Answer

The O139 Bengal strain of V cholerae has a very similar pathogenic mechanism except that it produces a novel O139 lipopolysaccharide (LPS) and an immunologically related O-antigen capsule. These 2 features enhance its virulence and increase its resistance to human serum in vitro and occasional development of O139 bacteremia.
