Question

"Ringworm" is caused by

B) dermatophytes that have invaded deep layers of the skin.
C) parasitic worms that infect the skin.
D) a hypersensitivity reaction caused by superficial contact with dermatophytes.
E) immunosuppression due to HIV infection.

Accepted Answer

Ringworm is caused by dermatophytes, which are fungi that grow in the upper dead tissue layers of the skin. They can also infect hair and nails, and are commonly found in damp places like locker rooms, swimming pools, and shared mats or towels. It is not caused by parasitic worms or hypersensitivity reactions, and while immunosuppression due to HIV infection can increase the risk of ringworm, it is not a direct cause.
