungworms “Don’t share pasture with donkeys”. Side effects are constant coughing.

Bots (Gastrophilus)

Bot flies- a nuisance to horses and man. Appear in summer and lay eggs on the horse. Horse ingests the sticking eggs when licking or grooming itself and causes irritation in the horses mouth
and throat
