Ringworm is a disease of the skin caused by the invasion of 

 the hair shafts, hair follicles and epidermis with the vegetable 

 fungus known as Tinea tonsurans or Trichophyton tonsurans. It 

 attacks more commonly cattle and dogs, but also horses, pigs, sheep, 

 goats, cats and poultry. The disease is capable of being trans-
