The virulence mechanisms of Vibrio vulnificus biotype 2 have been studied and compared with those of biotype 1 in mice as the experimental animals. Biotype 2 isolates from European eels were as virulent for mice as biotype 1 strains (50% lethal dose, about 10(5) CFU per mouse); a septicemic infection developed in less than 24 h. These strains had several properties in common with biotype 1 organisms including capsule expression, uptake of various iron sources, and production of exoproteins, whose role in mouse virulence has been demonstrated. We also discuss the implication of biotype 2 strains in human infections.
已经对创伤弧菌生物型2的毒力机制进行了研究，并在小鼠作为实验动物的情况下与生物型1的毒力机制进行了比较。从欧洲鳗鱼分离出的生物型2菌株对小鼠的毒力与生物型1菌株相同（半数致死剂量，约每只小鼠10(5) CFU）；在不到24小时内就会发展为败血症感染。这些菌株与生物型1菌株有几个共同特性，包括荚膜表达、摄取各种铁源以及产生外蛋白，其在小鼠毒力中的作用已得到证实。我们还讨论了生物型2菌株在人类感染中的意义。
