Antimicrobial and antibiofilm activities of culture filtrates from Lactiplantibacillus plantarum isolated from traditional dairy products in Menoufia, Egypt.

ABSTRACT:

Background

The global rise in multidrug-resistant (MDR) bacterial infections poses a serious threat to public health, largely driven by the overuse and misuse of antibiotics. In this context, lactic acid bacteria (LAB) and their postbiotic metabolites have attracted attention for their natural antimicrobial and antibiofilm activities. This study aimed to evaluate the effects of LAB-derived postbiotics against four clinically relevant pathogens: Escherichia coli ATCC 25,922, Staphylococcus aureus ATCC 6538, Pseudomonas aeruginosa ATCC 9027, and a clinical isolate of Klebsiella pneumoniae.

Results

LAB strains were isolated from traditional fermented dairy products in Menoufia, Egypt, including Kareish cheese, Rayeb milk, and local yoghurt, using MRS agar medium. Among twelve a
