Table 3 Genetic divergence and gene flow between groups

From: Species status of Neisseria gonorrhoeae: evolutionary and epidemiological inferences from multilocus sequence typing

  Fixed differences Shared polymorphisms (total no. of polymorphisms) Percentage mean nucleotide sequence divergence F ST *
38 N. gonorrhoeae (Liverpool, 2000–2001) 0 15 (23) 0.14 0.01 (p > 0.05)
53 N. gonorrhoeae (collected worldwide) 0 15 (25) 0.15 0.02 (p > 0.05)
103 N. lactamica (Oxfordshire) 170 4 (530) 9.46 0.79 (p < 0.05)
217 N. meningitidis (Czech carriage) 64 3 (570) 6.91 0.61 (p < 0.05)
  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).
