  • a A chi-square test shows that the distribution of disease and carriage strains between clonal complexes is not significantly different from random (χ2 = 8.4, P = 0.24).

  • b ST145 and ST10 are placed in the singleton category, despite the fact that these clones are closely related, because each is represented by only a single isolate.
