SDS AGAR (SODIUM DODECYL SULPHATE POLYMYXIN SUCROSE AGAR) (as per APHA)

Description

Vibrio vulnificus is a gram-negative, motile, curved, rod-shaped bacterium. Present in marine environments such as estuaries, brackish ponds, or coastal areas, V. vulnificus is closely related to V. cholera. The causative agent of cholera. V. vulnificus causes an infection often incurred after eating seafood, especially oysters. The bacteria can also enter the body through open wounds when swimming or wading in infected waters. SDS Agar is formulated as described by Bryant et al for differentiation of V. vulnificus from other Vibrio. SDS Agar is recommended by APHA for isolation and enumeration of V. vulnificus from sea foods. V. vulnificus is a causative agent of septicemic shock associated with consumption of raw oysters. V. vulnificus forms distinctive colonies which are round, opaque, blue to brownish about 2 to 3 mm in diameter with a blue opaque halo around each colony.
