We examined 12 pairs of strains of Escherichia coli and Klebsiella pneumoniae isolated from mixed infections in human for the presence of the Yersinia high-pathogenicity island (HPI). In one case both isolates carried the HPI, whereas in 11 cases one strain of the pair was HPI-positive. Although there were differences in the organization of the Yersinia HPI, all HPI-positive isolates were able to produce yersiniabactin. The presence of the Yersinia HPI may enhance the capability of strains involved in mixed infections to replicate in iron-deprived conditions in the host.
