Abstract:
Provided are methods for one or more of the following: preventing, inhibiting, disrupting, dispersing or treating a polymicrobial biofilm comprising a Haemophilus bacteria in vitro and/or in vivo, such as in a subject in need thereof. The method comprises or consists essentially of, or yet further consists of contacting the polymicrobial biofilm with : (i) an anti DNA binding and bending protein (DNABII) antibody or a biologically active fragment thereof; and (ii) an anti majority subunit (PilA) of type IV pilus (T4P) antibody or a biologically active fragment thereof. Additionally, the methods may further comprise contacting the polymicrobial biofilm with an antibiotic optionally comprising a β-lactam antibiotic or a sulfonamide antibiotic. Also provided are compositions and kits suitable for use in the methods.
Abstract:
Inactivated ApxIA, ApxIIA and ApxIIIA toxins, vaccines comprising said inactivated toxins and the use thereof for the immunization and protection of mammals are disclosed.
Abstract:
A vaccine composition comprising a protein, which can be detected in Haemophilus influenzae , having an amino acid sequence as described in SEQ ID NO: 1, or a fragment thereof, is described. The fragment comprises an amino acid sequence having at least 15 contiguous amino acids from the amino acid sequence of SEQ ID NO: 1, and the fragment (if necessary when coupled to a carrier) is capable of raising an immune response which recognises the polypeptide of SEQ ID NO: 1.

Abstract:
The present invention relates to compositions comprising Haemophilus influenzae Protein E and Pilin A. More particularly, the present application relates to fusion proteins and immunogenic compositions comprising Protein E and PilA, vaccines comprising such immunogenic compositions and therapeutic uses of the same.
Abstract:
The present invention provides isolated polypeptides having oligopeptide permease activity and an amino acid sequence that has at least 80 % identity with a Haemophilus parasuis OppA polypeptide. Also provided by the present invention are isolated polynucleotides that encode the polypeptides described herein, and antibody that specifically binds a polypeptide described herein. The present invention further provides genetically modified microbes, such as attenuated Haemophilus parasuis strains and other microbes that express polypeptides described herein. Also included are methods for using the polypeptides, polynucleotides, antibody, and genetically modified microbes.
Abstract:
The present invention relates to the field of animal health and in particular the causative agent of a new bacterial poultry disease caused by Gallibacteruim spp, including Gallibacterium anatis, Gallibacterium genomospecies 1 and Gallibacterium genomospecies 2. The invention provides a novel RTX toxin from said Gallibacterium species, the novel toxin being named GtxA (Gallibacterium toxin). In addition the invention provides the amino acid and nucleotide sequences of GtxA, a vaccine comprising inactivated toxoid or fragments of the toxoid as well as methods of immunizing birds to prevent said disease and to methods of diagnosing a Gallibacterium anatis infection in birds.
Abstract:
The present invention is a culture of cells of Haemophilus parasuis exhibiting attenuated pathogenicity and capable of triggering a protective immune response when administered to pigs as a live vaccine. The present invention is also a method of preparing the cell culture, a method of preparing a vaccine from the cell culture, and a live vaccine based on the cell culture. The cell culture was modified from a pathogenic parent strain by MNNG mutagenesis and was selected by complete dependence on streptomycin for growth.
Abstract:
The present invention relates to Haemophilus parasuis polynucleotides produced by recombinant technology. It also relates to polypeptides that are expressed by said polynucleotides and also to a vaccine against H.parasuis that comprises said polypeptides. In another aspect, the invention also relates to the use of polynucleotides to determine if a strain of H. parasuis is virulent or avirulent.
Abstract:
The present invention relates to a surface exposed protein (protein E; pE), a virulence factor, which can be detected in Haemophilus influenzae, having an amino acid sequence as described in SEQ ID NO 1, an immunogenic fragment of said surface exposed protein, and a recombinant immunogenic protein (pE (A) ) or truncated variants thereof based on said surface exposed protein. Nucleic acid sequences, vaccines, plasmids and phages, non human hosts, recombinant nucleic acid sequences, fusion proteins and fusion products are also described. A method of producing the said protein or truncated fragments thereof recombinantly is also disclosed.
