Expression of listeriolysin O of Listeria monocytogenes as a function of different growth conditions was studied by performing a direct hemolysin assay, immunoblotting experiments, and an enzyme-linked immunosorbent assay. Expression of listeriolysin O was reduced at a lower growth temperatures (26 degrees C) and at higher glucose concentrations (> or = 0.3%) in the growth media. The effect of glucose appeared to be due to a change in the pH of the growth media.
通过进行直接溶血素测定、免疫印迹实验和酶联免疫吸附测定，研究了不同生长条件下单增李斯特菌溶血素O的表达情况。溶血素O的表达在较低生长温度（26℃）和生长培养基中较高葡萄糖浓度（≥0.3%）时降低。葡萄糖的影响似乎是由于生长培养基pH值的变化。
