NG-STAR

Resistance-based typing of Neisseria gonorrhoeae

The NG-STAR scheme

The MLST-like NG-STAR typing scheme is based on 7 genes associated with antimicrobial resistance. Like MLST, each allele found for each locus is given a unique numerical identifier, while the type code is based on the unique combination of alleles. The seven genes are: penA, mtrR, porB, ponA, gyrA, parC and 23S rRNA. The central registry for the NG-STAR scheme is maintained by the Public Health Agency for Canada - visit their site for more details.

Implementation

The NG-STAR assignments are generated in Pathogenwatch using our in-house MLST/cgMLST software. For more details, visit the MLST section of the documentation.

Alleles or type codes with an * at the start are novel and not in the current version of the NG-STAR database being usef by Pathogenwatch. These codes are unique and specific to the allele or combination of alleles and can be used reliably within Pathogenwatch across versions.

We would like to thank the Public Health Agency for Canada for allowing the CGPS to download and locally host the NG-STAR scheme for public use.
