Antimicrobial resistance (AMR) represents a major global threat to both human and animal health. Within the One Health framework, farm and wild animals serve as critical reservoirs of resistant bacteria and resistance genes, which can disseminate through food, water, and the environment. The excessive and inappropriate use of antibiotics in veterinary medicine exerts selection pressure that fosters the emergence and spread of antimicrobial resistance. Current mitigation strategies aim to reduce antibiotic consumption and promote prudent use through hygiene measures, vaccination, individualised therapy, pharmacokinetic-pharmacodynamic (PK/PD) dosing optimisation, and comprehensive AMR monitoring. European legislation (EU Regulations 2019/4 and 2019/6) provides stringent guidelines on antibiotic prescription, usage, and residue limits. In this context, antibiotic combination therapy represents a promising approach to enhance antimicrobial efficacy, broaden the antibacterial spectrum, and suppress the emergence of resistance by targeting multiple bacterial pathways simultaneously. In addition to developing new drugs, renewed focus on reviving older antimicrobial molecules – supported by updated PK/PD data and optimised dosing – could provide an effective alternative in combating multidrug-resistant pathogens.
