title: [Experimental study of R plasmid eliminating action of Coptis chinensis on E. coli].
abstract: The R plasmid curing experiment was performed in vitro with E. coli strain E. 102 bearing R plasmid as target bacteria and Coptis chinensis as elimination agent. The influence of different time on R plasmid elimination was also observed. Results showed that when the acting time was 24 hours, the cure rate of R plasmid was 2.42% and when the acting time increased to 48 hours, the cure rate elevated to 22.57%. The Missing patterns of R plasmid might be occurred in disappearence of either multiple or single resistance.
