The present study aimed to determine the susceptibility of Pseudomonas aeruginosa strains isolated from patients with nosocomial infections to standard synthetic chemical antibiotics and organic ethanoic acids derived from local produce. The minimum inhibitory concentrations (MIC) of the standard synthetic antibiotics determined from standard e-test results and antibiotic sensitivity tests showed many multidrug-resistant strains among the isolates. We compared the susceptibility of these strains to organic ethanoic acids derived from different sources using standard microbiological assays. All strains of P. aeruginosa isolated from the patients were susceptible to the organic ethanoic acids with a satisfactory MIC and minimum bactericidal concentrations. Therefore, organic ethanoic acids were more effective against P. aeruginosa than standard synthetic antibiotics.
