primarily dermatophytes

Nail fungus, also known as onychomycosis, is a common fungal infection that affects the nails. It is caused by various types of fungi, primarily dermatophytes, which thrive in warm and moist environments. Nail fungus can occur on both fingernails and toenails, but it is more commonly seen in toenails.Symptoms of nail fungus may include thickened, discolored (yellow, brown, or white) nails that may become brittle or crumbly. In some cases, the affected nail may detach from the nail bed, causing pain or discomfort. The infection can spread from one nail to another or even to other parts of the body if left untreated.
