Ear mites are mites that live in the ears of animals. The most commonly seen species in veterinary medicine is Otodectes cynotis (Gk. oto =ear, dectes =biter, cynotis =of the dog). This species, despite its name, is also responsible for 90% of ear mite infections in felines.
The mite is 0.4 mm (0.016 in) in size, [2] approximately the size of a grain of salt, and can be seen with the naked eye. [5] It lives in the external ear canal of its host, and causes intense irritation leading to otitis externa. [2] The lifecycle of O. cynotis takes approximately three weeks. [1]

The microscopic mite Lorryia formosa (). The mites are not a defined taxon, but is used for two distinct groups of arachnids, the Acariformes and the Parasitiformes.The phylogeny of the Acari has been relatively little studied, but molecular information from ribosomal DNA is being extensively used to understand relationships between groups.
Psoroptidae is a family of parasitic mites, [2] which are 1–2 mm (0.039–0.079 in) long and live on the surface of the skin, rather than burrowing into it. [3] These mites affect various species, including cats, dogs, rabbits, cattle, sheep, and horses, causing skin inflammation, scabs, crusting, and hair loss.
Infections can be caused by both bacterial and fungal origin, as well as small organisms such as ear mites. Malassezia pachydermatis is a common fungal agent for ear infections in dogs. Staphylococcus intermedius is the most common bacterial infection. A more serious ear infection, with pus in the ear, may be caused by Pseudomonas aeruginosa.
The avian mite Dermanyssus gallinae can also infest various parts of the body, including the ear canal and scalp. Diagnosis is challenging due to the mites' size, requiring microscopic identification by a medical entomologist, and the clinical symptoms often mimic other conditions, such as scabies or allergic reactions. The atypical or delayed ...
Demodex / ˈ d ɛ m ə d ɛ k s / is a genus of tiny mites that live in or near hair follicles of mammals. Around 65 species of Demodex are known. [2] Two species live on humans: Demodex folliculorum and Demodex brevis, both frequently referred to as eyelash mites, alternatively face mites or skin mites. [3] Different species of animals host ...
