Eyelash mites. Coloured scanning electron micrograph (SEM) of eyelash,or follicle,mites (grey,Demodex folliculorum) protruding from a dissected human hair follicle. These harmless parasites infest hair follicles (depressions in the skin which contain the roots of hairs) around the eyelids,nose and in the ear canals of humans. One follicle may contain up to 25 growing mites. They feed on oily secretions from the skin's sebaceous glands,as well as dead skin cells. Infestation with follicle mites is usually symptomless,but allergic reactions to the mites in susceptible individuals can cause hair loss and acne. Magnification: x180 at 6x7cm size | |
