Chorioptic Mange in Horses

Description

• Chorioptic mange is caused by small parasites called lice and is generally isolated to the lower legs of the horse. However, it can also be found on your horse's body and the base of the tail. According to Equine Science Update, chorioptic mange is more common in larger breeds of horses, such as draft horses, but it can affect other breeds as well.

Symptoms

• Not every horse infected with chorioptic mange will have the exact symptoms or have the same degree of symptoms. However, typically the area that is infected becomes itchy to the horse. The skin generally becomes inflamed as well. Alopecia, or hair loss, is common. As the skin becomes further infected by the mites that cause the mange, infections can occur, and open sores can develop. Because of the discomfort caused by the infestation, your horse may be seen stomping his feet or kicking. According to Equine Science Update, this behavior is more common at night.

Diagnosis

• If you suspect your horse has any of the signs and symptoms of mange, it is important to have a veterinarian examine your horse. Since the signs and symptoms of chorioptic mange can look similar to other diseases, a veterinarian will need to diagnosis your horse prior to treatment. Usually, your vet will take a scraping of the horse's skin and examine it under a microscope, according to Your Veterinary Clinic.

Treatment

• According to Merck Veterinary Manual, if chorioptic mange is left untreated, the problem will remain chronic; however, with treatment the mange will generally resolve. Before and after diagnosis is made, the hair around the affected site should be kept short. This will keep bacteria out of any open sores. After diagnosis, your vet may recommend a topical parasite treatment spray. This will help kill the mites on your horse's skin. The vet might also recommend giving your horse a Lyme sulphur dip or applying an antibiotic cream containing ivermectin. If your horse is battling a secondary bacterial infection because of the open sores, your vet may also recommend an oral antibiotic.

Prevention

• Unfortunately, even the best cared for equine can be infested by parasites. However, there are a few steps you can take to help prevent future infestation. Since parasites are easily transmitted, you should separate healthy horses from infected horses. According to Equine Science Update, it is possible for a horse to be infected with the mites without having any of the signs and symptoms of an infestation. Therefore, if you have a horse that is infested and has been around other horses, you should treat all horses accordingly. Another useful preventative is to help boost your horse's immune system. A strong immune system will not prevent infestations, but parasites are more likely to affect a horse with a compromised immune system. You can help boost an immune system with regular checkups and a healthy diet.
