Immunological Study on Rickettsia sennetsu by Complement-fixation Test

Strain Variation of Rickettsia Orientalis in the Complement Fixation Test.

It is well known that Tsutsugamushi disease or scrub typhus in Japan has been prevalent in a limited northern district of the country, but Japanese investigators were not aware that there was a different type of scrub typhus in other parts of Japan, although some sporadic cases had been reported in the foothills of Mt. Fuji (Sakita, 1934), and Kanagawa Prefecture (Fukuzumi et al., 1950), which ...

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

Purification of complement-fixing antigens of Rickettsia sennetsu by ether treatment.

Soluble and particulate complement-fixing antigens of Rickettsia sennetsu were prepared from spleen suspensions of mice infected with the rickettsia and treated with cyclophosphamide. The medium used during purification of antigens, a solution consisting of equal volumes of phosphate-glutamate-sucrose buffer and veronal-buffered saline, was suitable for obtaining antigens with high titers and n...

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...
