  1. Estimates of genetic diversity (θ), recombination (r and C), and growth (g) of seven concatenated housekeeping genes, two concatenated fluoroquinolone resistance genes, and the porB gene (PIA and PIB) for the entire Shanghai gonococcal population and partitions by year of isolation. LAMARC's confidence intervals (5% and 95%) around the estimates of each parameter are given between brackets. N S = Number of sequences (isolates).
