In the United States, gonorrhea is the second most commonly reported notifiable disease, with 339,593 cases documented in 2005. Since 1993, fluoroquinolones (i.e., ciprofloxacin, ofloxacin, or levofloxacin) have been used frequently in the treatment of gonorrhea because of their high efficacy, ready availability, and convenience as a single-dose, oral therapy. However, prevalence of fluoroquino...

A lectin slide agglutination test has been developed for the confirmatory identification of Neisseria gonorrhoeae. With wheat germ lectin as an agglutinin, 164 of 165 clinical isolates of N. gonorrhoeae gave a 3 to 4+ reaction within 6 to 8 min. Four gonococcal isolates, even though negative by the fluoresecent-antibody method, gave strong positive reactions with the wheat germ lectin. Among 23...

Beta-lactamase-negative Neisseria gonorrhoeae infections were treated with single-dose cefoperazone (0.5 or 1.0 g) or spectinomycin (2.0 g). Anogenital infections were cured in 36 (83%) of 43 volunteers given 0.5 g of cefoperazone, 61 of 61 volunteers given 1.0 g of cefoperazone, and 99 of 100 volunteers given spectinomycin. The cefoperazone geometric mean MIC for 242 isolates was 0.028 microgr...

Susceptibility of Neisseria gonorrhoeae to gentamicin, the primary treatment for gonorrhea in Malawi since 1993, was determined by using agar dilution MICs, E-test MICs, disc diffusion, and clinical cure rate. Agar dilution MICs were slightly higher in 1996 than in 1993 isolates, with a concomitant drop in the clinical cure rate. E-test MICs were substantially lower than agar dilution determina...

A retrospective case-control study, published online in The Lancet on July 10, 2017, reported that MeNZB–a group B meningococcal vaccine– was effective for preventing gonorrhea acquisition. The vaccine was administered to about 1 million adolescents in New Zealand between 2004 and 2006, and gonorrhea cases fell 31% in those vaccinated compared to unvaccinated controls. The exact mechanisms by w...

The gonococcal porA pseudogene is a popular target for in-house Neisseria gonorrhoeae PCR methods. With this study we present two novel findings: the first case of an N. gonorrhoeae porA pseudogene PCR false-negative result caused by sequence variation, and in the same organism, the first description of a clinical N. gonorrhoeae strain harbouring an N. meningitidis porA sequence.

Ninety-eight per cent of laboratory isolates of Neisseria gonorrhoeae from a veneral disease clinic gave positive reactions with a gonococcal coagglutination test. The prototype reagent, however, was poor at distinguishing between different species of the genus Neisseria: 75% of strains of Neisseria meningitidis and 40% of other Neisseria species tested gave positive reactions. None of the orig...

A hybridoma derived from a mouse immunized with gonococcal outer membranes produced an antibody, designated H.8, that bound to all strains of Neisseria gonorrhoeae and N. meningitidis tested, and to N. lactamica and N. cinerea, but only rarely to other nonpathogenic Neisseria species. Studies with the gonococcal strain used in production of the antibody showed that the antibody bound to a surfa...

OBJECTIVES Recent emergence of the extensively drug-resistant Neisseria gonorrhoeae H041 strain in Japan raises concerns that gonorrhoea may soon become untreatable and emphasizes the need for enhanced surveillance. In this study we developed a real-time PCR assay for direct detection of the H041 strain. METHODS Two real-time PCR assays for detection of the penA gene of the H041 strain, H041-...
