Abstract
This study investigates the antimicrobial properties of leukocyte- and platelet-rich fibrin (L-PRF) against Enterococcus faecalis (ATCC 29212), Pseudomonas aeruginosa (ATCC 27853), and Candida albicans (ATCC 90028). Infections can hinder wound healing posing challenges. L-PRF's potential for regeneration and antimicrobial action has been studied. Considering the increasing concern about antibiotic resistance, assessing the antimicrobial properties of L-PRF provides valuable insights into its potential as a therapeutic agent in postoperative infections. Twenty volunteers were enrolled in the study, following ethical guidelines, and obtaining informed consent. Blood samples were collected and L-PRF was prepared. Microbial suspensions were prepared, and susceptibility testing was performed using the Kirby-Bauer agar diffusion method. The study revealed significant heterogeneity in the susceptibility to L-PRF. All L-PRF membrane samples exhibited antimicrobial activity against P. aeruginosa, with inhibition zones of 13 mm ± 3.85 SD. Enterococcus faecalis displayed inhibition diameter of 7.25 mm ± 5.15 SD. Candida albicans susceptibility to L-PRF varied among samples, with both inhibitory and non-inhibitory results. Results showed varying degrees of antimicrobial activity, particularly against P. aeruginosa, and highlight the complexity of the L-PRF-microorganism interaction. Further investigations are needed to elucidate the clinical implications and optimize the use of L-PRF.
