Serovar specific immunity to Neisseria gonorrhoeae: does it exist?
OBJECTIVE To determine whether the host immune response to gonorrhoea provides limited serovar specific protection from reinfection. SUBJECTS 508 episodes of gonorrhoea diagnosed at a city centre genitourinary medicine clinic including 22 patients with multiple infections over a 4 year period. METHODS Patients with recurrent gonococcal infection were analysed with respect to the initial and...

متن کاملMucosal Immunity and Evasion Strategies of Neisseria gonorrhoeae
Neisseria gonorrhoeae, the gonococcus, is a gram-negative diplococcus which causes the sexually transmitted disease gonorrhea (Figure 1). The contagious nature of gonococcal infection remains a major global health problem and represents 88 million new cases every year (WHO, 2011). N. gonorrhoeae is transmitted by human to human contact and is highly adapted to the genital tract, surviving poorl...
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...
متن کاملNeisseria 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...
