Study on loss of OprD_2 in imipenem-resistant Pseudomonas aeruginosa / 临床检验杂志

ABSTRACT

Objective To investigate the loss of outer membrane protein D2 (OprD2) gene in imipenem-resistant Pseudomonas aeruginosa.Methods The minimal inhibitory concentrations (MIC) of 10 antimicrobial agents against 80 strains of imipenem-resistant clinical isolates were determined by agar dilution method.PCR was used to detect OprD2 gene.Results PCR results showed that 44 of the 80 isolates of imipenem-resistant P.aeruginosa were positive for OprD2 gene.There was significant difference (P
