Mycoplasma colonies were found on culture of synovial fluid in 14 of 18 cases of rheumatoid arthritis. It was possible to demonstrate the colonies in primary culture medium only by the method of hot water fixation and Giemsa staining. The organisms grown on solid medium were also observed electron-microscopically.
