Microbiology Practice Exam

Question: 1 / 400

Which fungi are primarily responsible for fungal infections in humans?

Yeasts

Molds

Dermatophytes

Dermatophytes are a specific group of fungi that are primarily responsible for infections of the skin, hair, and nails in humans. These fungi thrive in keratin, a protein found in these tissues, and they cause a range of superficial infections known as dermatophytoses, which include conditions such as athlete's foot, ringworm, and jock itch.

While yeasts and molds are also significant in human mycoses, dermatophytes are specifically adapted to infect keratinized tissues, making them the primary agents for such dermatological fungal infections. Yeasts, such as Candida, can cause systemic and opportunistic infections, and molds can lead to various infections, particularly in immunocompromised individuals. Protozoa, although important in certain infections, are not fungi and do not fit within this context of fungal infections.
