摘要: 目的 观察红霉素对铜绿假单胞菌(pseudomonas aeruginosa, PA) 抗巨噬细胞吞噬能力的影响。方法 铜绿假单胞菌ATCC 27853 菌株接种于两组LB 液体培养基中, 一组加入低浓度红霉素, 另一组不加红霉素为空白对照组, 培养18 h 后, 两组PA 与小鼠腹腔巨噬细胞分别共同孵育2 h, 通过显微镜观察巨噬细胞吞噬率的变化。结果 经过18 h 的细菌培养和2 h 的细菌与巨噬细胞共同孵育, 光镜下看到巨噬细胞对低浓度红霉素组PA 的吞噬率增加。电镜下看到加红霉素组的巨噬细胞伪足增多,吞噬活性增强。结论 低浓度红霉素能抑制铜绿假单胞菌的毒力因子, 从而增加巨噬细胞的吞噬率。

Abstract: AIM: To observe the effect of phagotrophic ability of macrophage on pseudomonas aeruginosa which was cocultured with low concentration of erythromycin.METHODS: The pseudomonas aeruginosa ATCC 27853 was cultured in LB both with low concentration of erythromycin (GrouPA) and without erythromycin (GrouPB) for 18 h separately, then incubated with macrophage from murine abdominal cavity for 2 h.The ratio of phagocytosis of macrophage was determined by microscope detection.RESULTS: The ratio of phagocytosis of grouPA in which erythromycin was added was higher than the grouPB, and the pseudopodia of macrophage were increased in the grouPA under electron microscope.CONCLUSION: Low concentration of erythromycin may enhance the phagocytosis ability of macrophage in vitro by influencing the virulent factors of PA.

Key words: erythromycin, pseudomonas aeruginosa, macrophage
