Pasteurella piscicida grown in a glucose-rich medium produces a capsule that can be see under light and electron microscopy. The capsular polysaccharide was purified and characterized by chemical and HPLC analysis. The polymer has the composition glucose/mannose/N-acetylgalactosamine/galacturonic acid/acetic acid in the molar ratios of approximately 2.5:1.3:0.5:0.4:2.5. The polysaccharide was immunogenic in rabbits and did not cross-react with antibodies against the O-antigen lipopolysaccharide.
