Gonorrhoea is the term used to describe the clinical manifestations of infection with the bacterium Neisseria gonorrhoeae. Neisseria gonorrhoeae is a Gram-negative diplococcus which usually infects the columnar epithelium of mucous membranes, including the lower male and female genital tracts, the rectum, the pharynx, and the conjunctivae. Transmission is by direct exposure of a mucous membrane to infected secretions, classically via sexual contact. Those who are most at risk of infection include younger age groups (15–29 years), inner-city residents, ethnic minority groups, and men who have sex with men. This chapter discusses the etiology, symptoms, demographics, natural history, complications, demographics, diagnosis, prognosis, and treatment of gonorrhoea.

Introduction: Chlamydia trachomatis and Neisseria gonorrhoeae are the most common causes of sexually transmitted disease in Senegal and worldwide. Molecular techniques have become the standard for their detection, and due to the frequency of co-infections, these tests can detect both agents and can be used on urine samples, vaginal swabs, or endocervical samples. In developing countries, the use of these molecular techniques is very limited and there is a need for evaluations of these techniques to be done. Methodology: A total of 181 samples were tested with the Abbott RealTime CT/NG assay and compared with the Roche Cobas Amplicor CT/NG assay. Specimens were collected from the key population of men having sex with men (urine, n = 60), female sex workers (genital swabs, n = 60) and from women visiting the laboratory for a gynecological checkup (urine, n = 60 and endocervical samples, n = 61). Results: The agreement between the two techniques was 98.90% with a Kappa coefficient of 0.98. A sensitivity of 93.3%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 93.3% were found for both Chlamydia trachomatis and Neisseria gonorrhoeae. Conclusion: These results showed that both methods are similar and suitable for the detection of CT/NG in all types of samples examined in this study.

ABSTRACT Neisseria gonorrhoeae is the bacterium that causes gonorrhea, a major sexually transmitted disease and a significant cofactor for human immunodeficiency virus transmission. The retactile N. gonorrhoeae type IV pilus (Tfp) mediates twitching motility and attachment. Using live-cell microscopy, we reveal for the first time the dynamics of twitching motility by N. gonorrhoeae in its natural environment, human epithelial cells. Bacteria aggregate into microcolonies on the cell surface and induce a massive remodeling of the microvillus architecture. Surprisingly, the microcolonies are motile, and they fuse to form progressively larger structures that undergo rapid reorganization, suggesting that bacteria communicate with each other during infection. As reported, actin plaques form beneath microcolonies. Here, we show that cortical plaques comigrate with motile microcolonies. These activities are dependent on pilT, the Tfp retraction locus. Cultures infected with a pilT mutant have significantly higher numbers of apoptotic cells than cultures infected with the wild-type strain. Inducing pilT expression with isopropyl-β-d-thiogalactopyranoside partially rescues cells from infection-induced apoptosis, demonstrating that Tfp retraction is intrinsically cytoprotective for the host. Tfp-mediated attachment is therefore a continuum of microcolony motility and force stimulation of host cell signaling, leading to a cytoprotective effect.

A clinical, epidemiologic and laboratory study was undertaken in a housing development during an epidemic of illness due to ECHO virus, type 9. The clinical manifestations varied with age. The younger children exhibited an exanthem while older persons frequently had evidence of irritation of the central nervous system. Multiple cases occurred within families, with the incidence of illness highest in the younger age groups. No serious consequences of the illness were seen. Echo 9 virus was recovered with greater frequency from the intestinal contents of young children with illness than from ill adults, although serologic evidence of recent infection in these adults could be demonstrated. The rate of inapparent infection with ECHO 9 virus was low. Virus rarely persisted in the feces beyond 14 days after onset of illness. Group B Coxsackie viruses, type 4 and type 5, were found also to be the cause of many infections within the same population at the same time. Illnesses due to these viruses were similar to those due to ECHO 9 virus, except that no eruption was observed. The rate of inapparent infection was higher than that observed with ECHO 9 virus. Simultaneous infection with ECHO 9 virus and Coxsackie B4 or B5 virus was rare.

Since February 2017 in Poland, an increasing number of acute hepatitis A (AHA) cases have been reported; a noteworthy increase to 3,072 cases of AHA in 2017 compared to 35 cases in 2016 was reported by the National Institute of Public Health (NIPH). The aim of this study was to evaluate the demographic features, clinical manifestations, laboratory results, and sexually transmitted coinfections. All cases of AHA diagnosed between February 2017 and February 2018 at the University Hospital in Krakow were analyzed. A total of 119 cases of hepatitis A virus (HAV) were reported; 105 (88%) were males and 14 (12%) were females, with a mean age 31 years (range 19–62). In 84 patients (71%), the HAV was transmitted by oral–anal sexual contact between men. Six women were infected by close house contact with men infected with HAV. The route of transmission was not identified for 29 cases, and 88 patients (74%) required hospitalization. Among the cases, the following coinfections were already diagnosed: HIV 36 patients (30%), chronic hepatitis C virus (HCV) 4 patients (3%), and chronic hepatitis B virus (HBV) 2 patients (1.5%). During AHA diagnosis, some new sexually transmitted infections (STIs) were detected; syphilis eight patients (6.7%), HIV/syphilis seven patients (6%), HIV//HCV/syphilis one patient, and acute retroviral syndrome/ Shigella flexneri one patient. Overall, AHA outbreak in Poland in 2017 affected primarily men who have sex with men (MSM) and was connected with oral–anal sexual contacts, and the majority of patients did not have HAV vaccination. These results show a clear need for routinely offering HAV vaccination to at-risk populations and that awareness among health-care workers about HAV sexual transmission may help introduce prevention methods.

ABSTRACT Chlamydia trachomatis and Neisseria gonorrhoeae are the two most common causes of sexually transmitted disease in the United States. Studies in adults, mostly in men who have sex with men, have shown that the prevalence of C. trachomatis and N. gonorrhoeae infections is much higher in extragenital sources compared to urogenital sources. A similar large sample of data on the burden of C. trachomatis and N. gonorrhoeae infections by anatomic site is lacking in children. We retrospectively analyzed data from 655 patients tested for C. trachomatis (887 specimens) and N. gonorrhoeae (890 specimens) at the Children’s Hospital of Philadelphia. We restricted the analysis to include patients between 2 and 17 years of age that had all three sources (urine, oropharynx, and rectum) collected at the same visit. The final data set included specimens from all three sources from 148 and 154 patients for C. trachomatis and N. gonorrhoeae, respectively. Specimens were tested for C. trachomatis and N. gonorrhoeae using a Gen-Probe Aptima Combo 2 assay. The burden of C. trachomatis and N. gonorrhoeae infection was significantly higher in the 14- to 17-year age group (24.7%, P = 0.041; 25.8%; P = 0.001) compared to the 10- to 13-year (5.9%; 5.6%), 6- to 9-year (4.6%; 4.6%), and 2- to 5-year (8.3%; 0%) age groups, respectively. The positivity rate for C. trachomatis was highest for rectal (16.2%), followed by urine (5.4%) and oropharyngeal (0.7%) sites. The positivity rate for N. gonorrhoeae was highest for rectal sites (10.4%), followed by oropharyngeal (9.7%) and urine (1.9%) sites. The source with highest diagnostic yield is rectum for C. trachomatis and rectum and oropharynx for N. gonorrhoeae. Hence, extragenital screening is critical for the comprehensive detection of C. trachomatis and N. gonorrhoeae in the pediatric population.
