  Demodex mite - Wikipedia, the free encyclopedia
The demodex mites form a genus of tiny parasitic mites which live in or near hair follicles of mammals.
Some species live on humans, for instance Demodex folliculorum which is primarily found in the hair follicles of the eyelashes and eyebrows, and Demodex brevis which lives in sebaceous glands connected to hair follicles.
The adult mites have a semi-transparent elongated body that consists of two segments and is between 0.1mm and 0.4mm long.

 Human Demodex Mites - Can They be Eliminated, Where Did It Come From?
Demodex Folliculorum, also know as Demodicids, are a species of tiny mite that some researchers have recently identified as a profound contributor to hair loss.
Demodex Folliculorum was first discovered in human hair by a researcher at Nioxin, a major hair-care and cosmetics manufacturer, thanks to a newly developed, hand-held, high powered microscope capable of magnifying the human scalp up to 1000 times.
Several Demodex mites can feast off of a single hair follicle, so the resulting effect is that there are just too many mouths to feed at the table, and the hair follicle eventually suffers.

 Demodectic Mange
Since almost all dogs have Demodex mites somewhere on their body but only a few have clinical signs of Demodex the theory is that dogs don’t have to be infected with the organism because they probably already have it.
In generalized Demodex there is a genetic defect that leads to an inability on the part of the dogs immune system to fight off this mite (in most cases).
The infestation of the Demodex mite is year-round.

 Mites Annoying Humans, HYG-2101-95
Some mites can be detected with a hand lens, while others require microscopic examination of skin scraping or even dust from vacuum cleaner bags.
Mite diagnosis is often difficult because specimens must be collected and identified by trained specialists before treatment can be made.
This barely visible mite completes development on the host bird (i.e., poultry, pigeons and starlings) and will leave the body of a dead host in large numbers to wander over walls, ceilings and bedding, seeking a new host.

Demodex mites feed on systemic yeast in the body, and the systemic yeast feed on the dietary yeast and/or sugar in the system (blood sugar).
Demodex mites take advantage of an immature or lowered immune system which is why the very young get it, and sometimes the very old or ill. A dog's immune system is not fully mature until at least one year, sometimes longer.
Okay, so now that we have established that demodex could not possibly be genetic, let me say that it is "congenital" in that a sub-standard immune system is passed on from the mother to the pups, and the mites can migrate to the pups from the mom shortly after birth.

Demodex brevis are obligatory parasites in the hair follicles and in the pilosebaceous glands.
The presence of mites was determined by microscopic inspection of secretion from sebum glands.
Conclusions: HLA A2 and Cw2 phenotypes have an important diagnostic, prognostic and pathogenetic significance and could have a possible role in resistance or susceptibility to demodicosis by regulating the end phase of the immune response (A 91).

 rosacea demodex mites treatment ?
As the Demodex mite is also present in many healthy individuals, it has been suggested that the mite may have a pathogenic role only when it is present in high densities.
We suggest that a certain mite density is not an appropriate criterion in the diagnosis of the disease; nevertheless, large numbers of D. folliculorum may have an important role in the pathogenesis of rosacea, together with other triggering factors.
Demodex seems to be a mediator of chronic blepharitis; we recommend that mites be sought in cilia of chronic blepharitis patients.

The hair follicle mites Demodex folliculorum and Demodex brevis and their role in the pathogenesis of rosacea have been the subject of much debate in the past.
We studied the prevalence of Demodex mites in facial skin biopsies obtained from 80 patients with rosacea, 40 with facial eczematous eruption and 40 with lupus erythematosus discoides.
The mite prevalence in the rosacea group (51%) was significantly higher than in the rest of the study population (eczema 28% and lupus discoides 31%).

With demodex, as with any other health issues displayed on these pages, it is best to get the opinion of your veterinarian and this is not a substitute for getting medical advice from a professional.

Juvenile (localized) demodex can be brought on as a result of the dogs immune systems inability to cope with the stress of teething, diet change, stressors in the the home environment, coming into heat, change of home, change of routine, early weaning from the dam, early or overly zealous vaccination program, and so on.
