UNLABELLED Phosphoethanolamine (PEA) on Neisseria gonorrhoeae lipid A influences gonococcal inflammatory signaling and susceptibility to innate host defenses in in vitro models. Here, we evaluated the role of PEA-decorated gonococcal lipid A in competitive infections in female mice and in male volunteers. We inoculated mice and men with mixtures of wild-type N. gonorrhoeae and an isogenic mutan...

Neisseria gonorrhoeae, the causative agent of the sexually transmitted infection (STI) gonorrhea, is a growing public health threat for which a vaccine is urgently needed. We characterized the functional role of the gonococcal MetQ protein, which is the methionine binding component of an ABC transporter system, and assessed its potential as a candidate antigen for inclusion in a gonococcal vacc...

mediciNe & HeAltH/RHode islANd Chlamydia traChomatis (Ct) And Neisseria gonorrhoeae (NG) are the two most common reportable sexually transmitted infections (STIs) in the United States. Adolescent girls (15 to19 years of age) and young women (20 to 24 years of age) are at highest risk for these infections. This likely reflects a combination of factors, including biological differences that place...

BACKGROUND Sex workers in Uganda are at significant risk for HIV infection. We characterized the HIV epidemic among Kampala female sex workers (FSW). METHODS We used respondent-driven sampling to sample FSW aged 15+ years who reported having sold sex to men in the preceding 30 days; collected data through audio-computer assisted self-interviews, and tested blood, vaginal and rectal swabs for ...

Co-infection with two different pathogens may alter the classical clinical course that manifests infection as single pathogen. In STIs, such co-infection may trigger the reactivation of a latent infection, and syndromic approach may not be insufficient to free the host of the entire gamut of infectivity agents. Present study analyzed appropriate samples for Neisseria gonorrheae and HSV from 200...

To evaluate whether bacterial vaginosis predicts the acquisition of sexually transmitted diseases (STDs), we studied 255 nonpregnant female subjects aged 15-30 who reported recent sexual contact with a male partner in whom either gonococcal or chlamydial urethritis or nongonococcal urethritis was diagnosed. Compared to subjects with normal vaginal flora, subjects with bacterial vaginosis were m...

To determine the prevalence and pattern of sexually transmitted diseases among sexually abused children, we evaluated 532 victims under 14 years of age for the presence of Neisseria gonorrhoeae and Treponema pallidum. Twenty-five girls with vaginal discharge and six children with perineal skin lesions underwent more detailed microbiologic examination. Thirty-four infections were identified in 3...

Gonorrhea is a major, global public health problem for which there is no vaccine. The continuing emergence of antibiotic-resistant strains raises concerns that untreatable Neisseria gonorrhoeae may become widespread in the near future. Consequently, there is an urgent need for increased efforts towards the development of new anti-gonococcal therapeutics and vaccines, as well as suitable models ...

A cross sectional descriptive study was conducted from February 2008 to December 2009 at the largest Highway Terminal, Yangon, Myanmar to determine the prevalence of curable STIs (syphilis, gonorrhea, chlamydial infections, and trichomoniasis), to find out the associated factors for STIs, and to determine the antibiotic susceptibility pattern of gonococcal infection among highway drivers. Urine...

BACKGROUND Women who work commercially in sex work (female sex workers [FSW]) are considered a high-risk group for sexually transmissible infections (STI), yet the level of reported pathogens varies in studies around the world. This study reviewed STI rates reported in 42 studies of FSW around the world published between 1995 and 2006 and analysed the trends and types of populations surveyed, e...
