Surface antigens of swine mycoplasma, such antigens prepared by recombinant DNA methods, a swine mycoplasma vaccine, based on such antigens, methods of treating swine to prevent enzootic pneumonia using that vaccine, and diagnostic tests based on these antigens or antibodies raised against them for detecting the presence of swine mycoplasma infections in swine herds, and DNA sequences that code for such antigens are disclosed.

DNA sequences coding for Mycoplasma hypopneumoniae surface antigens,

Small peptides that display the specificity of FMD viral antigens. The peptides are useful in compositions and methods for the protection of animals for at least some time from FMD viral infections. The peptides of this invention may be prepared by conventional synthetic methods, recombinant DNA technology or a combination of the two. They may also be modified in composition and conformation to improve further their specific antigenic properties.
