Preservation of Neisseria gonorrhoeae by the gelatin-disc method.

A simple manganous chloride and Congo red disc method for differentiating Neisseria gonorrhoeae from Neisseria meningitidis.

Manganous chloride and Congo red incorporated into blotting paper discs have been used to differentiate gonococci from meningococci. The new technique is simple and reliable; the materials for the test are inexpensive. The method will increase the efficiency of distinguishing between the pathogenic Neisseria in any clinical bacteriology laboratory and especially in those in the tropical areas.

RealLine Neisseria gonorrhoeae Fla-Format ASSAY KIT FOR THE QUALITATIVE DETECTION OF NEISSERIA GONORRHOEAE DNA BY REAL-TIME PCR METHOD

Fimbrial haemagglutination by Neisseria gonorrhoeae.

The presence of filamentous appendages distinct from flagella was first discovered in electron microscope preparations by Anderson (1949) and Houwink and van Iterson (1950). Duguid, Smith, Dempster, and Edmunds (1955) confirmed the existence of these structures and suggested the name 'fimbriae' for them; others have called them 'cilia' (Pershina and Vasilieva, 1960) and 'pili' (Brinton, 1959). ...

Neisseria gonorrhoeae

Two fi-lactamase-producing strains of Neisseria gonorrhoeae were studied. The substrate profile, molecular weight, and isoelectric point of their ,8-lactamases were similar to those of the TEM-1 enzyme produced by many gram-negative bacilli. The gonococcal f8-lactamase was cell bound during exponential growth and was most likely located in the periplasm. Penicillin hydrolysis was efficient in i...

Neisseria gonorrhoeae

Expression of Type IV pili by the bacteria! pathogen Neisseria gonorrhoeae appears to be essential for colonization of the human host. Several N. gonorrhoeae gene products have been recently identified which bear homology to proteins invoived in pilus assembly and protein export in other bacterial systems. We report here the isolation and characterization of transposon insertion mutants in N. g...
