Indirect haemagglutination test using gonococcal pilus antigen: how useful to diagnose gonorrhoea?

In 1979 an indirect haemagglutination test (gonococcal antibody test) using gonococcal pilus antigen replaced the gonococcal complement fixation test as our routine procedure to show gonococcal antibodies. In the diagnosis of current gonorrhoea the sensitivity of the gonococcal antibody test was far superior to that of the gonococcal complement fixation test (about 55% versus 9% for first episo...

Study of a passive haemagglutination test for gonorrhoea.

Modified erythrocytes in indirect haemagglutination with Neisseria gonorrhoeae antigen.

Antigen prepared from gonococci by extraction with alkali has the ability to sensitize erythrocytes for agglutination or indirect haemolysis by corresponding antisera (Chanarin, 1954; Maeland, 1966; Thomas and Mennie, 1950). These indirect techniques have been used for the study of endotoxin preparations from gonococci. Endotoxins, however, require treatment with alkali before sensitization, ex...

Gonococcal Complement-fixation Test in Complicated and Uncomplicated Gonorrhoea.

The complement-fixation reaction with gonococcal antigen (gonococcal complement-fixation test: GCFI) is based on the same serological principle, and has been known for about as long, as the Wassermann reaction. Up to the 1940's the GCFT was widely employed, but as improvements in cultivation techniques for gonococci were developed, interest in the complement-fixation reaction diminished. At pre...
