DNA encoding 85kd polypeptide useful in diagnosis of Mycoplasma infections in animals

摘要

A class of polypeptides useful in an in vitro diagnosis of Mycoplasma infection in animals is disclosed. These polypeptides are also capable of inducing an immune response in swine which were previously not exposed to Mycoplasma. Recombinant DNA methods for the production of these polypeptides and certain phage vectors and DNA sequences useful in these methods are also disclosed. Methods of vaccinating animals utilizing a vaccination composition which includes these polypeptides is also disclosed.
