Abstract:

Abstract:Objective To study the inhibitory effect of antimicrobial peptides RISE-AP12® on the growth of Porphyromonas gingivalis(P. g)in vitro. Methods P. g W83 was chosen as the experimental bacterial strain. Sensitive tests were carried out by the liquid dilution method. MIC and MBC of antimicrobial peptides RISE-AP12® on P. g W83(106 CFU/mL)in vitro was determined. Results Antimicrobial peptides RISE-AP12® had the bacteriostatic and bactericidal action on 106 CFU/mL of P. g W83 when its concentration was more than 0.01 mg/mL and 0.02 mg/mL,respectively. Conclusion Antibacterial peptides RISE-AP12® has the bacteriostatic(0.01 mg/mL)and bactericidal(0.02 mg/mL)effect on P. g in vitro.

摘要:

目的 研究抗菌肽RISE-AP12®对体外培养的牙龈卟啉单胞菌(Porphyromonas gingivalis,P. g)的抗菌活性。方法 本研究于2012年10月至2013年1月在中国医科大学附属口腔医院中心实验室进行。以P. g W83为实验菌株,采用麦氏比浊法配制P. g W83混悬液(106 CFU/mL)备用,微量液体稀释法测定抗菌肽RISE-AP12®对P. g W83的最小抑菌浓度(minimal inhibitory concentration,MIC)和最小杀菌浓度(minimal bactericidal concentration,MBC)。结果 抗菌肽RISE-AP12®对106 CFU/mL P. g W83的MIC为0.01 mg/mL,MBC为0.02 mg/mL。结论 抗菌肽RISE-AP12®对浮游状态下的P. g有抑菌(MIC为0.01 mg/mL)和杀菌(MBC为0.02 mg/mL)作用。
