| Abstract: | The present invention relates to methods for the control of virulence of infectious bacteria by modulating the extra-cellular concentration of bacterial cell signalling molecules. Derivatives of cell signalling molecules are conjugated to suitable carrier proteins and used to isolate high affinity receptors recognizing the native signal molecule(s). By binding to signalling molecules, the receptors reduce and maintain extra-cellular concentrations of signal molecules below the threshold level that would otherwise result in certain opportunistic pathogens adopting a virulent form, and can transform virulent organisms to non-virulent states. These receptors have applications for the treatment of individuals with susceptibility to infection, the treatment of patients with existing infections, in disease monitoring and management, and in related applications where the host for infection is an animal or plant. |

| Claim: | 1. A method of screening a naive human phage display library for an anti-bacterial monoclonal antibody, comprising: conjugating a bacterial lactone or lactone-derived signal molecule to a first carrier molecule to generate an enriched library; and screening said enriched library against the bacterial lactone or lactone-derived signal molecule conjugated to a second, different, carrier molecule to identify a monoclonal antibody that specifically binds to the free soluble form of the bacterial lactone or lactone-derived signal molecule from the enriched library in the presence of conjugated derivatives thereof. |
| Claim: | 2. A method as claimed in claim 1 in which the lactone signal molecule is a homoserine molecule or a peptide thiolactone molecule. |
| Claim: | 3. A method as claimed in claim 2 in which the homoserine lactone molecule has a general formula selected from the group consisting of: [chemical expression included] where n =0 to 12. |
| Claim: | 4. A method as claimed in claim 3 in which the homoserine lactone molecule of general formula I is N-butanoly-L-homoserine lactone (BHL) where n =0, N-dodecanoyl-L-homoserine lactone (dDHL) where n =8, or n-tetradecanoyl-L-homoserine lactone (tDHL) where n =10. |
| Claim: | 5. A method as claimed in claim 3 in which the homoserine lactone molecule of general formula II is N-(-3-oxohexanoyl)-L-homoserine lactone (OHHL) where n =2 or N-(-3-oxododecanoyl)-L-homoserine lactone (OdDHL) where n = 8 . |
| Claim: | 6. A method as claimed in claim 3 in which the homoserine lactone molecule of general formula III is N-(- 3 -hydroxybutanoyl)-L-homoserine lactone (HBHL) where n =0. |
| Claim: | 7. A method as claimed in claim 2 in which the peptide thiolactone has a general formula (IV) as follows: [chemical expression included] where X is any amino acid and n =1 to 10. |
| Claim: | 8. A method as claimed in claim 7 in which the peptide thiolactone molecule is: [chemical expression included] |
| Claim: | 9. A method as claimed in claim 1 in which the lactone-derived signal molecule is a furanosyl borate diester. |
| Claim: | 10. A method as claimed in claim 9 in which the furanosyl borate diester is Auto Inducer-2 (AI-2), [chemical expression included] |
| Claim: | 11. A method as claimed in claim 1 in which the lactone-derived signal molecule is Pro-AI-2 or a C 1 -C 10 saturated or unsaturated carboxylic acid derivative thereof [chemical expression included] |
| Claim: | 12. A method as claimed in claim 1 in which the antibody is a single chain antibody (scAb). |
| Claim: | 13. A method as claimed in claim 1 in which the antibody is an antibody fragment. |
| Claim: | 14. A method as claimed in claim 13 in which the antibody fragment is a single chain variable fragment (scFv) or a single domain fragment. |
