Cloning and Sequencing of a 16 kDa Outer Membrane Protein Gene of Pasteurella multocida P52

摘要

The outer membrane proteins (OMPs) of Pasteurella multocida are potential immunogens. The 16 kDa OMP of P. multocida P52, serotype B:2, was identified as one of the major immunodominant antigens. The gene omp16, encoding a 16 kDa outer membrane protein, was amplified, cloned into a pBluescript SK(–) vector and sequenced. Complete sequence homology was observed between the 16 kDa OMP gene of P. multocida P52 (serotypes B:2) and P. multocida T16 (somatic serotype 3,4). This gene was distributed among different serotypes of P. multocida and found to localize in a 6.0 kb HindII fragment of the P. multocida genome.
