Clinical Distribution of Pseudomonas Aeruginosa of Three Colony Morphologies and Analysis of Their Drug Resistance
Abstract：Objective:Distribution of Pseudomonas aeruginosa colony morphology in clinical infections and susceptibility to commonly used antibiotics. Methods:15 kinds of antimicrobial agents in vitro susceptibility testing of Pseudomonas aeruginosa isolated our hospital in June 2010-2012 in June from clinical departments censorship specimens.Results:Among the 208 strains of Pseudomonas aeruginosa,the smooth colony accounted for 68.8%,mucoid colony 19.7%, and Escherichia coli colony 11.5%.Among the three types,mucoid colony had the highest drug resistance rate.Pseudomonas aeruginosa against infection drug resistance rate to Imipenem,Meropenem,Amikacin,Polymyxin,Piperacillin,Piperacillin/Tazobactam,Levofloxacin respectively is lowest.Cefazolin,Ampicillin/Sulbactam, sulfamethoxazole highest resistance rate,and the existence of multi-drug resistant.Conclusion:There was single and multiple antibiotic resistance in Pseudomonas aeruginosa,especially to mucoid type colony,higher resistant than others.As to decrease infection rate of the bacteria,precautionary measures should be enhanced.
