THE IMMUNOLOGICAL RESPONSE TO INFLUENZA VIRUS INFECTION AS MEASURED BY THE COMPLEMENT FIXATION TEST

The Immunological Response to Influenza Virus Infection as Measured by the Complement Fixation Test

A quantitative complement fixation test with influenza immune sera and virus antigens obtained from allantoic fluid is described. The method utilizes a photoelectric densitometer which provides a simple, objective, and accurate determination of the hemolytic reaction. The enhancement of the hemolytic activity of complement in the presence of serum or allantoic fluid necessitates a preliminary t...

A Specific Complement-fixation Test for Infection with Poliomyelitis Virus

A complement-fixing antigen has been developed, using as source of material CNS tissue from newborn mice infected with the newborn mouse-adapted strain of the Lansing type, MEF1 virus. With this antigen, specific reactions have been obtained with sera from mice, cotton rats, and monkeys immunized with the Lansing-type virus, and from monkeys and chimpanzees convalescent from infection with this...

Detection of rotavirus by Latex Agglutination Test (Rotales); Comparison with Electron Microscopy and Complement Fixation Test

The immunological response of foetal mice to influenza virus.

Since the introduction of the "self-marker" hypothesis of antihody production by Burnet and Fenner (1949) and the experiments of Billingham, Brent and Medawar (1953) on the production of actively acquired tolerance in mice to skin homografts from a different strain, there has been a great deal of interest in the immunological behaviour of animals exposed in utero to a variety of antigens. Burne...

Survey of influenza antibody in England by the strain-specific complement-fixation test.

The first recorded case of recovery from hepatic coma after an exchange blood transfusion was that of Lee and Tink (1958). They gave two exchange transfusions of fresh blood to a boy aged 13 who was deeply jaundiced and comatose. After the first transfusion of 3,260 ml. his condition was unchanged, but when a second exchange of 3,140 ml. was given he improved and recovered completely. Trey et a...
