Figure 4

Induction of Stx2 phages by treatment with high concentrations of chlortetracycline (CTC) and oxytetracycline (OTC). The phage titer was determined in Escherichia coli O157:H7 EDL933 by treatment with 1 to 8 µg/mL of CTC and OTC. The results show means and SDs of 3 independent experiments. Statistical significance was analyzed by using the Student t-test in comparison with antibiotic-free cultures. **p<0.01, ***p<0.001, ****p<0.0001.
