Malassezia fungus infection
The different species of Malassezia inhabit the skins of a vast majority of adults without causing any particular harm or posing any danger.
In some individuals, the yeast suppresses the body’s response against the proliferation of the fungus. This leads to skin disorders, without the body producing an inflammatory response.
Irritating the metabolites of the yeast may also cause dermatitis, or irritation of the skin.
What causes Malassezia fungus infection?
Listed below are some factors that may cause Malassezia fungus infection:
- Humidity – This refers to the concentration of water vapor in the surrounding air.
- Oily skin – The yeast thrives in oily and humid environments, thus its marked appearance in the face, scalp, and upper trunk of the body.
- Sweating – Sweat gives the skin qualities that the yeast needs to proliferate.
- Immunodeficiency – Doctors have observed that immunodeficiency is a causative agent of Malassezia fungus infection. This is regardless of how the deficiency was attained, be it from immunosuppression medications, corticosteroids, or by way of an HIV infection.
- Acne and usage of oral antibiotics – Acne also plays a role in promoting an encouraging environment for Malassezia, especially when patients use products such as tetracyclines.
