Strain differentiation of Neisseria gonorrhoeae by reverse passive hemagglutination.
A reverse passive hemagglutination test that utilizes human erythrocytes coated with antibody to gonococci was developed to distinguish differences among 11 strains of Neisseria gonorrhoeae. Different rabbits were immunized with each strain of gonococcus. Antibody was purified by passing antiserum over an immunoadsorbent column containing homologous cell walls trapped in a cross-linked polyacry...
متن کاملInterference by Neisseria gonorrhoeae growth by other bacterial species.
Growth of Neisseria gonorrhoeae from clinical specimens has been enhanced by the use of selective media that inhibit the simultaneous growth of other microorganisms. One explanation for this enhancement could be that certain other bacteria inhibit gonococcal growth. This hypothesis was examined by testing 167 bacterial isolates for in vitro gonococcal inhibition; 34.1% of the isolates failed to...
متن کاملBacterial interference of Neisseria gonorrhoeae by alpha-haemolytic streptococci.
Fifty pharyngeal isolates of alpha-haemolytic streptococci were tested against 20 cervical isolates of Neisseria gonorrhoeae for bacterial interference in vitro using the lawn-spotting method. Forty-seven (94%) isolates of streptococci showed inhibitory activity toward N gonorrhoeae, although nine of these were inhibitory to only one isolate of N gonorrhoeae. Isolates of N gonorrhoeae varied wi...
متن کاملFimbrial 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). ...
متن کاملNeisseria 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...
