Identification of sexual networks through molecular typing of quinolone-resistant Neisseria gonorrhoeae in Ontario, Canada.

Neisseria gonorrhoeae multi-antigen sequence typing technique demonstrated multiple sexual transmission networks in Ontario, Canada. Isolates with novel sequences had higher odds of originating in Toronto but had no association with heightened population-level quinolone exposure. Neisseria gonorrhoeae multi-antigen sequence typing technique can be a useful tool for investigation of multidrug-resistant N. gonorrhoeae emergence in North America.
