The core particles have a diameter between about 300 nm and about 4000 nm, more particularly between about 300 nm and about 2000 nm, and even more particularly between about 300 nm and about 1000 nm, are substantially spherical in shape, and have a substantially smooth surface.

Abstract: The present invention relates to a method for increasing the immunogenicity of an antigen, characterized in that the antigen is combined via stable interactions with a particulate vector, said vector containing: a non-liquid hydrophilic core, and, optionally; an outer layer of compounds chosen from the group comprising phospholipids and fatty acids. The present invention also relates to a product thereby obtained and to a pharmaceutical composition containing such product.

Abstract: A signal amplification system comprises a bacterial multi-hybrid system, and more preferably a two-hybrid system, of at least two chimeric polypeptides containing a first chimeric polypeptide corresponding to a first fragment of an enzyme and a second chimeric polypeptide corresponding to a second fragment of an enzyme or a modulating substance capable of activating said enzyme. The first fragment is fused to a molecule of interest and the second fragment or the modulating substance is fused to a target ligand. The activity of the enzyme is restored by the in vivo interaction between the molecule of interest and the target ligand. Signal amplification is generated and, for example, triggers transcriptional activation. The signal amplification system is useful in a method of selecting a molecule of interest, which is capable of binding to target ligand, wherein the interaction between the molecule of interest and the target ligand is detected with the signal amplification system as a kit therefor.

Abstract: The present invention discloses novel antibiotic peptides, including naturally occurring peptides. The present invention also includes the nucleic acid sequences encoding such peptides and the corresponding amino acid sequences. Methods of identifying, making, and using the antibiotic peptides are also disclosed. The present invention further provides novel proteins involved in the regulation of bacterial autolysis.

Abstract: The bacteriophage has a high level of specificity to a certain specific pathogenic bacterium so that the bacteriophage can surely kill the pathogenic bacterium as a host through phogocytic action. The bio-bactericidal material containing the bacteriophage can be applied to food such as fresh food, etc., and to places, etc. or to even persons for cooking food material such as restaurants, school kitchens, etc., or any other thing which requires disinfection from pathogenic bacteria, and it can kill pathogenic bacteria. The bio-bactericidal material containing a cocktail of two or more different kinds of the bacteriophages can kill corresponding kinds of pathogenic bacteria concurrently. Further, the phage can infect only the pathogenic bacterium as a host bacterium, and does not infect persons, making it very safe and useful.
