A construct of the Mycoplasma pulmonis (MP) genomic library, using randomly sheared DNA, was cloned in λgt11 and transfected into C600 Escherichia coli organisms. Clones of E. coli expressing a fusion protein reactive with anti-MP and monospecific serum were transferred orally or intravenously into Balb/c mice. Expression of the fusion protein was induced by adding isopropyl-β-D-thiogalactopyranoside to the drinking water. This vaccination protocol led to local and systemic antibody formation, to generation of immune lymphocytes and to protection against large numbers of virulent MP organisms. This approach might be generally successful in preventing infectious disease.
