The group disposed by Acetylspiramycin doesn"t show parallel results; The strip gray scale of exotoxin A decreased gradually with the increasing dosages of Azithromycin and Roxithromycin, which doesn"t show in group disposed by Acetylspiramycin and group PAO-JP2; The strip gray scale of lasR, detected by RT-PCR, decreased gradually with the increasing dosages of Azithromycin, which doesnt show in group PAO-JP2.Conclusions: There were obvious differences between PAO1 and PAO-JP2 in biology characteristics in vitro.

本研究发现大环内酯类药物在生物被膜培养过程中分别处理PAO1、PAO-JP2，结果提示大环内酯类药物(14、15元环)通过对QS系统的影响可有效抑制铜绿假单胞菌生物被膜的形成；通过QS系统有效抑制铜绿假单胞菌的毒力因子的产生，16元环的大环内酯类药物乙酰螺旋霉未见上述结论；lasR基因的反转录结果提示阿奇霉素可在转录水平抑制QS系统发挥其作用。
