If you search for demodex using Google’s Scholar search, you will find over 8,000 papers that mention them.
Further if you search for demodex and rosacea you will get nearly 2,000 results. So there has been plenty of research into the topic.
Whilst a clear causal link between the mites and rosacea has not yet been found, we do know a lot about demodex mites, and perhaps some clues about a link.
Demodex Mites Trivia
Here for your trivia pleasure, is a list of what research has uncovered about demodex mites, all backed up by research, not just internet rumours … The following are taken from a great paper - The potential role of Demodex folliculorum mites and bacteria in the induction of rosacea, Journal of Medical Microbiology, August 2012 [ref].
See how many of the following statements you already knew.
- There are 100 species of demodex and all are specific to the animal they live on.
- In many cases in the infestation of demodex mites is without any symptoms and overall their role remains a mystery.
- The disease-causing role of demodex is understood in dogs where demodex canis can cause demodicosis, a serious disease.
- Only two types of demodex are found on human skin – demodex folliculorum and demodex brevis.
- Demodex Folliculorum is around 0.3 to 0.4 mm long, and live in hair follicles.
- Demodex Brevis is only 0.2 – 0.3 mm long, and live in the sebaceous or meibomian glands.
- D. Brevis is more difficult to extract as it lives deeper in the skin.
- Demodex avoid sunlight.
- The life cycle of a mite is from 14 to 18 days.
- Demodex is found in all races of peoples in all geographic areas
- New born babies do not have demodex mites, colonisation of the skin takes place in childhood or early adulthood.
- D. folliculorum counts are a lot more more per person, but D. brevis are found in larger areas of the body.
- Men typical have 4 times as many D.F as D.B, but women typically have 10 times as many D.F as D.B
- Mite density is very low in young adults, even though their levels of sebum are high – a potential source of food.
- Papulopustual rosacea sufferers produce sebum with an altered fatty acid profile that may appeal to the mites.
- Both forms of human demodex mites have 4 pairs of legs.
- When the mites emerge at night to eat, they move at a rate of about 16 mm per hour.
- Originally it was thought that the mites and humans had a close relationship where they happily lived together, but that thinking has been slowly changing over the years.
- Rosacea sufferers can have a density of around 10 mites per square cm, whereas healthy skin has around 0.7 mites per square cm.
