Fungal diseases are called mycoses and those affecting humans can be divided into four groups based on the level of penetration into the body tissues. (view-How Common are Fungal Diseases). 1  Superficial mycoses are caused by fungi that grow on the surface of the skin or hair.2  Cutaneous mycoses or dermatomycoses include such infections as athlete's foot and ringworm, where growth occurs only in the superficial layers of skin, nails, or hair.Subcutaneous mycoses penetrate below the skin to involve the subcutaneous, connective, and bone tissue.utaneous mycoses or dermatomycoses include such infections as athlete's foot and ringworm, where growth occurs only in the superficial layers of skin, nails, or hair. Subcutaneous mycoses penetrate below the skin to involve the subcutaneous, connective, and bone tissue.
Chapter 10 - Infectious Diseases 217 Chapter 10 - Lesson 1 Causes of Infectious Diseases Introduction Infectious diseases are caused by exposure to living organisms not normally present in the animal.ungal diseases may also be called mycosis or mycotic diseases. Some fungi infect the superficial layer of skin (such as the ringworm fun-gus), and others invade various body systems (such as the aspergillus fungus). Parasites Common parasitic diseases of animals are caused by arthropods, worms, and protozoa.
