Abstract:
Objective: To study the antibacterial activity in vitro of Xiyanping injection combined with cefoxitin, cefuroxime, ceftriaxone, cefmenoxime, amikacin, levofloxacin and meropenem against staphylococcus aureus, escherichia coli, klebsiella pneumoniae, pseudomonas aeruginosa and acinetobacter bauman.Methods: Minimum inhibitory concentration (MIC) of the 7 kinds of antimicrobial agents used individually or combined with Xiyanping injection on germs were determined respectively on 96 plates by using the agar dilution method and the checkerboard method.Fractional inhibitory concentration index (FICI) was calculated to evaluate the antibacterial activity of Xiyanping injection combined with the 7 kinds of antimicrobial agents in vitro.Results: MIC of Xiyanping injection combined with cefoxitin was the same as that of cefoxitin used individually on escherichia coli.MIC of levofloxacin combined with Xiyanping injection showed no difference with that of levofloxacin used individually on klebsiella pneumoniae.Besides, Xiyanping injection could increase the MIC of the other antimicrobial agents on germs.Conclusion: Xiyanping injection combined with antimicrobial agents on staphylococcus aureus, escherichia coli, klebsiella pneumoniae shows antagonistic and irrelevant relationship.
