Diseases - Mange
Terms in this set (15)
Mange is a skin disease caused by
Mites. It effects nearly every mammalian species.
There are numerous species of mites that prefer specific mammal species, but most cases observed are
Demodectic, Sarcoptic, and Cheyleteillosis.
Sarcoptic Mange caused by
Sarcoptes scabiei or other variations of sarcoptes mite.
Demodex mite resides in the
sebaceous unit of the animal
(Cheyletiellosis) walking dandruff is caused by teh
Cheyleteilla mites, which live on the hair and fur, only visiting the skin to feed.
Sarcoptic Mange is observed through examination of the skin.
Infected tissue will be inflamed, lesions, postules, and alopecia can also be seen.
Clinical signs of Demodex infestation are varia le. Generalizwed demodicosis is defined by
focal lesions, or multiple body regions affected. Usually patchy alopecia is absorved.
Demodex - Affected skin can present silver-greyish scaling, lichenified, pustular or ulcerated as well from superficial or deep pyodermas.
*Systemic signs of demodex may be seen if secondary bacterial sepsis develops.
*Infestations of demodex can also be characterized by greasy seborrhea "dandruff" over the dorsum of the trunk.
Cheyletiellosis - walking dandruff is given the name because
mites are visible and appear to be moving dandruff.
If treatment is neglected, the animal infected can succumb to anemia, latent infections and can eventually die. After diagnossis, treatment of Sarcoptic mange is simple and effective.
An over-the-counter miticide or kennel dip can be used, pet owners should also discard bedding and treat areas where the animal has been.
After diagnosing Demodex, treatment was once
an incredibly difficult process, intact dogs need to be neutered/spayed (estrus or pregannacy can trigger relapses).
Demodex - Systemic antibiotics along with ivermectin would be used weekly. Weekly baths with benzyol peroxide proved to work as well.
Thankfully, with new medicine, Demodex can be treated off-label with Bravecto.
Cheyletiellosis - walking dandruff is a mild parasitic form of infeciton, treated much like
Sarcoptic mange with topical miticide products. These treatments should be repeated bi-weekly to ensure that the life cycle of the mite is broken.
Prevention is done first by simply maintaining your animals heath. Animals are more susceptible to this skin disease if they tend to
roam with other animals, are often boarded, are at a shelter, and have constant contact with other animals.
Prevention includes routine use of flea and tick prevention. Also if a pet is to become infected, then the animal should be
isolated from others if they are present and treated immediately.
