Abstract Objective：To study the Radix Paeoniae Rubra granules on the pan drug resistant Acinetobacter Bauman in vitro antibacterial activity，for the treatment of infectious disease caused by the bacterium infection clinical exploration.Method：Clinical were collected from January 2013 to June 2014 in our hospital microbiology laboratory of pathogenic bacteria culture and drug-sensitivity specimens，the bacteria identification and drug sensitivity test of Pan drug resistant
Acinetobacter meets Bauman of 50 strains of bacteria，the determination of the minimal inhibitory concentration of the strain of aeoniae granules by micro broth dilution susceptibility test，in vitro antibacterial observed the effect of Radix Paeoniae Rubra ranules.Result：The OD value of Radix Paeoniae Rubra particle solution of different concentration on the pan drug resistant cinetobacter Bauman OD value were less than the positive control hole，and with the increase of drug concentration，the OD alue was smaller，indicating that the inhibition of Radix Paeoniae Rubra particle solution were，and with the increase of drug
concentration，the stronger bacteriostasis.Conclusion：Radix Paeoniae granules on the pan drug resistant Acinetobacter Bauman an inhibit its growth in vitro antibacterial test.
