摘要:
The present invention broadly relates to immunogenic compositions for administering to a host susceptible to Moraxella catarrhalis infection. More particularly, the invention is directed to the identification of cross-reactive epitope sequences of the CopB protein of Moraxella catarrhalis.
摘要:
A method is provided for identifying, isolating, and producing htrB mutants of gram-negative bacterial pathogens. The method comprises mutating the htrB gene of a gram-negative bacterial pathogen so that there is a lack of a functional htrB protein, resulting in a mutant that lacks one or more secondary acyl chains contained in the wild type gram-negative bacterial pathogen, and displays substantially reduced toxicity as compared to the wild type strain. Also, the present invention provides methods for using a vaccine formulation containing the htrB mutant, the endotoxin isolated therefrom, or the endotoxin isolated therefrom which is then conjugated to a carrier protein, to immunize an individual against infections caused by gram-negative bacterial pathogens by administering a prophylactically effective amount of the vaccine formulation.

摘要:
A composition for co-injection of an animal against a gram-negative pathogen which comprises an effective dose of a gram-negative type lipopolysaccharide devoid of O-carbohydrate side-chains and a vaccine derived from said pathogen. Methods of co-injection of an animal to protect the animal against gram-negative pathogens.
摘要:
The invention provides methods of formulating an anti-inflammatory composition for treating inflammatory conditions in a specific organ or tissue. The method involves selecting at least one pathogen that is pathogenic in the specific organ or tissue; producing an antigenic composition comprising antigenic determinants that together are specific for the pathogen; and formulating the antigenic composition for administration as an anti-inflammatory composition capable of eliciting an anti-inflammatory response in the specific organ or tissue, wherein the condition characterized by inflammation is not a cancer. In embodiments of the invention, a cancer is situated in the specific organ or tissue.
摘要:
The disclosure provides immunogenic compositions comprising a polypeptide comprising a C-lobe domain or an N-lobe domain of a HIBP surface receptor protein obtainable from or obtained from a Gram-negative bacterial species. The HIBP surface receptor proteins have been modified in such a manner that they are unable to bind host iron binding protein. Methods of making and using these immunogenic positions to prepare animal and human vaccines are also provided.
摘要:
The present invention relates to compositions comprising Moraxella catarrhalis (M. catarrhalis) Ubiquitous surface protein A2 (UspA2). More particularly, the present application relates to UspA2 protein constructs and immunogenic compositions comprising the constructs, vaccines comprising such immunogenic compositions and therapeutic uses of the same. The invention further relates to compositions comprising UspA2 in combination with at least one antigen from Haemophilus influenzae, immunogenic compositions comprising the antigens, vaccines comprising such immunogenic compositions and therapeutic uses of the same.
摘要:
A preparation of an antigen of one or more pathogenic bacterial species for use in treating a cancer in a specific organ, tissue or cell in a subject, wherein the pathogenic bacterial species is pathogenic in the corresponding specific organ, tissue or cell in a healthy subject. Suitably, the preparation comprises one or more attenuated bacteria.
