Claims
- 1. A Gram-negative bacterial bleb not derived from Chlamydia presenting on its surface the PorB outer membrane protein from Chlamydia trachomatis, wherein the combination of the Chlamydia antigen with the native Gram-negative bacterial bleb antigens interact in the prevention or treatment of salpingitis when present in a vaccine formulation.

- 3. The Gram-negative bleb of claim 1 further presenting on its surface MOMP from one or more serovars from Chlamydia trachomatis.
- 4. A Gram-negative bleb not derived from Chlamydia, presenting on its surface both the PmpG and MOMP (from one or more serovars) outer membrane proteins from Chlamydia trachomatis, wherein the combination of the Chlamydia antigens with the native Gram-negative bacterial bleb antigens interact in the prevention or treatment of salpingitis when present in a vaccine formulation.
- 5. The bleb of claims 1-4 which are gonococcal blebs.

- 7. The bleb of claims 5 and 6 derived from a gonococcal strain which has been modified to downregulate one or more immunodominant variable or non-protective gonococcal outer membrane antigens.
- 8. The bleb of claims 5-7 derived from a strain which has a detoxified lipid A portion of bacterial LPS, due to the strain having been engineered to reduce or switch off expression of one or more genes selected from the group consisting of: htrB, msbB and lpxK.
- 9. The bleb of claims 5-8 wherein the bleb preparation is derived from a strain which has a detoxified lipid A portion of bacterial LPS, due to the strain having been engineered to express at a higher level one or more genes selected from the group consisting of: pmrA, pmrB, pmrE and pmrF.
- 10. A vaccine composition comprising the bleb of claims 1-9 and a pharmaceutically suitable excipient or carrier.
- 11. The vaccine of claim 10, additionally comprising a mucosal adjuvant.
- 12. A method of preventing Chlamydia trachomatis infection in a host comprising the steps of administering an effective amount of the vaccine of claim 10 or 11 to a host in need thereof.
- 13. The method of claim 12 where in the vaccine is mucosally administered via either a intranasal, oral, or intravaginal route.
- 14. A Gram-negative bleb produced from Neisseria meningitidis, Moraxella catharralis or Haemophilus influenzae presenting on its surface a protective antigen from Chlamydia pneumoniae.
- 15. The Gram-negative bleb of claim 14 presenting on its surface a PorB outer membrane protein from Chlamydia pneumoniae.
- 16. The Gram-negative bleb of claim 15 further_presenting on its surface MOMP outer membrane protein from Chlamydia pneumoniae.
- 17. The Gram-negative bleb of claim 15 further_presenting on its surface one or more Pmp outer membrane proteins from Chlamydia pneumoniae.
- 18. The Gram-negative bleb of claim 15 further_presenting on its surface Npt1 protein from Chlamydia pneumoniae.
- 19. The Gram-negative bleb of claim 14 presenting on its surface one or more Pmp proteins from Chlamydia pneumoniae.
- 20. The Gram-negative bleb of claim 19 further_presenting on its surface Npt1 protein from Chlamydia pneumoniae.
- 21. The Gram-negative bleb of claim 19 further presenting on its surface MOMP protein from Chlamydia pneumoniae.
- 22. The Gram-negative bleb of claim 14 presenting on its surface MOMP protein from Chlamydia pneumoniae.
- 23. The Gram-negative bleb of claim 22 further presenting on its surface Npt1 protein from Chlamydia pneumoniae.
- 24. The bleb of claims 14-23 which are meningococcal blebs.
- 25. The bleb of claim 24 derived from a meningococcal strain that has been modified to upregulate one or more protective meningococcal outer membrane antigens.
- 26. The bleb of claim 24 or 25 derived from a meningococcal strain that has been modified to downregulate one or more immunodominant variable or non-protective meningococcal outer membrane antigens.
- 27. The bleb of claims 24-26 derived from a strain which has a detoxified lipid A portion of bacterial LPS, due to the strain having been engineered to reduce or switch oft expression of one or more genes selected from the group consisting of: htrB, msbB and lpxK.
- 28. The bleb of claims 24-27 wherein the bleb preparation is derived from a strain which has a detoxified lipid A portion of bacterial LPS, due to the strain having been engineered to express at a higher level one or more genes selected from the group consisting of: pmrA, pmrB, pmrE and pmrF.
- 29. A vaccine composition comprising the bleb of claims 14-28 and a pharmaceutically suitable excipient or carrier.
- 30. The vaccine of claim 29, additionally comprising a mucosal adjuvant.
- 31. A method of preventing Chlamydia pneumoniae infection in a host comprising the steps of administering an effective amount of the vaccine of claim 29 or 30 to a host in need thereof.
- 32. The method of claim 31 where in the vaccine is mucosally administered via either an intranasal, or oral route.
