Abstract: Compositions and methods for preventing and ameliorating Porcine respiratory and reproductive syndrome virus (PRRSV)-associated diseases in pigs by immunizing against Torque teno virus (TTV) are disclosed. Also described are methods of identifying compounds for the treatment and prevention of PRRSV-associated diseases.

Abstract: Porcine models for studying bacterial gastritis and gastric and duodenal ulcer disease caused by Campylobacter pathogens, such as C. coli are described, as well as methods of identifying vaccines and compounds for treating and/or preventing Campylobacter infection using the animal models. Also described are methods of preventing Campylobacter infection in swine, such as infection caused by C. coli, using immunogenic proteins and nucleic acids derived from Campylobacter pathogens, such as C. coli.

Abstract: Compositions and methods for treating, preventing and diagnosing Torque teno virus (TTV) infection in pigs are disclosed. Also described are methods of identifying compounds for the treatment and prevention of TTV infection, as well as TTV animal models and methods of producing the same.

Abstract: A protective cover which is releasably securable to a component having an aperture formed therethrough, such as an end yoke, is disclosed. The cover includes a generally flat circular end portion having a depending skirt portion formed about the outer periphery thereof. The skirt portion is formed integrally with the end portion and extends axially downwardly therefrom to define a hollow cylindrical protected region. First and second legs are formed integrally with the end portion and extend downwardly within and beyond the skirt portion. As they extend from the end portion, the legs diverge slightly apart from one another in inverted-V fashion. At the lower ends of the legs, respective series of shoulders are formed. The cover is installed by slightly compressing the legs together and inserting them through the aperture at one end of the component.
