Iron-regulated outer membrane proteins (OMPs) of Pasteurella multocida have been shown previously to elicit superior protective immunity. We have identified that high molecular weight OMP 116 kDa was expressed when Pasteurella multocida type 6:B was grown under iron-restricted condition. The highly purified 116 kDa protein was found to be only 60% protective to mice against experimental pasteurellosis. Two other proteins with high molecular weight (MW) (87 and 71 kDa) were shown to be expressed slightly more when grown under iron-restricted condition; however, the protection afforded by 87 kDa protein was is only 40%..
