Abstract
Protein profiles of selected Salmonella serovars were compared with E. coli to identify genus specific protein(s) for Salmonella. The PDP formed of different Salmonella serovars were compared with E. coli O78 when subjected to SDS-PAGE yielded 11, 15, 15, 11 and 14 bands in S. Bareilly, S. Gallinarum, S. Typhimurium and S. Weltevreden and E. coli O78 respectively. The bands produced were compared with each other. It was found that S. Weltevreden shared 7 bands with E. coli O78, A protein of molecular weight 20.89 kDa was found in all Salmonella serovars, but not in E. coli O78 suggesting its genus specific attribute.
