The study on the genetic underlying of ear mites from
different species is the good example (Lohse et al.,
2002). As already noted, the persistence of genetic
underlying can be seen and the marker for the dog ear
mite species that can be seen in mites collected from
all infested species is “the second internal transcribed
spacer (ITS 2) of the rDNA” (Lohse et al., 2002).
However, some genetic markers can help differentiate
among ear mites from different species. A recent study
by Salib and Baraka (2011) showed that using the
RAPD-PCR could help discriminate between mites
from dog and cat. In the study by Salib and Baraka
(2011), three primers, H-12, T-20 and V-07 were used
and success in getting discriminating results could be
seen. With this knowledge, it might be helpful in
finding the source of mite in the uncommon infested
hosts such as human beings.
The use of molecular diagnosis for determination of
genetic marker can also be applied for the geo-
graphical epidemiology of the infestation. The good
example is the study on the distribution of ear mite
among foxes (Gunnarsson et al., 1991). Applying the
technique can help determine the original source of
infection within the region.
Conclusion
Dog ear mite infestation is an important parasitosis.
The role of molecular diagnosis seems to be limited at
present. However, it is no doubt that molecular
diagnosis can give usefulness in clinical practice
especially for the difficult-to-diagnose case and the
infestation in uncommon host.
