Sera obtained from 34 men with Chlamydia trachomatis positive non-gonococcal urethritis, 34 men with C trachomatis negative non-gonococcal urethritis, 42 women with acute salpingitis, 38 healthy women, and 34 healthy men were studied for the presence of specific serum C trachomatis IgA and IgG antibodies. Serological results were correlated with C trachomatis isolation in cell culture. An enzym...

In 37 homosexual men the incidences of urethral, rectal, and pharyngeal gonorrhoea were 45.9%, 56.8%, and 27% respectively. Local symptoms were present in all men with urethral gonorrhoea but in only 25% of those with pharyngeal or rectal gonorrhoea or both. Infection at two sites was found in 29.7% of the patients. Forty-nine gonococcal isolates from the 37 patients were serogrouped by coagglu...

Neisseria gonorrhoeae is an obligate human pathogen that causes gonorrhea. We have shown previously that complement receptor 3 and Akt kinase play important roles in mediating cervical infection. At present, there are limited data to indicate how hormonally induced changes to the mucosal epithelia of the female genital tract mediate the course of gonococcal disease. Hence, I have expanded upon ...

We surveyed the rate of chlamydial and gonococcal infections among human immunodeficiency virus (HIV)-seropositive patients in Thailand as well as the current status of antimicrobial resistance of Neisseria gonorrhoeae and determined the prevalence of penicillinase-producing N. gonorrhoeae (PPNG) in Thailand. A total of 1,158 endocervical swabs from 824 HIV-seropositive patients were collected ...

In a study of 157 men and 141 women with gonorrhoea post-gonococcal urethritis (PGU) in men was significantly more common among chlamydia-positive (76%) than among chlamydia-negative (22.5%) patients. Clinical investigations of PGU detected 95% of the patients infected with C trachomatis. PGU was, however, asymptomatic in over half of the patients and a careful follow-up for 3-6 weeks was neces...

Some human sera contain factors which induce in gonococci a resistance to killing by fresh human sera. Individuals with serum containing these factors might possibly be more prone to gonorrhoea. A survey of the sera of 50 female and 50 male patients with gonorrhoea for resistance-inducing capacity showed, however, that the proportions of positive sera (24% for women, 28% for men) were not signi...

Complement forms a key arm of innate immune defenses against gonococcal infection. Sialylation of gonococcal lipo-oligosaccharide, or expression of porin 1A (Por1A) protein, enables Neisseria gonorrhoeae to bind the alternative pathway complement inhibitor, factor H (fH), and evade killing by human complement. Using recombinant fH fragment-murine Fc fusion proteins, we localized two N. gonorrho...

Paired sera from 60 consecutive patients with acute salpingitis, confirmed by laparoscopy, were examined for serum antibodies to Chlamydia trachomatis, Mycoplasma hominis, and Neisseria gonorrhoeae. By a microimmunofluorescence (MIF) test IgM or IgG antibodies to C trachomatis or both were present in sera from 80% of the patients' by indirect haemagglutination (IHA) tests antibodies to M homini...

Demographic data The study was undertaken at Whittall Street STI clinic, Birmingham. Of the 334 cases of gonococcal infection, 216 (64.7%) were male. Ages ranged from 14 to 58 years. Ethnicity data revealed that 179 (53.6%) cases were Afro-Caribbean, 64 (19.2%) were white, 25 (7.5%) were other specified groups, there was no information regarding the ethnic origin of the remaining 66 (19.8%).
