Final answer:
Tinea pedis, or athlete's foot is the most common foot infection from nail services and is caused by dermatophytes treated with antifungal medications.
Step-by-step explanation:
The most frequently encountered infection on the foot resulting from nail services is Tinea pedis, commonly known as athlete's foot. This infection is caused by fungi known as dermatophytes, specifically the genus Trichophyton. These fungal pathogens affect the skin of the foot, especially between the toes, leading to itching, redness and a distinctive ring-shaped rash.
Athlete's foot is considered a type of ringworm though it's not caused by an actual worm but by fungus. The condition is generally treated with topical antifungal creams and powders but more persistent cases might require prescription oral medications. Poorly-ventilated footwear and moist environments can exacerbate this condition thus care should be taken especially after receiving nail services to ensure feet stay dry and clean.
