Patent ID: 8637040

Claim:
An isolated immunogenic peptide of at least about 10 amino acids and not longer than about 30 amino acids, which peptide mimics immunologically the structure of chlamydia genus-specific glycolipid exoantigen (GLXA) and binds to an anti-GLXA antibody, and/or when the peptide is administered to a mammalian subject in an adequate amount and in immunogenic form, it induces a protective antibody response that is measurable in: an immunoassay that measures binding to chlamydia organisms of multiple chlamydial species; and/or an immunoassay or biological assay that measures inhibition of function growth or survival of said Chlamydia organisms, wherein the peptide comprises: (a) Pep1, SEQ ID NO:1; (b) Pep2, SEQ ID NO:2; (c) Pep4, SEQ ID NO:4; (d) Pep5, SEQ ID NO:5; (e) Pep6, SEQ ID NO:6; (f) Pep7, SEQ ID NO:7; (g) Pep8, SEQ ID NO:8; (h) Pep9, SEQ ID NO:9; (i) Pep10, SEQ ID NO:10; (j) Pep14, SEQ ID NO:14.
