[i] Selected genes that may be involved in virulence or host adaptation. Y. pseudotuberculosis 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.
