The changing epidemiology of Neisseria gonorrhoeae genogroups and antimicrobial resistance in Queensland, Australia, 2010-15: a case series analysis of unique Neisseria gonorrhoeae isolates.

Abstract
BACKGROUND Neisseria gonorrhoeae (NG) can lead to serious reproductive and sexual health outcomes, and the annual number of NG notifications in Australia increased steadily from 10329 in 2010 to 29549 by 2020. Australian populations most affected are urban men who have sex with men and First Nations peoples living in remote areas, and a resurgence in urban heterosexuals has been observed since 2012. METHODS A case series analysis of Queensland NG isolates (2010-15) exploring temporal trends and antimicrobial resistance by demographic and geographic distribution and genotype was performed. Proportions describe age, sex, strain, genogroup (NG multi-antigen sequence typing), region, swab site, antimicrobial sensitivity and isolate rates per 100000 population. Dominant genogroups were identified. RESULTS Among 3953 isolates, the median age was 25years (IQR 20-34years) and most (n =2871/3915, 73%) were men. Brisbane city (68.8) and Far North Queensland (54.1) excluding Cairns showed the highest rates. Forty-six genogroups were documented, seven (G2992, G6876, G1415, G4186, G5, G1407 and G6937) comprised half of all isolates. The predominant male genogroup was G2992 (16%), and G6876 (20%) for females; G5 was predominantly male from 2010 to 2011, but equal in both sexes from 2012 to 2015. CONCLUSION Considerable temporal, geographical and demographical diversity was observed in Queensland NG isolates, which has public health implications. Certain genogroups are more transient than others, and evidence suggests bridging from male-dominant networks to heterosexual networks. Molecular surveillance can enhance tracking the epidemiology and movement of NG in Australia, highlighting the necessity of genotyping to expose potentially prevalent strains circulating in undetected or underrepresented networks by current screening methods.

Selb R, Buder S, Dudareva S, Tamminga T, Bremer V, Banhart S, Heuer D, Jansen K. Markedly decreasing azithromycin susceptibility of Neisseria gonorrhoeae, Germany, 2014 to 2021. Euro Surveill 2021; 26:2100616. [PMID: 34355690 PMCID: PMC8343548 DOI: 10.2807/1560-7917.es.2021.26.31.2100616] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Accepted: 08/03/2021] [Indexed: 11/29/2022] Open
Abstract
We monitored antimicrobial susceptibility developments of Neisseria gonorrhoeae in Germany from January 2014 to May 2021. The proportion of isolates with azithromycin minimum inhibitory concentrations above the epidemiological cut-off increased substantially, from 1.3% in 2014 to 12.2% in 2020. Preliminary data from 2021 showed a further rise (January to May: 20.7%). Therefore, azithromycin as part of the recommended dual therapy in Germany for non-adherent patients is challenged. Antimicrobial susceptibility testing in clinical practice is crucial and continuous susceptibility surveillance indispensable.
