Serological Diagnosis of Respiratory Viruses by the Single Radial Complement Fixation Test

Serological diagnosis of Bacteroides fragilis infections by a complement fixation test.

Paired specimens of serum from patients from whom Bacteroides fragilis had been isolated were tested by complement fixation against a crude B. fragilis antigen. A high titre or a rise in titre to B. fragilis was obtained in each of five patients with infection after abdominal surgery but in none of 11 patients with postpartum pyrexia nor in nine with vaginitis.

Quantitation of antibody to non-hemagglutinating viruses by single radial hemolysis: serological test for human coronaviruses.

A single radial hemolysis test was developed for quantitation of specific antibody to non-hemagglutinating viruses. With the human coronaviruses as models, this test utilizes the binding properties of the chromic cation to attach viruses to glutaraldehyde-treated sheep erythrocytes. The most satisfactory system consisted of stabilizing washed sheep erythrocytes with 0.0073% glutaraldehyde for 1...

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

A short, reliable, highly reproducible complement fixation test for the serological diagnosis of contagious equine metritis.

A complement fixation test, using round-bottomed microtitration plates and an 8 channel microdiluter, based on that used for brucellosis by Herr, Huchzermeyer, Te Brugge, Williamson, Roos & Schiele, 1985, has been developed for use on the sera of horses to detect antibodies to the contagious equine metritis organism. The results with 2 known positive sera tested 116 times in 27 separate tests w...
