What is Strongyloides westeri?
Strongyloides westeri is a threadworm parasite found in the small intestine mainly in foals at up to about 4 months of age. This parasite is associated with small intestinal enteritis and diarrhea as well as skin irritation and a clinical syndrome called “frenzied behavior” due to percutaneous invasion.
How do horses get strongyloides Westeri?
Strongyloides westeri is an intestinal parasite that can infect foals as early as four days after birth. A foal becomes infected by ingestion of larvae in the dam’s milk or by penetration of the foal’s skin by infected larvae in the bedding.
Is Strongyloides westeri zoonotic?
stercoralis is the only species considered zoonotic. Strongyloides papillosus in calves has been linked to heavy fatalities under conditions of high stocking density. Strongyloides westeri and Strongyloides ransomi of horses and pigs, respectively, cause only sporadic clinical disease.
What are the different methods of transmission which can occur with strongyloides Westeri in horses?
westeri through transmammary, percutaneous and oral routes. However, the transmammary route is considered the main source of transmission where L3s are transmitted from mare to foal via milk, which starts as early as day 4 postpartum and may continue up to several weeks [2,3,4].
What are strongyloides in horses?
Strongyloides westeri is an intestinal threadworm commonly infecting young foals, and it has been associated with small intestinal enteritis, resulting in diarrhea. The pathogenicity of the parasite remains unclear, however.
What is Cyathostomes?
Cyathostomes are a nematode more commonly known as small redworm. They are particularly dangerous to horses and the main cause of clinical disease in equines in the UK. The adult worm lays eggs in the gut. These eggs are passed in the dung and are visible under a microscope.
What disease does Strongyloides stercoralis cause?
Strongyloidiasis is an intestinal infection caused by a type of roundworm called Strongyloides stercoralis. It can live and reproduce in your intestines for decades without causing symptoms.
Is Strongyloides a hookworm?
Strongyloides stercoralis and hookworms are parasitic intestinal nematodes that belong to the group of soil-transmitted helminths (STH). For both parasites, infection occurs when larvae living in faecally-polluted soil penetrate intact skin.
How do you treat Strongylus vulgaris?
The diagnosis of S vulgaris-associated intestinal infarction is made by exploratory laparotomy, and the only curative treatment is resection of the infarcted tissue, where possible. Strongylus vulgaris belongs to the group of large strongyles (strongylidae) and is one of three Strongylus species infecting horses.
What is the common name of strongyloides Stercoralis?
threadworm, (Strongyloides stercoralis), worm of the phylum Nematoda that is parasitic in the human intestine but is able to live freely and breed in the soil. It is especially common in the moist tropics.
How do you get rid of a horse’s Strongyle?
To treat the small strongyles infection, your vet will also likely prescribe anthelmintics such as:
- Benzimidazoles – e.g. fenbendazole and oxfendazole.
- Macrocyclic lactones (ML) – e.g. ivermectin and moxidectin.
- Tetrahydrophyrimidines – e.g. pyrantel salts.
What kills large strongyles?
Oxfendazole
Oxfendazole, which kills large strongyles, roundworms and pinworms. Pyrimidines, also called pyrantel salts, have several applications. Resistance to chemicals in this class is growing among small strongyles.
How is Strongyloides westeri passed from Mare to foal?
The strongyloides westeri parasite can be present in the intestines of the mare at foaling and can be passed from the mare to the foal through the milk ingested from the mare after birth. The parasite can be successfully treated and, if found quickly enough, the foal need not suffer significantly permanent disability.
What kind of disease does Strongyloides westeri cause?

What are the symptoms of Strongyloides sp in horses?
Symptoms of Strongyloides sp in Horses. As noted above, this parasite can infect a newly born foal and can occur within 4 days of birth. These are the most noticeable symptoms that you will likely see in your infected foal: Diarrhea – Can be severe and won’t respond to normal treatments for diarrhea. Weakness. Weight loss.
What kind of life cycle does Strongyloides have?
In the environment, Strongyloides undergoes a complex life cycle with alternating free-living and parasitic generations. 2 Eggs hatch and larvae develop to become either free-living males and females or infective third-stage larvae. Sexual reproduction by free-living stages produces only larvae that are destined for a parasitic existence.
