IN-VITRO ANTIBACTERIAL ACTIVITY OF LACTOBACILLI METABOLITES LOADED HYDROGEL FORMULATIONS AGAINST PSEUDOMONAS AERUGINOSA
Objective: Pseudomonas aeruginosa is an opportunistic pathogen that may cause serious infections, ranging from localized skin infections to life-threatening systemic diseases. It is one of the resistant bacteria which lead to failure in the treatment. New treatment strategies are urgently needed for the treatment of infections caused by resistant bacteria. Researchers are interested in Lactobacillus species because of their antimicrobial effective metabolites. The aim of this study was comparing the antibacterial activity of lactobacilli metabolites loaded chitosan and Pluronic F127 hydrogel formulations.
Methods: Metabolites loaded hydrogel formulations were prepared by adding 20 µl of supernatant into the polymer solutions. The antimicrobial activities of two hydrogel formulations were investigated against P. aeruginosa using Agar Spot Method. Metabolites loaded chitosan hydrogel formulations were found to be effective against P. aeruginosa.
Results: No antibacterial activity was observed for metabolites loaded Pluronic F127 hydrogel formulations. When we compare these two hydrogel formulations, we observed that hydrogel formulation prepared by using chitosan released effective metabolites but Pluronic F127 hydrogel formulation couldn’t release antibacterial effective metabolites.
Conclusion: The antibacterial effect of metabolites loaded chitosan hydrogel formulation suggests that this formulation could be used as an alternative treatment option in P. aeruginosa skin infections. However, further investigations are needed to develop a pharmaceutical product.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
