Twenty-three V. parahaemolyticus strains, including 12 pandemic O3:K6 strains, were examined for their growth and production of thermostable direct hemolysin (TDH) under an anaerobic culture condition with or without presence of a bile acid, taurocholic acid (TCA). Both bacterial growth and TDH production were markedly enhanced by TCA for a majority of the strains, but the scale of the TDH production was disproportionately greater than that of the corresponding growth for 14 strains. Such enhancement was, however, not specific to the pandemic strains.
对23株副溶血性弧菌菌株进行了研究，其中包括12株大流行的O3:K6菌株，检测它们在有无胆汁酸牛磺胆酸（TCA）存在的厌氧培养条件下的生长情况以及耐热直接溶血素（TDH）的产生情况。对于大多数菌株而言，TCA显著促进了细菌生长和TDH产生，但有14株菌株的TDH产生规模比相应的生长规模增加得更多。然而，这种促进作用并非大流行菌株所特有。
