Feedback:
Ringworm is caused by a fungal infection. Fungi include yeasts and molds, which cause infections in the skin, mucous membranes, hair, and nails. Rickettsiae are microorganisms that resemble bacteria but cannot survive outside of another living species. They are responsible for Lyme disease. Protozoans are single-celled animals classified according to their ability to move. They do not cause ringworm. Helminths are infectious worms that may or may not be microscopic. They include roundworms, tapeworms, and flukes.
