We compared enzyme immunoassay (Gonozyme; Abbott Laboratories, North Chicago, Ill.) for detection of gonococcal antigen in urine sediments with urethral swab culture for diagnosis of gonorrhea in men attending a venereal disease clinic. The prevalence of infection was 14% by culture (27/196). The sensitivity of enzyme immunoassay was 93% (25/27) compared with the culture method, and the specifi...

BACKGROUND Screening and active case finding for Chlamydia trachomatis (CT) is recommended to prevent reproductive morbidity. However insight in community prevalence of gonococcal infections and co-infections with Neisseria gonorrhoea (NG) is lacking. METHODS Nested study within a large population-based Chlamydia Screening Pilot among 21.000 persons 15-29 year. All CT-positive (166) and a ran...

Natural infection with Neisseria gonorrhoeae may elicit a substantial antibody response directed against gonococcal lipooligosaccharide. Monoclonal antibody (MAb) 2C7 recognized a gonococcal lipooligosaccharide epitope, identified the epitope directly in 94% of 68 consecutive culture-positive genital secretions, and recognized 95% of 101 randomly chosen fresh (second-passage) gonococcal isolate...

To compare the effect of gonococcal co-infection on immortalized versus primary CD4(+) T cells the Jurkat cell line or freshly isolated human CD4(+) T cells were infected with the HIV-1 X4 strain NL4-3. These cells were exposed to whole gonococci, supernatants from gonococcal-infected PBMCs, or N. gonorrhoeae-induced cytokines at varying levels. Supernatants from gonococcal-infected PBMCs stimu...

HIV synergy with sexually transmitted co-infections is well-documented in the clinic. Co-infection with Neisseria gonorrhoeae in particular, increases genital HIV shedding and mucosal transmission. However, no animal model of co-infection currently exists to directly explore this relationship or to bridge the gap in understanding between clinical and in vitro studies of this interaction. This s...

From 1994 to 1997, the proportion of Neisseria gonorrhoeae highly resistant to ciprofloxacin (MIC >/=4 microg/mL) increased substantially among female sex workers (FSWs) in the Philippines. Among 1499 Filipina FSWs, we evaluated factors associated with gonococcal infection and with gonococcal antimicrobial resistance. By multivariate analysis, gonococcal infection was associated with sex with a...

A case of C2 deficiency presenting with disseminated gonococcal infection is described. The predisposition of C2-deficient individuals to infection in addition to the commoner problem of immune complex diseases is noted. Attention is drawn to the absence of documented cases of gonococcal infection associated with C2 deficiency. No other homozygous C2 deficient family members were identified. Li...

CONTEXT The prevalence and distribution of gonococcal and chlamydial infections in the general population are poorly understood. Development of nucleic acid amplification tests, such as the ligase chain reaction assay, provides new opportunities to estimate the prevalence of untreated infections in the population. OBJECTIVE To estimate the overall prevalence of untreated gonococcal and chlamy...

Gonococcal infections other than urethritis have been rare since the advent of antibiotics (Burckhardt, 1955; Gisslen, Hellgren, and Starck, 1961), but interest has recently been shown in the existence of extraurethral gonococcal infections (Bjornberg and Gisslen, 1965; Fred, Eiband, Martincheck, and Yow, 1965; O'Sullivan, 1964; Cowan, 1969). In this paper we present a case of acute penile ulce...

Household epidemics of gonorrhoea are relatively rare in the United Kingdom. We report a cluster of cases of gonococcal infection in four children living in one household. The cases show the importance of full screening, including pharyngeal cultures, of all family members when paediatric gonorrhoea is diagnosed. Our cases also suggest that both boys and girls should be screened for gonorrhoea ...
