Abstract: A modified p145 peptide having enhanced mucosal immunogenicity for use in eliciting a mucosal immune response to group A streptococcal bacteria in a mammal such as a human. Intramuscular administration of the modified p145 peptide may be particularly efficacious. An S2 peptide or variant may be co-administered with the modified p145 peptide to enhance the immune response.

Abstract: A modified p145 peptide having enhanced mucosal immunogenicity for use in eliciting a mucosal immune response to group A Streptococcal bacteria in a mammal such as a human. Intramuscular administration of the modified p145 5 peptide may be particularly efficacious. An S2 peptide or variant may be co-administered with the modified p145 peptide to enhance the immune response.

Abstract: The present invention provides compositions, including pharmaceutical compositions, comprising an amount of an antibody, antibody fragment or antibody conjugate sufficient to treat Group A streptococcus (GAS) infection or complication thereof in a subject or a disease or complication associated with GAS infection in a subject wherein said antibody, antibody fragment or antibody conjugate binds immunospecifically to a B-cell epitope of GAS M-protein. The present invention also provides methods for the prophylactic or therapeutic treatment of infection by GAS and complications thereof comprising administering the compositions to a subject in need thereof.

Abstract: The present invention relates generally to chimeric peptides comprising one or more protective epitopes in a conformation enabling immunological interactivity and to vaccine compositions comprising same. The present invention is particularly directed to a chimeric peptide capable of inducing protecting antibodies against Group A streptococci.

Abstract: Effective stimulation of immune responses is achieved through the use of a group A streptococcal antigen combined with proteosome adjuvant. The compositions are provided in particular for intranasal administration. The vaccine compositions are provided for use in inducing an immune response in an individual for the treatment or prophylaxis of group A streptococcal infection in an individual, preferably via prevention or reduction of colonisation of the throat following intranasal administration.

Abstract: The present invention provides polymers incorporating peptides. The polymers comprise polymarised units of (1) CH2═CR4—CO—X—R1 and (2) CH2═CR3—CO—R2 and optionally one or more other monomers, in which R1 is a peptide. Each R1 may be the same, or is preferably different. In another embodiment the present invention provides polymers formed from CH2═CR4—CO—X—R1 and optionally one or more other monomers, in which X is a spacer having a length equivalent to 1 to 30 single C—C bonds and R1 is a peptide, each R1 being the same or different. The invention further relates to methods producing the polymers and methods of inducing an immune response using the polmers.

Abstract: A purified peptide which induces proliferation or activation of cytotoxic T cells specifically against circumsporozoite protein of P. falciparum is described. The peptide has an amino acid sequence KPKDELDYENDIEKKICKMEKCS in single letter amino acid code.
