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.
