Since molecular typing can complement contact tracing for reconstructing gonorrhea sexual networks, the concordance between the NG-MAST genotypes of pairs of\n            <jats:italic>N. gonorrhoeae<\/jats:italic>\n            isolates from recent sexual contacts was examined. Among 72 pairs of gonococci from recent sexual contacts, the genotypes of each pair were concordant in 65 cases (90.3%). In two further pairs, the isolates from sexual contacts differed by only a single nonsynonymous substitution in the porin gene, and in both of these pairs, the isolates were the same by\n            <jats:italic>opa<\/jats:italic>\n            typing. The other five nonconcordant pairs of isolates were clearly different strains.\n            <jats:italic>opa<\/jats:italic>\n            typing data were available for 51 of the pairs of isolates from sexual contacts, and concordant\n            <jats:italic>opa<\/jats:italic>\n            types were obtained in 38 cases (74.5%). NG-MAST should therefore be better than\n            <jats:italic>opa<\/jats:italic>\n            typing at identifying recent sexual contacts and has the important advantage over\n            <jats:italic>opa<\/jats:italic>\n            typing of being a more precise method of strain characterization.\n
