摘要:
Treatment and diagnosis of P. aeruginosa infection or colonization is achieved in accordance with this invention by the discovery of a polypeptide which is smaller than the naturally occurring P. aeruginosa pillin protein. The pure polypeptide comprises at least one amino acid residue sequence containing about twelve amino acid residues and up to about twenty amino acid residues that define a sequence capable of immunologically mimicking an antigenic determinant cite of P. aeruginosa pilin. This amino acid residue sequence can repeat as a unit one or more times in the same polypeptide molecule. More than one of such repeating units and more than one repeating unit of the same type can be present in a single polypeptide molecule. The polypeptides act an antigens or immunogens and antibodies may be raised to the immunogens and a vaccine prepared suitable for the prevention of P. aeruginosa infection.
摘要:
A peptide having a sequence corresponding to a C-terminal portion of the Pseudomonas aeruginosa pilin protein is disclosed. The peptide is cross-reactive with surface peptides present in certain bacterial and fungal microorganisms, and is effective in inhibiting binding of such organisms to target epithelial cells. The peptide may also be employed in a vaccine composition, for producing immunity against such cross-reactive microorganisms. Also disclosed are methods of preparing peptides which are cross-reactive with the P. aeruginosa pilin peptide, and chimeric monoclonal antibodies immunoreactive with the pilin peptide.

摘要:
The invention described includes methods and compositions useful in preventing infection by Pseudomonas aeruginosa and related organisms. Diclosed is a peptide having the sequence corresponding to an antigenic site in the protein exoenzyme S which is antigenically similar to a C-terminal portion of the Pseudomonas aeruginosa pilin protein. The peptide is cross-reactive with surface peptides present in certain bacterial and fungal microorganisms, and is effective in inhibiting binding of such organisms to target epithelial cells. The peptide may also be employed in a vaccine composition, for producing immunity against Pseudomonas aeruginosa as well as against such cross-reactive microorganisms.

摘要:
The present invention relates to a composition, device and method for preventing or inhibiting biofilm formation on biotic or abiotic surfaces. The composition comprises a peptide based on the C-terminal receptor binding domain of Pseudomonas aeruginosa type IV pilin, which binds to an abiotic surface (e.g., steel, plastic) with high affinity and prevents binding of a variety of P. aeruginosa strains to the surface. The inventive composition represents a non-toxic inhibitor for biofilm formation, particularly on an abiotic surface, which is responsible for a large number of problematic diseases and massive economic losses. The inventive method is useful as a safe and environmentally friendly means of modifying a surface of a variety of biomedical, nanotechnological, and biotechnological devices or articles.

摘要:
A method of treating Candida albicans infection is disclosed. In one embodiment, for treatment of oral or vaginal infection, the treatment is by topical application of a composition of conjugates that are each composed of a carrier structure and multiple .beta.GalNac(1-4).beta.Gal moieties attached to the structure. In another embodiment, for treatment of systemic infection, the treatment is by parenteral administration of a humanized form of a mouse monoclonal antibody produced by mouse hybridoma cell line Fm16 or cell line PK99H.
