The Inhibitory Effect of Zinc on Imipenem and Meropenem Susceptibility of Pseudomonas aeruginosa

چکیده
393 Abstract: In this study we have showed that zinc ion has an inhibitory activity on imipenem and meropenem suspectibility of Pseudomonas aeruginosa. When zinc ion concentration of Mueller-Hinthon agar (MHA) media was gradually increased the zone diameters of imipenem and meropenem gradually decreased. So we concluded that zinc concentration in the media might effect imipenem and meropenem susceptibility of Pseudomonas aeruginosa and might indicate false resistance to imipenem and meropenem. Therefore the use of these antipseudomonal antibiotics in Pseudomonas infections may be restricted.

Effect of zinc concentration in Mueller-Hinton agar on susceptibility of Pseudomonas aeruginosa to meropenem.
The susceptibility of Pseudomonas aeruginosa to imipenem has been shown to vary according to zinc concentration in the media. MICs of imipenem for 68 unique clinical isolates of P. aeruginosa were determined in media supplemented with zinc at concentrations between 0.5 and 6.0 micrograms/ml. In agar containing up to 3 micrograms of zinc/ml, 75 to 82% of the strains were susceptible to imipenem ...

متن کاملEffect of Subinhibitory concentrations of imipenem and piperacillin on transcriptional expression of algD and lasB genes in Pseudomonas aeruginosa
Sub Minimal Inhibitory concentrations (sub-MIC) of antibiotics, although not able to kill bacteria, can be effect on their physico- chemical characteristics and functions. This study aimed to investigate the effect of sub-MIC of imipenem and piperacillin on the transcriptional expression of virulence related genes algD and lasB in Pseudomonas auroginosa. Five clinical isolates of P. aeruginosa ...
