ABSTRACT U.S. gonorrhea rates are rising, and antibiotic-resistant Neisseria gonorrhoeae (AR-Ng) is an urgent public health threat. Since implementation of nucleic acid amplification tests for N. gonorrhoeae identification, the capacity for culturing N. gonorrhoeae in the United States has declined, along with the ability to perform culture-based antimicrobial susceptibility testing (AST). Yet AST is critical for detecting and monitoring AR-Ng. In 2016, the CDC established the Antibiotic Resistance Laboratory Network (AR Lab Network) to shore up the national capacity for detecting several resistance threats including N. gonorrhoeae. AR-Ng testing, a subactivity of the CDC’s AR Lab Network, is performed in a tiered network of approximately 35 local laboratories, four regional laboratories (state public health laboratories in Maryland, Tennessee, Texas, and Washington), and the CDC’s national reference laboratory. Local laboratories receive specimens from approximately 60 clinics associated with the Gonococcal Isolate Surveillance Project (GISP), enhanced GISP (eGISP), and the program Strengthening the U.S. Response to Resistant Gonorrhea (SURRG). They isolate and ship up to 20,000 isolates to regional laboratories for culture-based agar dilution AST with seven antibiotics and for whole-genome sequencing of up to 5,000 isolates. The CDC further examines concerning isolates and monitors genetic AR markers. During 2017 and 2018, the network tested 8,214 and 8,628 N. gonorrhoeae isolates, respectively, and the CDC received 531 and 646 concerning isolates and 605 and 3,159 sequences, respectively. In summary, the AR Lab Network supported the laboratory capacity for N. gonorrhoeae AST and associated genetic marker detection, expanding preexisting notification and analysis systems for resistance detection. Continued, robust AST and genomic capacity can help inform national public health monitoring and intervention.

Azithromycin Resistance

The Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP) in England and Wales has monitored azithromycin resistance since 2001. In 2007, high-level azithromycin resistance (MICs >256 mg/L) was identified for the first time in six isolates, all of which were the same sequence type (ST 649).

SUMMARYThis study compared the antimicrobial susceptibility and genotypes of strains of Neisseria gonorrhoeae isolated from men who have sex with men (MSM) and from heterosexuals. One hundred and eleven strains were characterized from 107 patients, comprising 57 strains from 54 heterosexuals and 54 strains from 53 MSM. Antimicrobial resistance rates were higher in strains from heterosexual patients, with resistance to cefixime (P = 0·0159) and ciprofloxacin (P = 0·002) being significantly higher. Typing by N. gonorrhoeae multi-antigen sequence typing (NG-MAST) showed that the most prevalent sequence types (ST) and genogroups (G) respectively were ST2400, ST2992, and ST5793, and G1407, G2992, and G2400. A statistically significant association was observed for MSM and genogroups G2400 (P = 0·0005) and G2992 (P = 0·0488), and G1407 with heterosexuals (P = 0·0002). We conclude that in our region distinct populations of gonococci are circulating among subjects with different sexual practices, with their corresponding transmission patterns. Furthermore, the high prevalence of genotype G2400 in MSM, has not to our knowledge been previously described.
