Fig. 5From: Attack of the clones: whole genome-based characterization of two closely related enterohemorrhagic Escherichia coli O26 epidemic lineagesStx2a production in nEC strains. The chart depicts Stx2a amounts, cytotoxicity titers, and specific activities of Stx2a produced by EHEC O26 ST29 late nEC strains harboring different types of stx2a-converting phages (as denoted in Fig. 2), ST29 early nEC strains and ST21 Stx2a-producing strains. The data are means from four measurements. *p < 0.01 for comparisons between the indicated characteristics of ST21 strains and ST29 strains (one-way ANOVA)Back to article page
