Nematomorpha (sometimes called Gordiacea, and commonly known as horsehair worms, hairsnakes, [1] [2] [3] or Gordian worms) are a phylum of parasitoid animals superficially similar to nematode worms in morphology, hence the name. Most species range in size from 50 to 100 millimetres (2.0 to 3.9 in), reaching 2 metres (79 in) in extreme cases ...
Mature horses appear to develop a certain degree of resistance to this parasite, but it is a concern for younger horses up to about two years old. [4] P. equorum is one of the few parasites where a natural immunity develops in the host. [3] However, when an infection is found in an adult horse, both the worm and egg counts are substantially low ...

Strongylus vulgaris (large strongyles), [1] commonly known as the blood worm, [2] is a common horse parasite in the phylum Nematoda. It looks like a long worm with a large biting mouth. They are usually reddish in color because of all the blood they take from the equine host. [1]
Skin lesions probably due to Habronema Horse recovering from skin lesions probably due to Habronema, after treatment with ivermectin. For most horses, the lesions will resolve by the end of summer. Topical or systemic treatment with Ivermectin is effective against Habronemiasis. Ivermectin or moxidectin can eliminate nematodes in the stomach.
Once ingested by the insect the worm larva penetrates the gut wall and develops in a cyst in the tissue outside. [4] It emerges as an adult worm in a few months. [3] Gordius worms have been recovered from human vomit, [7] feces, [8] and urine. When worms are expelled from the gastrointestinal tract, their mode of entry was likely ingestion of ...
