Trichophyton rubrum is a dermatophyte fungus that primarily infects the skin, hair, and nails. It is one of the most common causes of superficial fungal infections in humans, particularly in the form of tinea pedis (athlete's foot), onychomycosis (nail infection), and tinea corporis (ringworm of the body). This pathogen thrives in warm and moist environments, making it prevalent in regions with higher humidity levels and among individuals who frequently engage in activities that cause sweating.
