Malassezia is a genus of fungi responsible for various skin diseases. It is pronounced as /ˌmæləˈsiːziə/, with four syllables. The word is spelled with a "M-a-l-a-s-s-e-z-i-a," with two "s"s and "z" in the middle. This spelling is derived from the name of the French physician Louis-Charles Malassez who was first to describe the fungi. The spelling has remained the same since the discovery, and it is widely used in medical literature to describe the fungal species responsible for skin infections.
Malassezia is a genus of fungi that encompasses various species commonly found on the skin of humans and other animals. It is a type of yeast-like fungus that belongs to the family Malasseziaceae. These fungi thrive in areas of the body with higher oil production, such as the scalp, face, and upper trunk.
The presence of Malassezia on the skin is usually harmless, as it is part of the natural flora. However, in certain circumstances, these fungi can overgrow and cause various skin conditions. These include dandruff (seborrheic dermatitis), pityriasis versicolor (a common fungal infection causing discolored patches on the skin), and folliculitis (inflammation of hair follicles). People with compromised immune systems or certain genetic predispositions may be more susceptible to developing these conditions.
Malassezia feeds on the sebum or oil produced by the skin, which contributes to its ability to cause these skin conditions. Additionally, it has been suggested that an overgrowth of Malassezia may trigger an inflammatory response from the immune system, leading to the symptoms observed in these conditions.
Treatment for Malassezia-related skin conditions typically involves the use of antifungal medications, such as topical creams or shampoos. These medications are designed to target and eliminate the fungi, thereby alleviating the symptoms.
Overall, Malassezia is a fungal genus that typically resides on the skin without causing harm but can lead to specific skin conditions in certain situations.
The word "Malassezia" has a Greek origin. It is derived from the Greek words "malasso" meaning "soften" or "make smooth" and "sezō" meaning "to cause to boil". Thus, "Malassezia" essentially means "causing to soften or boil".
