Objective:To observe the influence of the Compound Qingre Granule-Serum(SQ) on bacteria-resistance under antibiotics of low concentration.Methods:According to serum pharmacology methods.SQ with the strongest bacteriostatic effect was used for the following experiment.E.coli cells ATCC25922 were incubated under the culture media with low concentration of Neomycin and SQ
compared with blank serum
blank culture media and low concentration of Neomycin.The bacteriostasis diameter(mm) of Neomycin
Kanamycin
Gentamicin
Stmycin and Ampicill was tested for culture cells to determine the induced germ's drug resistance.Results:SQ has bacteriostatic action to ATCC25922
its bacteriostasis diameter reached to 10 mm;After being induced for 30 generations
increased resistance of ATCC25922 to Neomycin happened easily
as well as multi-resistance to Kanamycin and Ampicill at the same time.When SQ was put in the inducing system
the bacteria only appeared simple-resistance to Neomycin in the 40th generation
and it always keep sensitive to Kanamycin
Gentamicin
Stmycin and Ampicill.Conclusion:SQ has the effect of delaying and controlling the bacteria multiple-drug resistance with low concentration of antibiotics.
