摘要:

目的:探讨牙周炎主要病原菌牙龈卟啉单胞菌(Pg)对常用抗菌药物的敏感性。方法:从成人牙周炎患者龈下菌斑中分离、通过PCR鉴定106株牙龈卟啉单胞菌的临床分离株,通过Kirby-Bauer纸片扩散法测定该菌对克林霉素、复方磺胺甲唑、四环素、头孢唑啉、乙酰螺旋霉素、头孢氨苄和青霉素G的敏感性。结果:Pg对上述药物敏感率分别是9314%、7813%、6014%、5616%、4016%、1014%和0。结论:抗牙龈卟啉单胞菌药物以其作用大小依次为克林霉素、复方磺胺甲唑、四环素、头孢唑啉、乙酰螺旋霉素和头孢氨苄,该菌对青霉素G不敏感。

Abstract:

Objective:Porphyromonas gingivalis (Pg) is one of the main putative pathogens of periodontal disease, especially of adult periodontitis. This in vitro study was aimed at observing the inhibitory activities of 7 commonly used antimicrobical drugs on 106 stains of Pg which isolated from subgingival plaques of siteswith adult periodontits.Methods:Kirby-Bauer paper diskmethodwas used in this study.Results:Pgwas highly susceptible to Clindamycin, Sulfamzthoxazole timethoprin, Tetracycline and Cefazolin, the susceptibility rates were 93.4%, 78.3%, 60.4% and 56.6% respectively.Conclusion:Majority of the strains of Pg was moderately susceptible to cefalexin and acetylspiramycin, while no strains of Pgwas susceptible to PenicillinG. The concentrations of Pg solutions (105CFU/ml, 106CFU/ml and 108CFU/ml) had notinfluence on the results. This data is helpful for clinically an- tibiotic selection of periodontal treatment.
