Study Notes
Fungal Infections
- The study of mycoses of man and their etiologic agents is called medical mycology.
- The property that is NOT characteristic of the kingdom of Fungi is mobility.
- The cell wall of fungi contains polysaccharides such as chitin and glucans.
- Ergosterol is a component of the cell membrane and is a site of action of some antifungal drugs.
- The primary reason for the increasing fungal infections in humans is the growing number of immune-compromised patients.
- Fungi can be classified based on their growth forms, such as yeast or mold.
Characteristics of Fungi
- Yeast is characterized by its ability to reproduce by budding.
- Fungi that form branching tubular filaments called hyphae are known as molds.
- Dimorphic fungi occur in two forms: yeast form in tissues or when grown at 37°C, and filamentous form when grown at 22°C.
- Mycelium is the vegetative part of the fungus, consisting of a mass of branching hyphae.
Fungal Infections and Toxins
- Histoplasma capsulatum is a fungal species commonly found in soil and pigeon feces, and can initially infect the lung and brain.
- Cryptococcal meningitis is a fungal infection characterized by rapidly fatal outcomes in immune-compromised hosts.
- Inhaled spores and volatile fungal toxins can produce allergic manifestations such as asthma and allergic rhinitis.
- Certain strains of fungi can produce toxic compounds such as aflatoxins, which can lead to poisoning if ingested.
- Aflatoxin B1 is a potent carcinogen that can induce mutation in the p53 human suppressor gene.
Fungal Threats
- Invasive aspergillosis is a type of fungal infection that is a growing threat to human health, especially in immune-compromised patients.
- Fungal infections are a growing threat to human health, especially in patients with compromised immune systems.
