Abstract: A C-terminal pilin peptide vaccine for immunizing or treating a patient for infection by a Pseudomonas aeruginosa (PA) infection is disclosed. The peptide comprises the peptide identified as SEQ ID NOS. 3-6; and a carrier protein conjugated to the peptide. Also disclosed is a pilin peptide C-terminal PA pilin peptide having the amino acid sequence identified as SEQ ID NO: 3, and analogs thereof having one of residues T, K, or A at position 130, D, T, or N at position 132, Q, A, or V at position 133, E, P, N, or A at position 135, Q, M, or K at position 136, and I, T, L, or R at position 138, excluding SEQ ID NOS: 1, 2, 9, 10, and 11, and the ability to cross-react with antibodies against the corresponding C-terminal peptides from PA strains PAK and PAO.
