Understanding the Culprits
Dermatophytes are fungi that thrive on keratin, a protein found in skin, hair, and nails. The three main types of dermatophytes are Trichophyton, Microsporum, and Epidermophyton. These pesky fungi can cause a range of infections depending on where they strike.
Spotting the Symptoms
Dermatophyte infections have various subtypes like tinea pedis (athlete's foot), tinea corporis (ringworm), and tinea unguium (nail infection). Each subtype has unique symptoms, such as itchy, scaly patches or discolored nails, making diagnosis crucial.
Diagnosing Dermatophyte Infections
Diagnosing these infections often involves a physical exam and tests like a potassium hydroxide (KOH) preparation. This test helps detect fungal elements in skin scrapings, providing a quick confirmation of the infection.
