Аннотация
BACKGROUND: Gonorrhea, when left untreated, can enter the blood and cause disseminated gonococcal infections (DGIs). Disseminated gonococcal infections, which can include dermatitis, tenosynovitis, migratory polyarthralgia, and arthritis, have been increasing in Manitoba (MB), Canada, since 2013. Endocarditis, a rare DGI, was identified in 3 MB patients in 2018 and 2019.
METHODS: Antimicrobial resistance, molecular types, and resistance-associated mutations were determined for MB DGI isolates (n = 103) identified from 2013 to 2020 using phenotypic and genotypic methods. Neisseria gonorrhoeae multiantigen sequence typing (NG-MAST) of residual nucleic acid amplification testing samples (n = 13) from 2019 and 2020 were also determined.
RESULTS: The increase in DGI in MB in 2019 and 2020 was due to the NG-MAST 11508 molecular type with porB -2206, a persistent PorB protein structure type "A" allele. These isolates had low-level resistance to erythromycin and tetracycline.
CONCLUSIONS: Molecular surveillance of gonorrhea and, in particular, gonococcal strains resulting in DGI is imperative to monitor clonal transmission within populations. These data can be used to alert public health of emerging issues and support public health interventions.
