What causes systemic fungal infections?
Fungi that can cause systemic infection in people with normal immune function as well as those who are immune-compromised, include: Histoplasma capsulatum (causing histoplasmosis) Coccidioides immitis (causing coccidioidomycosis) Blastomyces dermatitidis (causing blastomycosis)
How are systemic fungal infections treated?
Systemic candidiasis is usually treated with oral or intravenous (IV) antifungal medications, including echinocandin (caspofungin, micafungin, or anidulafungin) fluconazole, and amphotericin B.
What are systemic fungal infections?
Systemic fungal infections usually originate in the lungs (aspergillosis and other mould infections as a result of inhalation) or from endogenous flora (candidaemia as a result of infected lines or leakage from the gastrointestinal tract), and can spread to many other organs.
Which of the following is most likely to be an opportunistic fungal infection?
Cryptococcosis. Cryptococcosis is most typically an opportunistic fungal infection that most frequently causes pneumonia and/or meningitis.
What are systemic antifungals?
Systemic antifungals are either fungicidal (kill the fungus) or fungistatic (inhibit fungal growth). Drugs for systemic antifungal treatment include: Polyene macrolides (e.g., amphotericin B and its lipid formulations) Various azole derivatives (fluconazole, isavuconazole, and itraconazole)

Can a fungal infection be systemic?
Fungal infections in humans can be broadly divided into superficial infections of the skin and mucosae, and deep, systemic or disseminated infections such as candidaemia and invasive aspergillosis.
What are the 5 virulence factors of the pathogenesis of the fungi?
Virulence factors that promote fungal colonization of the host include the ability to:
- adhere to host cells and resist physical removal;
- invade host cells;
- compete for nutrients;
- resist innate immune defenses such as phagocytosis and complement; and.
- evade adaptive immune defenses.
