The human immune system produces antibacterial peptides and proteins like lactoferrin (LF). This work addresses the hypothesis that bovine lactoferrin (bLF) and its derivative peptides bLactoferricin17-30, bD-Lactoferricin17-30, bLactoferrampin265-284, bD-Lactoferrampin265-284 and bLF-chimera have antimicrobial activity on planktonic cells and pre-formed biofilms of <jats:italic>S. enterica<\/jats:italic>. Planktonic <jats:italic>Salmonella enterica<\/jats:italic> ATCC 14028 were treated with bLF and bLF-peptides for two hours, and bacterial viability was determined by counting colony-forming units\/ml. In addition, <jats:italic>S. enterica<\/jats:italic> biofilms were pre-formed or established on an abiotic surface, and viability or disruption was assessed in the presence of bLF and bLF-peptides by counting colony-forming units\/ml or using the live\/dead viability kit. We observed that bLF and bLF-peptides were bactericidal against planktonic <jats:italic>S. enterica<\/jats:italic>, killing more than 80% of cultures after two hours of treatment. The bactericidal effect was concentration and time-dependent. In addition, bLF, bLFampin165-284, and bLF-chimera showed an anti-biofilm effect against <jats:italic>Salmonella<\/jats:italic> biofilms pre-formed during 8 and 12 hours on the abiotic surface, disorganizing more than 50% of the biofilms after 4 or 6 hours of treatment. We conclude that bLF and its peptides show antimicrobial activity against planktonic cells and pre-formed biofilms of <jats:italic>S. enterica<\/jats:italic> on abiotic surfaces and could potentially be a therapeutic solution to combat <jats:italic>Salmonella<\/jats:italic> infections.<\/jats:p>","DOI":"10.1017\/s0022029925100897","type":"journal-article","created":{"date-parts":[[2025,8,18]],"date-time":"2025-08-18T08:28:06Z","timestamp":1755505686000},"page":"89-97","source":"Crossref","is-referenced-by-count":1,"title":["Effect
