ABSTRACT
Objective To investigate the molecular epidemiology and risk factors of the expression of the efflux pumps of multidrug resistant Pseudomonas aeruginosa (Pa). Method From April 2014 to October 2014 , clinical features of 100 patients infected with multidrug resistant Pa were retrospectivly analyzed . Results MexAB-OprM was expressed in all multidrug resistant Pa strains (100%). The expression rates of MexEF-OprN and MexCD-OprJin the multidrug resistant Pa strains were 50% and 36%, respectively. The risk factor of the three efflux pumps expression was analyzed and the results were as follows the use of carbapenems and glycopeptides antibiotics was the risk factor of MexAB-OprM overexpression which was induced. The use of macrolide and carbapenems antibiotics was the risk factor of the induced MexEF-OprN and MexCD-OprJ expression. Invasive procedures, low WBC, anaemia, chronic fundamental disease and hospitalized in ICU ward were the common risk factors of communicable expression or overexpression of the three efflux pumps. Invasive procedures, low WBC, anaemia, chronic fundamental disease and hospitalized in ICU ward were commonly independent risk factors of expression of the three efflux pumps. Conclusion The normalized use of carbapenems and glycopeptides antibiotics , the reduction of unnecessary invasive procedures , the severely grasped standard of hospitalized in ICU ward , curing the fundamental diseases and improving the immunonity played important roles in the prevention of the expression or overexpression of the efflux pumps of multidrug resistant Pa.
