Recombinant OprI protein was used to immunize mice, and was found to be protective against a challenge with a four- to fivefold 50% lethal dose of P. aeruginosa (Finke et al., 1990). Our data showed that mice immunized with OprF/OprI are significantly protected from infection caused by mucoid and nonmucoid strains of P. aeruginosa.(Hassan et al., 2018)
