Abstract
Dog ear mite infestation is an important ear parasitosis. This infestation is an important common parasitosis in dog and
can also be seen as zoonosis to human beings. The diagnosis of dog ear mite is very important since early diagnosis means success in
case management. Here, the author briefly reviews and discussed on the role of molecular diagnosis for dog ear mite infestation
.

Introduction
Dog ear mite infestation is an important ear parasitosis
(van Bers, 2001). This infestation is an important
common parasitosis in dog (Harvey, 1980) and can
also be seen as zoonosis to human beings (Wiwanitkit,
2012). Generally, ear mite is classified as an insect.
The mite is a very small parasite that can live in the
dark recesses of ear canals. It might be visible by
naked eye. The parasite can cause the problem within
ear canal and also produce itching sensation to the
skin around the ear (van Bers, 2001).
The infested dogs can present with itching sensation,
scratching on the ears and heads (van Bers, 2001).
This might result in bleeding presentation (van Bers,
2001). The poor sanitation is the important risk factors
for developing dog ear mite infestion (Rodriguez-
Vivas et al., 2003). In dogs with pruritic ear
dermatoses, around 40% present the dog ear mite
infestation (Park et al., 1996).
1 Diagnosis of dog ear mite infestation
As noted, dog ear mite can be detectable by naked eye.
The observation of the intraauricular canal mite is
usually the presumptive diagnosis. This can be done
by using the otoscope. Sometimes, the mite can be
detected in the samples from skin scrapping from
itching lesions. The diagnosis of dog ear mite is very
important since early diagnosis means success in case
management. In general, the confirmation of diagnosis
is by the parasitological examination of the determined
mite. The main cause of infestation is the parasite
namely Otodectes cynotis. Briefly, this mite is short
and it has unsegmented pedicels and suckers on the
end (Grono, 1969). The morphology of the parasite
from different host species, dog and others, is usually
the same (Lohse et al., 2002).
However, the diagnosis might be difficult sometimes.
The use of immunological diagnosis might help
support the diagnosis (Powell et al., 1980). This is
usually used in cases with unexplained dermatoses.
However, with the implementation of the new
advanced molecular diagnosis approach, the use of the
new technique in dog ear mite is very interesting. Here,
the author will further briefly review and discuss on
the role of molecular diagnosis for dog ear mite
infestation.
2 Role of molecular diagnosis for dog ear
mite
infestation
The role of molecular diagnosis for dog ear mite
infestation is very limited at present. The reason might
be due to the fact that this disease can be easily
detected by classical approach. However, there are
some reports on using molecular diagnosis technique
research on dog ear mite infestation. The interesting
application is on the evolutionary biology research.
