摘要：
Twenty strains of V. vulnificus isolated from the environment were investigated for characteristics related to their infectivity such as colonial morphology, enzymatic activity and animal assays. The presence of DNase, chitinase. amylase, lecithinase and gelatinase was observed in 100% of the st:rains. haemolytic activity was absent. and variable results were obtained in elastase, collagenase and chondroitinase. In the animal assays. 70% of the strains were lethal to adult mice, while 45 % caused fluid accumulation in suckling mice. Although all strains had opaque colonies, only 3 of the 20 had the three enzymes elastase, collagenase and gelatinase, and only one of these was virulent in animal assays.
