Demodex is a type of what organism?

Worm
Fungus
Mite
Bacteria

The correct answer is: Mite

Demodex is classified as a type of mite, specifically a parasitic mite that lives on the skin of mammals, particularly in the hair follicles. This genus comprises several species, with Demodex folliculorum and Demodex brevis being the most studied in relation to human hosts. These mites play a role in the skin's ecosystem; while they are typically harmless and exist in small numbers, an overgrowth can lead to skin issues, such as demodicosis, particularly in individuals with compromised immunity. Understanding the nature of Demodex as a mite helps in diagnosing and treating conditions associated with these organisms effectively.
