Lewis DA. The role of core groups in the emergence and dissemination of antimicrobial resistant N. gonorrhoeae. *Sex Transm Infect* 2013;89:iv47–iv51

The following statement in the concluding paragraph of the section entitled ‘Cephalosporin resistant *N. gonorrhoeae*' contains inaccurate information on the year of isolation of the H041 strain and its NG-MAST sequence type. The text should read as follows:

The first case involved a 31 year-old female sex worker, who was screened for gonorrhoea in Kyoto in early 2009. Her pharyngeal culture grew *N. gonorrhoeae* for which the ceftriaxone minimum inhibitory concentration (MIC) was 2 mg/L. This strain (H041), which was typed as ST4220 by NG-MAST, had a novel *penA* mosaic allele that was closely related to *penA* mosaic allele X responsible for prior cefixime treatment failures in Japan.
