brevis mites are associated with meibomian gland disease, also known as dry eye. The gland produces an oily substance that’s necessary to keep tears from evaporating. Meanwhile, the other species, Demodex brevis, burrows into meibomian gland to feed, often plugging up this crucial gland.
The combination of mites and bacteria causes blepharitis, a condition suffered by more than 20 million Americans, where the eyes become red, irritated and painful, and crusty debris builds up on the eyes. folliculorum typically carries Staphylococcus and Bacillus oleronius bacteria. The waste material the mites produce builds up as debris on the eyelids and causes inflammation. Then it feasts on the cells that line the follicle, sucking out their innards with a retractable needle in the middle of a round mouth. It uses a seven-clawed organ (a “palpus”) to grab hold of cells. One of the two species, Demodex folliculorum, buries itself face down near the roots of eyelashes.
These mites are microscopic parasites that live on eyelids and other parts of the face.
