Abstract: An investigation was carried out to compare the effect of growth of P. multocida type A of pig origin in iron restricted and in iron sufficient media on the basis of their outer membrane protein extract. Pasteurella multocida serotype A was cultured in two ways. In one process only BHI medium was used and on the other process same medium was used which was supplemented with 2, 2’- Dipyridyl (iron-restricted medium). Both these cultures were used to obtain Outer Membrane Proteins (OMPs) by extraction of bacterial cells with 1% Sarcosyl. Separation of the OMPs in SDS-PAGE showed that OMPs were mixture of protein fraction with molecular weight ranging from 110 to 22.6 kDa in case of iron-restricted OMP and 47.3 to 29.9 kDa in case of iron sufficient OMP. The OMP with molecular masses 29.9 kDa grew in both iron-restricted as well as in iron sufficient medium.
