Fig. 3From: The attachment process and physiological properties of Escherichia coli O157:H7 on quartzqPCR analysis of selected gene expression in quartz-attached and planktonic E. coli O157:H7. The attached cells were compared with the planktonic cells. Data were normalized to gapA expression levels. These genes were grouped by the following functional pathways: flagellar motility and bacterial chemotaxis (a), TCA cycle (b), fermentation metabolism (c), general stress response (d), and antibiotic resistance and pathogenicity (e). The asterisk represents a significant difference between the wild-type and mutant strains (p < 0.05)Back to article page
