A comparison is made of serological diagnostic procedures used for infectious bovine rhinotracheitis in the European Community. A panel of 65 sera, including positive, doubtful, negative and diluted samples was dispatched to nine different European laboratories and tested by neutralisation, enzyme-linked immunosorbent assay (ELISA), indirect immunofluorescence and passive haemagglutination, acc...
Using the leucocyte migration inhibition (LIF) test we looked for evidence of cell-mediated hypersensitivity against myoglobin in 8 patients with polymyositis (PM) or dermatomyositis (DM). The migration index for PM-DM patients was 47.5 +/- 17%, while in the controls the index was 86 +/- 12% (p less than 0.001). The presence of serum antibodies against myoglobin was also investigated by passive...
SYNOPSIS Sheep red cells, sensitized with a genus-specific leptospiral substance extracted from a water leptospira, were preserved by freeze drying. The serological reactivity of the preparation was tested against a total of 41 sera from proven cases of human leptospirosis and 27 from proven cases of animal leptospirosis. The sensitized, freeze-dried red cells appeared to be a sensitive reagent...
IgM rheumatoid factor was assayed by three routine methods: latex fixation; haemagglutination; and end point laser nephelometry in 69 patients with definite or classical rheumatoid arthritis and 58 patients with other non-rheumatoid arthropathies, selected prospectively according to the American Rheumatism Association clinical criteria. The operators of the assays were unaware of the clinical d...
