Lectins agglutination test as an epidemiological marker for Neisseria gonorrhoeae.

Lectins agglutination test as an epidemiological marker for Neisseria gonorrhoeae.

Stable serum resistance of Neisseria gonorrhoeae as an epidemiological marker.

Using a simple and rapid microassay, we tested 100 strains of Neisseria gonorrhoeae isolated from 81 patients (41 men and 40 women) for their sensitivity to killing by normal human serum (NHS). The reproducibility of the test was good when the bactericidal end points were taken as the dilution of fresh NHS that killed more than 95% of the test organisms. The bactericidal end points of strains i...

Nuclease enhancement of specific cell agglutination in a serodiagnostic test for Neisseria gonorrhoeae.

Antiserum to a purified type R lipopolysaccharide antigen isolated from Neisseria gonorrhoeae was used in a slide agglutination test and compared with conventional carbohydrate utilization and fluorescent antibody tests to confirm the identity of laboratory cultures classified as typical or "atypical" N. gonorrhoeae. Cultures of Corynebacterium vaginalis, N. meningitidis, N. catarrhalis, N. sic...

Identification of Neisseria gonorrhoeae from primary cultures by a slide agglutination test.

Hen antigonococcal lipopolysaccharide hen serum was used in a simple slide agglutination test for the identification of Neisseria gonorrhoeae from primary isolates.

Wheat-germ agglutination of Neisseria gonorrhoeae. A laboratory investigation.

Wheat-germ agglutination (WGA) was used to identify 168 strains of Neisseria gonorrhoeae and 105 strains of other Neisseria species in a routine laboratory. About one-third of the meningococci reacted with the lectin and titres with some organisms varied on repeat testing. The technique is regarded as unreliable for the identification of Neisseria species.
