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.
