ABSTRACT:
Surface polysaccharide and somatic polysaccharide are recovered from gram-negative nonenteric pathogenic bacilli in purified forms that are useful as veterinary acellular vaccines either individually or combined. The surface polysaccharide recovery process involves shearing the surface polysaccharide and somatic polysaccharide from the cell membrane, removing the bacteria, isolating the surface polysaccharide by precipitation with Cetavlon, solubilizing the precipitate, and removing nucleic acids by ethanol precipitation. The somatic polysaccharide is recovered from the supernatant remaining after the Cetavlon precipitation by ethanol precipitation.
