Abstract: The present invention provides an immunogenic composition of a lipopolysaccharide vaccine and a non-alum adjuvant. The immunogenic composition may be detoxified J5 core lipopolysaccharide of Escherichia coli non-covalently complexed with group B meningococcal outermembrane protein. Also provided are methods for preventing an infection caused by a Gram-negative bacteria in an individual via administering the immunogenic compositions to the individual.

Abstract: The invention relates to methods and compositions for treating a microbial infection. In the present invention, RNase-L activity has been shown to play an integral role in innate immunity and for defense against invading microbes. The present invention is drawn to exploiting the role of RNase-L in innate immunity for methods of treating a microbial infection. The present invention is also drawn to exploiting the role of RNase-L in innate immunity for methods of treating an immune related disease or disorder.

Abstract: The present invention describes a detoxified Gram negative J5 core lipopolysaccharide/group B meningococcal outer membrane protein complex vaccine given in conjunction with CpG 7909 adjuvant. This vaccine composition can be used for either active or passive immunization of mammals for the prevention or treatment of sepsis and infection with Gram negative bacteria. The addition of CpG to the vaccine was shown to markedly increase the antibody response in mice. Furthermore, the ability of the endotoxin vaccine in protecting against Gram-negative bacteria such as Francisella tularensis in vivo is also demonstrated herein.

Abstract: The present invention relates to a broadly reactive vaccine against Gram-negative bacteria which is composed of a biological glycan-pilus conjugate. The conjugate core is a common pilus type to which is attached the glycan of choice in vivo. Pooling of these bioconjugates produces a multivalent vaccine. These pili give high bronchial titers when delivered by the intranasal route. Mice vaccinated with pure glycosylated P. aeruginosa strain 1244 pili in this manner are protected against respiratory challenge with P. aeruginosa strain 1244. The present invention further relates to a DNA and amino acid sequence of a new gene, pilO, which is capable of glycosylating pilin of Gram-negative bacteria and uses thereof.

Abstract: An antibody to tumor necrosis factor-&agr; (anti-TNF) and an antibody to bacterial lipopolysaccharide (anti-LPS) used together in a neutropenic rat model of sepsis are shown to enhance survival of the rats relative to either antibody used alone. Pharmaceutical products including each of the components are therefore of utility in therapy of sepsis. The anti-LPS antibody included may be specific for the O-specific clain of a particular bacterial lipopolysaccharide (serotype specific antibody) but preferably recognizes the core glycolipid of lipopolysaccharide.

Abstract: Sialic acids have the ability to prevent hyposialylation of cells as comptive inhibitors of endogenous sialidase. It is now also possible to develop antibodies to mammalian sialidase that significantly reduce influx of neutrophils into inflammatory sites.

Abstract: The administration of sialidase inhibitors or sialic acid is useful as me for treating inflammatory conditions and for intervening in infectious processes in instances where pathogenicity of the disease-causing organism is increased by microbial surface interaction with host cells.
