Hybridization of the highly variable O-antigen gene cluster by Y. pseudotuberculosis strains. Strain names are followed by their serotype in parentheses. The presence of a gene is indicated by a plus sign (+), absence by a minus sign (-), and divergence by the signal to control ratio represented numerically.
