Study Notes
Fungal Infection Entry Mechanisms
- Fungi access the body through various portals of entry.
- A common initial exposure for humans is to the yeast Candida albicans during childbirth, encountered in the vaginal canal.
- Malassezia furfur is frequently found in areas with abundant sebaceous glands (e.g., skin).
- Generally, fungi do not cause disease in healthy individuals with strong immune systems, despite constant exposure.
- Infection occurs when fungi breach barriers like unbroken skin and mucous membranes.
- Fungi enter tissues through traumatic implantation or inhalation.
