Cell-free supernatants from cultures of lactic acid bacteria isolated from fermented grape as biocontrol againstSalmonellaTyphi andSalmonellaTyphimurium virulence via autoinducer-2 and biofilm interference

Salmonella Typhi and Salmonella Typhimurium are the causative pathogens of salmonellosis, and they are mostly found in animal source foods (ASF). The inappropriate use of antibiotics enhances the possibility for the emergence of antibiotic resistance in pathogens and antibiotic residue in ASF. One promising alternative to antibiotics in animal farming is the use of lactic acid bacteria (LAB).The present study was carried out the cells and/or the...
