Abstract:
OBJECTIVE To investigate the genetic background and antibiotic resistance of continuously isolated P.aeruginosa strains in Shaoxing.METHODS Eighty six strains of P.aeruginosa were isolated from hospitalized patients,and drug-resistant genes,integrons and transposons were detected by PCR.RESULTS The positive rates of blaCARB,blaVIM,blaDHA,blaTEM,ant(2″)-Ⅰ,aac(6')-Ⅱ,aac(6')-Ⅰb and ant(3″)-Ⅰ were 30.2%,14.0%,3.5%,1.1%,27.9%,24.4%,15.1% and 4.7%.There were clone transmitted phenomenon.CONCLUSIONS There are very high positive percentages of blaCARB,blaVIM,ant(2″)-Ⅰ,aac(6')-Ⅱ,and aac(6')-Ⅰb genes in continuously isolated P.aeruginosa strains.P.aeruginosa can induce clone transmitted hospital infection and it has fulminant prevalence.
