Abstract
BACKGROUND Antimicrobial resistance (AMR) of untreatable gonococcal infection is an emerging threat, especially in Guangdong, a prosperous province in Southern China. METHODS N.gonorrhoeae was isolated from 20 cities in Guangdong and determined antimicrobial susceptibility. Through whole-genome sequencing (WGS), multilocus sequence typing (MLST), N.gonorrhoeae multiantigen sequence typing (NG-MAST), and N.gonorrhoeae sequence typing for antimicrobial resistance (NG-STAR) were obtained based on the PubMLST database ( https://pubmlst.org/ ). Phylogenetic analysis was used for dissemination and tracking analysis. RESULTS Antimicrobial susceptibility was performed on 347 isolates, and 50 isolates were identified as decreased susceptibility (DS) to cephalosporins. Of which 16.0% (8/50) were ceftriaxone DS, 38.0% (19/50) were cefixime DS, and 46.0% (23/50) were both ceftriaxone and cefixime DS. In all, the dual-resistant rate of the cephalosporin-DS isolates was 96.0% for penicillin and 98.0% for tetracycline-resistant, and 10.0% (5/50) were resistant to azithromycin. All cephalosporin-DS isolates were resistant to ciprofloxacin but sensitive to spectinomycin. The predominant MLSTs were ST7363 (16%, 8/50), ST1903 (14%, 7/50), ST1901 (12%, 6/50), and ST7365 (10%, 5/50). Besides some isolates that failed genotyping (NA), NG-STAR ST1143 (n = 6) and NG-MAST ST17748 (n = 4) were the most prevalent. Twelve isolates with mosaic penA-60.001 allele retained the most elevated cephalosporin MIC (Minimum Inhibitory Concentration). Phylogenetic analysis revealed that epidemic penA-60.001 clones, either domestic or foreign, had spread to nine cities in Guangdong, and 9/12 clones were from the Pearl River Delta region. CONCLUSIONS N. gonorrhoeae with cephalosporins-DS was extensively disseminated in Guangdong, Southern China, requiring strict surveillance.

Emerg Microbes Infect 2022; 11:344-350.

Abstract
Background: After Neisseria gonorrhoeae FC428 was first found in Japan, ceftriaxone-resistant strains disseminated globally, and the gonococcal resistance rate increased remarkably. Epidemiological investigations are greatly significant for the analysis of antimicrobial resistance (AMR) trends, molecular features and evolution. Objectives: To clarify the AMR trend from 2016–2019 and reveal the molecular characteristics and evolution of ceftriaxone-resistant penA 60.001 isolates. Methods: The minimum inhibitory concentrations (MICs) of antibiotics against 4113 isolates were detected by the agar dilution method. N. gonorrhoeae multiantigen sequence typing (NG-MAST), multilocus sequence typing (MLST) and N.gonorrhoeae sequence typing for antimicrobial resistance (NG-STAR) were used to identify the sequence types. Genome analysis was conducted to analyze resistance genes, virulence factors, and evolutionary sources. Results: Isolates with decreased ceftriaxone susceptibility have increased from 2.05% (2016) to 16.18% (2019). Six ceftriaxone-resistant isolates possessing penA 60.001 appeared in Guangdong Province, and were resistant to ceftriaxone, penicillin, tetracycline, ciprofloxacin and cefixime, but susceptible to azithromycin and spectinomycin. Single-nucleotide polymorphisms (SNPs) in the porB gene were the major cause of different NG-MAST types. ST1903 was the main NG-STAR genotype and only strain-ZH545 was ST7365, with molecular features consistent with the MICs. Furthermore, different MLSTs suggested diverse evolutionary sources. Genome analysis revealed a set of virulence factors along with the resistance genes “penA” and “blaTEM-1B”. Half of penA 60.001 strains were fully mixed with global FC428-related strains. Conclusions: Global FC428-related clones have disseminated across Guangdong, possibly causing decreased ceftriaxone susceptibility. Enhanced gonococcal surveillance will help elucidate the trajectory of transmission and curb further dissemination.

[PMID: 32473014 DOI: 10.1093/jac/dkaa196] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Revised: 03/25/2020] [Accepted: 04/18/2020] [Indexed: 01/25/2023] Open
Abstract
BACKGROUND Ceftriaxone resistance in Neisseria gonorrhoeae has become an imminent threat to effective control of gonorrhoea globally. In recent years, the ceftriaxone-resistant FC428 clone has shown international dissemination. After our first report of the FC428 clone in China in 2016, we now describe another six cases of FC428-related ceftriaxone-resistant N. gonorrhoeae isolates from 2017 and 2018. OBJECTIVES To identify the phenotypic and molecular characteristics of newly reported ceftriaxone-resistant isolates in China and to investigate the relationship between these isolates and FC428 clones reported globally. METHODS Antimicrobial susceptibility to ceftriaxone, cefixime, azithromycin, spectinomycin, penicillin, ciprofloxacin and tetracycline was determined by the agar dilution method. N. gonorrhoeae multi-antigen sequence typing (NG-MAST), MLST and N. gonorrhoeae sequence typing for antimicrobial resistance (NG-STAR) were performed for genotyping and SNPs extracted from whole-genome sequences were used for phylogenetic analysis. RESULTS All isolates were resistant to ceftriaxone, cefixime, penicillin, tetracycline and ciprofloxacin, but were susceptible to azithromycin and spectinomycin. NG-MAST, MLST and NG-STAR genotyping showed that all isolates shared identical or similar STs (<10 bp difference) to FC428 (NG-MAST ST3435, MLST ST1903, NG-STAR ST233) and contained the same mosaic penA allele 60.001. Phylogenetic analysis showed the Chinese isolates spreading in the whole phylogenetic tree and fully mixed with other international isolates. Half of the Chinese isolates were more closely related (<100 SNPs) to Japanese isolates than other international isolates. CONCLUSIONS The newly reported cases in China were related to the internationally spreading FC428 clone. These isolates might have played a central role in international transmission of the FC428 clone. High ceftriaxone doses (1-2 g) still provide effective therapy.

Abstract
Gonococcal antimicrobial resistance (AMR) has become a global threat significantly hampering the control of gonorrhea. Many socioeconomic, biological, behavioral, and programmatic factors have played an important role in driving the emergence, transmission and spread of gonococcal AMR. However, research to address these scientific and programmatic questions is limited in China. Here we propose a ROADMAP (acronym for resistance surveillance, outcomes due to AMR, antibiotic stewardship and application, diagnostic tools, mechanisms of AMR, antimicrobial assessment, and population pharmacokinetics and pharmacodynamics) plan for expanding interdisciplinary collaborations to address the research needs in China.
