Abstract:
The incidence of invasive mycoses is increasing, especially among patients who are immunocompromised or hospitalized with serious underlying diseases. Such infections may be broken into two broad categories: opportunistic and endemic. The most important agents of the opportunistic mycoses are Candida spp., Cryptococcus neoformans, Pneumocystis jirovecii, and Aspergillus spp. (although the list of potential pathogens is ever expanding); while the most commonly encountered endemic mycoses are due to Histoplasma capsulatum, Coccidioides immitis/posadasii, and Blastomyces dermatitidis. This review discusses the epidemiologic profiles of these invasive mycoses in North America, as well as risk factors for infection, and the pathogens' antifungal susceptibility.
Insights
Invasive fungal infections are rising, particularly in vulnerable patients. This review details North American epidemiology, risk factors, and antifungal susceptibility for key opportunistic and endemic mycoses.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Epidemiology
Background:
- Invasive mycoses incidence is increasing globally.
- Immunocompromised and hospitalized patients are at highest risk.
- Infections are categorized as opportunistic or endemic.
Purpose of the Study:
- To review the epidemiologic profiles of invasive mycoses in North America.
- To identify key risk factors for these infections.
- To analyze antifungal susceptibility patterns of common fungal pathogens.
Main Methods:
- Literature review of invasive mycoses in North America.
- Analysis of epidemiological data for opportunistic and endemic fungi.
- Summary of current knowledge on risk factors and antifungal resistance.
Main Results:
- Key opportunistic pathogens include Candida spp., Cryptococcus neoformans, Pneumocystis jirovecii, and Aspergillus spp.
- Common endemic mycoses are caused by Histoplasma capsulatum, Coccidioides spp., and Blastomyces dermatitidis.
- Data on risk factors and antifungal susceptibility are presented for these agents.
Conclusions:
- Understanding the epidemiology and risk factors is crucial for managing invasive mycoses.
- Antifungal susceptibility data informs treatment strategies.
- Continued surveillance is necessary due to the expanding list of potential pathogens.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
