Serum responses in mice immunized with rOmpF. Mice were immunized with rOmpF at day 0 and boosted at the 3rd-week and 5th-week respectively, and sera were collected at 5-day intervals after each immunization. iELISA was used to detect the antibody titers. Results were shown as mean ± SD for 10 mice. A Titers of the anti-rOmpF sera against rOmpF. Asterisk indicates a significant difference between the OmpF immunized group and the control group (p < 0.05). Different lower case letters indicate a significant difference between each immunized (p < 0.05); B cross-reaction properties of the anti-rOmpF sera against E. coli, Shigella, Salmonella and Pseudomonas. Y axis indicates the optical density (OD 450) values of antibody response with different bacteria in iELISA
