Strain-specific virulence-associated antigen of Neisseria gonorrhoeae.
A strain-specific virulence-associated antigen has been found in Neisseria gonorrhoeae strain F-62. Using immunodiffusion in agar gel, it has been shown that the antigen is distinguishable from endotoxin and the virulence-associated toxic protein. It does not appear to be derived from pili. The antigen was not detected in T1 and/or T2 colony type cultures of 10 other isolates. It exhibited a po...
متن کاملRole of pili in the virulence of Neisseria gonorrhoeae.
Gonococci of the colonial types that are associated with virulence, types 1 and 2, have pili that enable the bacteria both to attach in vitro to human epithelial cells and to resist phagocytosis by polymorphonuclear leukocytes. These piliated gonococci also agglutinate various mammalian and chicken erythrocytes. Gonococci of an avirulent colonial type, i.e., type 4, have no pili and neither att...
متن کاملIsolation and characterization of the antigen of Neisseria gonorrhoeae.
The beta antigen of Neisseria gonorrhoeae has been isolated from the alkaline-extracted gonococcal endotoxin by ion exchange, molecular sieve, and powder block electrophoretic chromatography. Hemagglutination inhibition studies indicate that the preparation is essentially free of common enterobacterial and gonococcal alpha antigen. Analysis of the isolated antigen by immunodiffusion and acrylam...
متن کاملCooperative Recognition of Internationally Disseminated Ceftriaxone-Resistant Neisseria gonorrhoeae Strain
Ceftriaxone remains a first-line treatment for patients infected by Neisseria gonorrhoeae in most settings. We investigated the possible spread of a ceftriaxone-resistant FC428 N. gonorrhoeae clone in Japan after recent isolation of similar strains in Denmark (GK124) and Canada (47707). We report 2 instances of the FC428 clone in Australia in heterosexual men traveling from Asia. Our bioinforma...
متن کاملStrain 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...
