RUBELLA INTERFERON AND FACTORS INFLUENCING THE INDIRECT NEUTRALIZATION TEST FOR RUBELLA ANTIBODY.

摘要: Summary Resistance of primary human amnion cultures to Sindbis virus was found correlate well with the presence specific rubella cytopathic effects. Certain exceptions this relationship were noted. interfering activity present in infected related interferon on basis chemical, physical and biologic properties. With indirect interference neutralization test for rubella, using challenge virus, cytopathology be a useful criterion determining optimum time challenge. The incorporation normal rabbit serum enhanced virus. Important factors contributing reliability results include use 10 or more TCID 50 than two per dilution tested. It is concluded that tests may reflect variety addition
