  • Acne - skin lesions caused byconditionally pathogenic parasite of the genus Demodex mites. Demodex lives in the hair follicles, sebaceous glands in the skin, glands century. Mites are microscopic and not visible to the naked eye.

    The speed of movement of demodex on the skin - 8-16 mm / hour. It feeds on sebum.

    reproduction
    ticks stops outside the host. At t ° + 30 °, + 40 °, they
    show maximum activity and, therefore, often worsening demodectic
    It occurs in the spring and summer, in the period of maximum temperature,
    after taking a hot bath, a long stay in the hot room

    Live kill them instantly, 96 ° alcohol - in 3-4 minutes, 10 °
    alcoholic solution of salicylic acid - 1 minute.



    What causes demodectic

    tongs

    It does not arise at all. Men and women are equally common demodekoz
    often. It is considered normal number of ticks 0-1, sickness -
    3-4 tick more 6 eyelashes.

    As a result, long-term
    co-existence between mites and host develops
    stable equilibrium (carrier) in which the effects of the parasite
    balanced by a healthy immune mechanisms carrier host. Under
    the influence of various factors, the equilibrium is disturbed and there
    manifestations of demodectic mange. The external factors provoking occurrence
    demodectic mange include: exposure to high temperatures, solar
    exposure, adverse conditions for household and professional use, operation
    on the eyeball. The internal factors contributing to the emergence of
    demodectic mange include changes in the patient's organism immunity
    result of diseases of the nervous, cardiovascular and hormonal (eg,
    diabetes) systems, gastrointestinal and liver disorders
    in metabolic processes, reduce immunity.

    Sveeeudalennuyu eyelash for research is placed on a glass slide,
    Pour 10-20% solution of caustic alkali, gasoline, kerosene or
    glycerol coated glass slide and examined under
    microscope.
