Investigation of drug targets for pseudomonas aeruginosa
The increased prevalence of multi-drug resistant Pseudomonas aeruginosa and inadequacy of conventional antimicrobial solutions have been a major concern worldwide. Hence, there is an urgent need of identifying novel drug targets. In this study, artificial sputum medium(ASM) and M9 supplemented media...
