Article Abstract
Infection with Neisseria gonorrhoeae, the causative agent of gonorrhoea, causes significant morbidity worldwide and can have long-term impacts on reproductive health. The greatest global burden of gonorrhoea occurs in low- and middle-income settings. Global public health significance is increasing due to rising antimicrobial resistance (AMR), which threatens future gonorrhoea management. The oropharynx is an important asymptomatic reservoir for gonorrhoea transmission and a high-risk site for development of AMR and treatment failure. Controlled human infection model (CHIM) studies using N. gonorrhoeae may provide a means to accelerate the development of urgently needed therapeutics, vaccines and other biomedical prevention strategies. A gonorrhoea urethritis CHIM has been used since the 1980s with no reported serious adverse events. Here, we describe the rationale for an oropharyngeal gonorrhoea CHIM, including analysis of potential ethical issues that should inform the development of this novel study design.

There is growing evidence that microbial dysbiosis is intimately related to carcinogenesis across several types of human cancer. is best known for causing acute exudative genitourinary infection in males. can also cause chronic, asymptomatic infection of the female genitourinary tract along with the oropharynx and rectum of both sexes.

Department of Public Health, Public Health Service (GGD) Rotterdam-Rijnmond, Rotterdam, Netherlands.
Background: Sexual health centres (SHCs) in the Netherlands report a surge in gonorrhoea, especially among young women (notably oropharyngeal) and men who have sex with women (MSW) since the second half of 2022. MSW are not routinely oropharyngeal tested, and women only when reporting oral sex. This cross-sectional study aimed to assess oropharyngeal gonorrhoea in MSW and women, and potential underdiagnosis.

Background: Antimicrobial resistance (AMR) in Neisseria gonorrhoeae (N. gonorrhoeae) is an urgent global health concern. Commensal Neisseria species in the oropharynx are an important reservoir of AMR genes that are transferred to N.

Background: Despite mounting evidence showing that kissing (tongue-kissing) may transmit gonorrhoea between men who have sex with men (MSM), little data exists on factors influencing the duration of kissing while they are above and/or lying underneath a partner for this population group.
Methods: Between May 2019 and March 2020, we invited MSM aged ≥18 years who attended the Melbourne Sexual Health Centre (MSHC) to participate in a survey about the duration of their kissing (minutes) and intimate position while kissing (i.e.
