ERIC-PCR Fingerprinting Related with oprD_2 Gene of Pseudomonas aeruginosa Isolates Resistant to Imipenem / 中华医院感染学杂志

0.05).Thirty genotypes were got from 54 strains by ERIC-PCR.CONCLUSIONS There isn′t significant difference on the absence rate of oprD2 gene in Tianjin and it gives us a hint that other factors can also result in the prevalence of IRPA.The existence of prevalence of IRPA clone in some departments advises us to effectively control the IRPA in hospital.

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

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
