Recombinant rOmpL37 expressed by E. coli was used as the antigen in ELISA. Mean values were calculated from serum samples assayed in triplicate. Results are expressed as the mean absorbance ± standard deviation. OD492, optical density at 492 nm. Significant differences, at a P value of 0.001 in comparison to the control group, are shown by an asterisk.
