Protection efficacy after immunization with rOmpF against E. coli CVCC 1515 and CICC 21530 (O157:H7) in vivo. After 2 weeks of the final immunization, the mice were challenged with E. coli CVCC 1515 by intraperitoneal injection (A) or E. coli CICC 21530 (O157:H7) by gastric tube (B), and observed for 7 days after challenge. Data are expressed as mean ± SD. A The survival ratio of the mice immunized with rOmpF or PBS; rOmpF+ adjuvant: group 1; PBS+ adjuvant: group 2, control; B fecal shedding of the mice immunized with rOmpF or PBS; rOmpF+ adjuvant: group 3; PBS+ adjuvant: group 4, control. Asterisk indicates a significant difference between two groups (p < 0.05)
