Ten strains of myocoplasmas were recovered from cultures of synovium or cultures inoculated with synovial fragments from rheumatoid arthritis and one from osteo-arthritis. The source of the organisms is not known. Patients with rheumatoid arthritis had no complement-fixing antibody and no fluorescent staining antibody against the mycoplasmas isolated and no(More)
When rheumatoid factor in rheumatoid arthritis and multiple sclerosis sera was titrated by the fluorescent antibody method on measles virus-infected cells, there was a marked and variable drop in titer on acetone-fixed cells as compared with unfixed cells. This was accounted for by the failure of measles virus hemolysin-inhibiting (HLI) antibody of the(More)
The synthesis and transport of the soluble antigen of influenza A virus were traced by immunofluorescent staining with human convalescent sera during abortive and complete infection of hamster BHK21 ceils and mouse L ceils. Times of synthesis in the nucleus, transport to the cytoplasm and extrusion by the cell were the same in complete and in abortive(More)
