Diagram showing the percent distribution of different genetic loci in the English isolates. The presence of the cag PAI with the motifs on its right end, the vacA and iceA genotypes and the presence of the glmM and babB house keeping genes and characteristics of the virulence gene oipA and the genes included in the plasticity region cluster are shown. The distribution was determined by PCR using primer sequences from the reference articles denoted by the number in superscript.
