  1. A total of 58 N. gonorrhoeae isolates collected in Liverpool between 1981 and 1989 were compared with collections of N. gonorrhoeae, N. lactamica and N. meningitidis.
  2. *This statistic measures the extent of genetic differentiation and computes an average level of gene flow (F ST = 0 free genetic recombination, F ST = 1 recombination unlikely).
