CAD and Sepsis: Nevertheless, several V. vulnificus factors have been reported to play a role in human septicemia such as a potassium pump [14], a capsular polysaccharide (CPS) [15–18], a surface lipoprotein [19], the siderophore vulnibactin [16], the flagellum [20,21], the RtxA (or MARTX) toxin [22,23], and surface modifications by sialic acid moieties [24], all of which either contribute to growth in serum (potassium pump, siderophore...) or inflammation (CPS, lipoprotein, RtxA...) or immune evasion (RtxA, CPS.).
