Abstract
Pseudomonas aeruginosa causes many infections worldwide. Multidrug-resistant bacteria are mostly watched in hospital-acquired infections and are linked with high mortality rates. This study aims to find a possible cure for P. aeruginosa by using an additive and synergistic combination of drugs. The Carbapenem-resistant P. aeruginosa were isolated and identified by using clinical and laboratory standards institute protocols and their antibiotic susceptibility testing was performed by using disc and well diffusion method. In computational analysis, all of the ligands and proteins were selected and docking was done using PYRX. Hundred samples were taken of isolated Gram-negative bacteria of which 25% were P. aeruginosa. Additive combinations (meropenem [MPM] + tobramycin [TOB] was 100% sensitive and imipenem + TOB was also 100% sensitive) and synergistic combinations (MPM + ciprofloxacin were 90% sensitive and amikacin and imipenem) were 100% sensitive according to CLSI protocol. In computational analysis, TOB gave the highest binding energy of −11.4, whereas MPM shows a binding energy of −9.3. In conclusion, Additive and synergistic combination of drugs showed good antibacterial activity against Pseudomonas aeruginosa. Hence it can be used as a good treatment option for P. aeruginosa.
期刊介绍:
Open Chemistry is a peer-reviewed, open access journal that publishes original research, reviews and short communications in the fields of chemistry in an ongoing way. The central goal is to provide a hub for researchers working across all subjects to present their discoveries, and to be a forum for the discussion of the important issues in the field. The journal is the premier source for cutting edge research in fundamental chemistry and it provides high quality peer review services for its authors across the world. Moreover, it allows for libraries everywhere to avoid subscribing to multiple local publications, and to receive instead all the necessary chemistry research from a single source available to the entire scientific community.
