Abstract: Compositions and methods for treating, preventing and diagnosing Helicobacter infection are disclosed. The methods use proteins and/or nucleic acids derived from Helicobacter cerdo, a new pathogen isolated from swine. In addition, porcine models for studying bacterial gastritis and gastric and duodenal ulcer disease caused by Helicobacter pathogens, such as H. pylori and H. cerdo are described, as well as methods of identifying vaccines and compounds for treating and/or preventing Helicobacter infection using the animal models. Also described are methods of preventing Helicobacter infection in swine, such as infection caused by H. cerdo, using immunogenic proteins and nucleic acids derived from Helicobacter pathogens, such as H. pylori.

Abstract: Porcine circovirus-2 (PCV-2) is a recently identified agent wherein the potential spectrum of PCV-2-associated disease has been expanded by evidence of vertical and sexual transmission and associated reproductive failure in swine populations. PCV-2 was isolated from a litter of aborted piglets from a farm experiencing late term abortions and stillbirths. Severe, diffuse myocarditis was present in one piglet associated with extensive immunohistochemical staining for PCV-2 antigen. Variable amounts of PCV-2 antigen were also present in liver, lung and kidney of multiple fetuses.
