Which of the following skin conditions is NOT a fungal infection?

Folliculitis is identified as not being a fungal infection because it is primarily an inflammatory condition that affects hair follicles, typically caused by bacteria, particularly Staphylococcus aureus, or irritants. It often presents as small, red bumps or pimples around hair follicles, and while it can sometimes be caused by fungi, the most common causative agents are bacterial. In contrast, dermatophyte infections, candidiasis, and histoplasmosis are all associated with fungal pathogens. Dermatophyte infections arise from fungi that infect the skin, hair, or nails. Candidiasis is caused by Candida, a type of yeast, while histoplasmosis results from the inhalation of fungal spores. Understanding these distinctions is important for proper diagnosis and treatment in medical administrative practices.
