Mites in Cats, Dogs, etc (Mange, Acariasis, Scabies, Demodicosis)

Updated: Dec 14, 2021


Normal skin anatomy

Mange (demodicosis) refers to an inflammatory, parasitic skin condition of animals that is caused by increased numbers of microscopic mites that are normally present in low numbers in the hair follicles and sebaceous glands of the skin of otherwise healthy animals. The mites cause irritation of the skin, resulting in itching, hair loss, and inflammation and the condition is highly contagious. Though dogs and cats are very susceptible, horses and other domestic animals, as well as wild animals, including humans, can also be infected.


Human demodicosis caused by Demodex folliculorum

There are several types of mange that affect animals, and they include canine scabies (sarcoptic mange), ear mites (otodectic mange), walking dandruff (cheyletiellosis), and trombiculosis.

However, as a public health consideration, Demodex sp do not cross species barriers, i.e., they are species-specific. Generally, mites occur only on one type of host and a few closely related species, e.g. on canids such as dogs, wolves and foxes, but not on cats; or on cattle and buffaloes but not on sheep or goats, etc.

Species of Mites in livestock and pets

 

All species of mites occur worldwide. Demodex mite infestation usually remains asymptomatic but an important causative agent for many dermatological conditions.

  4. Notoedres cati affects cats; feline scabies, cat mange mite

  5. Cheyletiella spp., affects mainly cats, occasionally dogs; walking dandruff

  6. Pneumonyssoides caninum affects dogs; nasal mite

  7. Sarcoptes scabiei var. canis, affects dogs, canine scabies
