Characterization of immunodominant and potentially protective epitopes of Mannheimia haemolytica serotype 1 outer membrane lipoprotein PlpE.

ABSTRACT: Mannheimia haemolytica serotype 1 (S1) is the most common bacterial isolate found in shipping fever pneumonia in beef cattle. Currently used vaccines against M. haemolytica do not provide complete protection against the disease. Research with M. haemolytica outer membrane proteins (OMPs) has shown that antibodies to one particular OMP from S1, PlpE, may be important in immunity. In a recently published work, members of our laboratory showed that recombinant PlpE (rPlpE) is highly immunogenic when injected subcutaneously into cattle and that the acquired immunity markedly enhanced resistance to experimental challenge (A. W. Confer, S. Ayalew, R. J. Panciera, M. Montelongo, L. C. Whitworth, and J. D. Hammer, Vaccine 21:2821-2829, 2003). The objective of this work was to identify epitopes of
