Evaluation of Neisseria gonorrhoeae multiple-locus variable-number tandem-repeat analysis, N. gonorrhoeae Multiantigen sequence typing, and full-length porB gene sequence analysis for molecular epidemiological typing

The performance characteristics of Neisseria gonorrhoeae multilocus variable-number tandem-repeat analysis were evaluated, by comparison with N. gonorrhoeae multiantigen sequence typing and full-length porB sequence typing. Assessment of the relatedness of intra- and interpatient isolates showed that all three genotyping techniques display a high resolution and typeability.
