Abstract

The outer membrane protein of Oma87 from Pasteurella multocida A:1 has significant similarity to the D15 protective antigen of Haemophilus influenzae ( Ruffolo and Adler, 1996). Four fragments of Oma87 from a P. multocida serotype D strain were cloned into a pGEX expression vector and transformed into E. coli JM105. Western blot analysis revealed that convalescent chicken sera reacted with only GST-F1 fusion protein which contained amino acids 18 through to 130 of Oma87 fused to the GST protein. Vaccination with the GST-F1 protein failed to protect chickens against challenge with a virulent P. multocida serotype A.
