Two species of Demodex mites can live in human hair follicles of the eyelashes, and although they are usually benign (harmless), they may start to multiply in the population in response to a weak immune system or advanced age. Their eggs and decomposing bodies clog glands (pores), causing blepharitis (a nasty eye infection).
Demodex mites can affect Eyelashes and Eyebrows
Chronic blepharitis is resistant to conventional treatment and maintained/treated by topical corticosteroids (a prescription cream). Effective action is often difficult around the eyes due to their sensitive nature, and also due to their hospitable living conditions for Demodex mites. The temperature, water/fluid availability and ph levels are perfect. Where for example a persons bum cheeks may often be too cold, or hands are often exposed to adverse chemicals, the eyes are often at the same ph, temperature and moisture content.
The results published by a team at the department of biology in the national University of Ireland, Maynooth suggests that a bacterium (germs), Bacillus oleronius (their fancy name) whose characteristic is to develop on Demodex mites, could play a role important characterizes inflammatory rosacea. In other words the germs on Demodex mites may also give you a rash too.
They have discovered that the presence of this bacterium (germ) stimulates an immune system response in 79% of 22 patients with rosacea (with papulo-pustules…spots), whereas such response was observed in 29% of 17 subjects without the condition. Moreover, the study authors note that this bacterium could explain the effectiveness of antibiotics used to fight against rosacea. Indeed, so far only the anti-inflammatory properties of these antibiotics could explain their positive effects on the symptoms of rosacea since no bacteria had never been suspected of involvement in this disease.
Hair Loss from Demodex Mites
The authors of the study, the fact that only some antibiotics are effective against rosacea while many have anti-inflammatory properties suggests that a bacterial agent may be involved. Moreover, the researchers could prove that the antibiotics traditionally used in the treatment of rosacea (tetracycline, doxycycline and minocycline) had a destructive effect on the battery studied which would reinforce the hypothesis of the role of this bacterium in rosacea.
Human Demodex infestation is manifested by lesions (sore patches) of folliculitis (infected pores), small crusty erythematous plaques (scabs), with or without papulo-pustules (yellow head spots). They predominate (hang around) in the face area and sit on the cheeks, nasolabial folds (cheek/nose folds), forehead and chin. They are found most often on the scalp or chest.
Its role in the perioral dermatitis (a rash) and folliculitis (infected pores) and in some cortisone is discussed. Some authors incriminate Demodex awareness, especially in the form of granulomatous rosacea (a nasty rash). The symptoms are related to an abnormal immunological reaction with sensitization to these mites, much more than a toxic reaction. In other words you will have Demodex problems on your body if your body reacts badly to the mites.
Demodex Mite can be found any where on human body
Several cases of Demodicidosis have been described in both sexes, in children or immunocompetent adults (ill people), and diabetic patients, in individuals undergoing chemotherapy for cancer or leukemia, or of acquired immunodeficiency syndrome. It is in these cases where the unlikely event of Demodex infections causing damage on the body to become more likely. There are very few places on the human body which are hospitable enough for a large enough infestation to result in damage to the skin. This however may happen on the body if the sufferer is in one of the pre-mentioned disadvantages.
