Abstract: The disclosure provides a method for administering an agent to an avian species by in ovo delivery of an implant releasably containing the agent. In one embodiment, the method is particularly advantageous for stimulating an immune response in a bird by in ovo administration of a biocompatible implant releasably containing an immunogen. The implant can provide for sustained or delayed release of the immunogen or both. The amount of immunogen that is released from the implant into the bird is preferably sufficient to effectively stimulate a primary immune response to the immunogen. Other agents which can be administered according to the method of the invention are disclosed.

Abstract: The present invention provides compositions including siderophore receptor polypeptides and porins from gram negative microbes, and preferably, lipopolysaccarhide at a concentration of no greater than about 10.0 endotoxin units per milliliter. The present invention also provides methods of making and methods of using such compositions.

Abstract: The present invention provides isolated polypeptides isolatable from a Fusobacterium spp. Also provided by the present invention are compositions that include one or more of the polypeptides, and methods for making and methods for using the polypeptides.

Abstract: The invention provides a vaccine for immunizing poultry and other animals against infection by a gram-negative bacteria, and a method of immunizing an animal using the vaccine. The vaccine may contain purified siderophore receptor proteins derived from a single strain or species of gram-negative bacteria or other organism, which are cross-reactive with siderophores produced by two or more strains, species or genera of gram-negative bacteria. The invention further provides a process for isolating and purifying the siderophore receptor proteins, and for preparing a vaccine containing the proteins. Also provided is a method for diagnosing gram-negative sepsis.

Abstract: The present invention provides compositions including polypeptides having the characteristics of polypeptides expressed by a reference microbe such E. coli or Salmonella. Examples of Salmonella strains that can be used include, for instance, S. enterica serovar Newport, S. enterica serovar Enteritidis, S. enterica serovar Typhimurium, and S. enterica serovar Dublin. Also provided are compositions including polypeptides having a particular molecular weight and a mass fingerprint that includes polypeptide fragments having a particular set of masses, or polypeptides having an amino acid sequence with at least about 95% identity with an amino acid sequence, wherein the polypeptide has seroreactive activity. The present invention also provides methods of making and methods of using such compositions.

Abstract: The present invention provides isolated metal regulated polypeptides obtainable from a Campylobacter spp., and compositions including the polypeptides. The present invention also includes methods for using the compositions disclosed herein, including methods for treating in infection in a subject, for treating a condition caused by a Campylobacter spp., and for decreasing colonization of an animal.
