ABSTRACT
OBJECTIVE To investigate ?-lactamase coding genes and oprD2 gene in multidrug-resistant Pseudomonas aeruginosa isolated.METHODS Polymerase chain reaction(PCR) was used to detect various ?-lactamase coding genes including TEM,SHV,OXA,PER,GES,IMP,VIM,plasmid type AmpC ?-lactamase DHA,MIR and oprD2 in 20 strains of P.aeruginosa.RESULTS The detection rate of ?-lactamase coding genes plasmid type AmpC,VIM,TEM,SHV,OXA and IMP were 15%,5%,15%,10%,10% and 5%,respectively,the loss rate of oprD2 was 25%,but PER and GES genes were negative.CONCLUSIONS The study indicated that the P.aeruginosa is carrying genes of DHA,TEM,SHV,OXA,VIM,IMP and being lost oprD2 gene,the latter is the essential resistance mechanism of P.aeruginosa to beta-lactam antibiotics in local area.
