, ear mites are one of the most common causes of otitis externa in both dogs and cats.
Formally known as Otodectes cynotis
, ear mites are small, barely visible mites that think your cat's ears are the perfect place to live.
These small parasites (otodectes cynotis
) are spread by cat to cat contact and they then spend their entire life on the cat.
Ear mite infection is usually caused by the parasite Otodectes cynotis
which are microscopic and therefore invisible to the naked eye.
It is also possible to suspect the presence of Otodectes cynotis
by the mess that they tend to make inside an infested animal's ear canal--a dark, crumbly accumulation of reddish-brown wax and mite debris that they continually generate and in which they characteristically wallow.
The factors mostly involved in producing otitis externa were: in 28 patients (52.8%) associated to ear conformation of certain breeds (ear type, hair in ear canal, number of apocrine glands, etc.), 9 canines (17.0%) due to atopia, 4 (7.5%) presented ear canal inflammation due to Otodectes cynotis
, 4 (7.5%) allergenic contact dermatitis and other factors in lower percentages (FIG.
In the letter, Lopez, a veterinarian in Westport, New York, described the results of a number of experiments he had conducted to determine whether Otodectes cynotis
, an ear mite usually found in cats and dogs, could also infest human beings.
is a mite of the family Psoroptidae, which lives predominantly in external ear canal.
Several types of ear mites exist, but the usual culprit in cats is Otodectes cynotis
. The microscopic parasite grows from egg to adult in three weeks and has about a two-month life cycle.
mites are non burrowing, white and active parasite reported worldwide in external auditory canal of cats, dogs, ferrets and other carnivores (Wilson and Zarnke, 1985; Wall and Sheearer, 2001).
