Demodex Mange

Demodex Mange

This parasite called a “mite” generally lives in peace and harmony on all dogs in the skin. Infection from this parasite occurs when the body’s immune system is unable to maintain this harmonious state with the demodex parasite. This is considered a genetic or inherited trait, and affected animals should not be used for breeding.

Demodex is a genus of mite in the family Demodicidae. Demodex canis occurs naturally in the hair follicles of most dogs in low numbers around the face and other areas of the body.

Demodex mange has a red color and can be called a red mange. It has long, thin cigar like body with 8 legs. Demodex mange live in hair follicles and within the follicle. Because of the immune system. When dogs immune system is suppresed, the mange start increasing population. Bad shampoo and extended use of antibiotics and steroids are most common reasons for dogs demodicosis.

Demodex Mange Mites, Dust Mites and Sarcoptic Mange Mites these are mites problem created by pets. Ear mites aren’t usually referred to as “mange” but it is, in fact, our most common mite problem in pets. Suspect ear mites if your cat has blackish ear wax or is scratching at it’s ears.

Canine Demodectic Mange

Cases may not itch much at all.Mild demodex cases simply show up as small patches of hairlessness. More severe cases, though, often involve secondary bacterial skin infections making the the situation look a lot different; inflamed, pustular, itchy, and quite awful.

Demodectic mange

These diseases in humans are usually called demodicosis which may have a rosacea-like appearance. Common symptoms include hair loss, itching and inflammation. An association with pityriasis folliculorum has also been described.

Demodex mites which are normal skin inhabitants, but they are usually so low in number that you cannot tell that they are there. The mites live in hair follicles, and when they over multiply, they cause hair loss and secondary bacterial infections. Demodicosis is not contagious to other animals or to you.

Demodex Mites are transferred directly from the mother to the puppies within the first week of life. Transmission of the mites is by direct contact only. Lesions, if present, usually appear first around the puppy’s head, as this is the area most in contact with the mother. Virtually every mother carries and transfers mites to her puppies. Most puppies are immune to the mite’s effects and display no clinical signs or lesions. A few are not immune and it is these puppies that develop full-blown cases of mange.

lesions and signs of demodectic mange usually involve hair loss; crusty, red skin; and at times, a greasy or moist appearance. The mites prefer to live in the hair follicles, so in most cases, hair loss is the first noted sign. Usually, hair loss begins around the muzzle, eyes, and other areas on the head. The lesions may or may not itch. In localized mange, a few circular crusty areas will be noted, most frequently on the head and forelegs of young dogs 3-6 months of age.

Another type of mange mite, Sarcoptes scabei (var. canis), is the cause of sarcoptic mange better known as scabies. This mite burrows into the skin’s outermost layer and lays its egg. The eggs hatch, the larvae mature, and the emergent adult mites start the life cycle all over again. Scabies is highly contagious, and is one of the more common conditions that can be passed from dogs to people through direct contact.

Demodex LifeCycle

Demodex mite spends its entire life on the dog. Eggs are laid by a pregnant female, hatch, and then mature from larvae to nymphs to adults. The life cycle is believed to take 20-35 days.

Demodex Mange Treatment

We look for causes of immune suppression or stimulation of the sebaceous glands.We make sure the patient isn’t infested with worms, other parasites, or on a poor diet.Since patients with poor immune systems are susceptible to many diseases, we look extra hard for secondary infections,ringworm, and so forth.

Many demodex mange treatment creams and oimtments on the market today consist of chemicals and antibiotics. Besides antibiotics and chemicals, most demodex products have other inactive ingredients which block the skin pores. Another main problem with treatment of the Demodex mites is that the mites can quickly develop resistance to chemical and hormon substances which are composed in most prescribed treatments for mange. Treatment of demodex mange can be a lenghly process and may take long time. Antibiotics and chemicals can only be used for short 2-3 weeks period.
