Abstract
Abstract It is believed that rheumatoid arthritis and related collagen and auto-immune diseases are an infection and that various species of free-living (limax) amoebae are the aetiological agent of these diseases. It has been discovered that furazolidone is effective for the treatment of rheumatoid arthritis and other collagen and auto-immune (rheumatoid) diseases.
