👉 Thyridanthrax is a bacterial infection that affects the skin, hair, and nails. It can be caused by the bacterium Mycobacterium thuringiensis (M.t.) or other bacteria that are resistant to antibiotics. Symptoms may include redness, itching, scaling, and pain in these areas of the body. Treatment typically involves broad-spectrum antibiotics, which are often administered intravenously or under local anesthesia.
