Objective  To systematically review the resistance of pseudomonas aeruginosa to quinolone in China.
Methods  Such databases as CNKI, WanFang Data, CBM, VIP, PubMed, EMbase and The Cochrane Library were electronically searched from inception to December 2012, for relevant studies on the resistance mechanism of pseudomonas aeruginosa to quinolone. Two reviewers independently screened literature according to inclusion and exclusion criteria. Then, meta-analysis was performed using RevMan 5.0 software.
Results  Totally 19 studies were included, involving 723 strains of quinolone-resistant pseudomonas aeruginosa. The statistical results showed that, in the areas to the north of Huai River, the detection rates of gyrA, gyrB, parC and parE were 88.0%, 13.3%, 31.4% and 16.7%, respectively; and in the areas to the south of Huai River, they were 64.6%, 50.0%, 35.4% and 16.7%, respectively. The detection rates of plasmid mediated resistant genes aac (6’)-Ib-cr was 0 (0/66) in the areas to the north of Huai River, and 39% (25/64) in the areas to the south of Huai River. The outer membrane protein expression rate of active efflux system was 68.1%.
Conclusion  In China, gyrA gene mutation and the active efflux system mainly account for pseudomonas aeruginosa’s resistance to quinolone. DNA topoisomerase IV abnormalities and plasmid mediated resistance is the secondary mechanism.
