Inhibitory effect of zinc sulfate on clinical isolates of Pseudomonas aeruginosa and Acinetobacter baumannii

Abstract

This objective of the study was to determine the inhibitory effect of zinc sulfate against the clinical isolates of Pseudomonas aeruginosa and Acinetobacter baumannii. The inhibitory effect of zinc sulfate was determined against the 120 clinical isolates (60 isolates of P. aeruginosa and 60 isolates of A. baumannii) by agar dilution method. The findings indicate that zinc has an inhibitory effect on the clinical isolates of P. aeruginosa and A. baumannii at a concentration ranging from 0.25to 1mg/ml of zinc sulfate by agar dilution method.
