| |
| − | | |
| − | Mites are one of the most successful and divers vertebrate group. The species of veterinary importance are parasitic, although a few non-parasitic mites are also important, such as orbatid and forage mites.
| |
| − | | |
| − | Mites are very small, on average under 0.3mm in length and for this reason often go unnoticed. They spend the majority of their life cycle '''on''' the host and cause '''mange'''.
| |
| − | | |
| − | The taxonomy of mites is complex as there are over 8 families. In this article the families are split according to their location on the host into sub-surface (burrowing) and surface (non-burrowing) mites.

| |
| − | **Common among conventional rabbits; transmitted via contact.
| |
| − | *Clinical
| |
| − | **The ears are painful and itch intensely; affected rabbits shake their heads and scratch their ears. The inner surfaces of the pinnae are covered with brown, scaly, fetid material, and the skin beneath is raw. Mites are grossly visible.
| |
| − | *Pathology
| |
| − | **Histologically, there is chronic erosive and proliferative eosinophilic dermatitis. The mites are non-burrowing and thus are found only in the exudate, not in the tissue.
| |
| − | *Diagnosis
| |
| − | **Appearance; examination for mites (low magnification).
| |
| − | *Control
| |
| − | **Infestations are difficult to eliminate from a colony, although ivermectin is said to be effective.
