ResAT-Vet: Austria’s 2025 Resistance Report for clinical isolates of selected bacteria pathogenic to animals
This report presents the first Austria-wide analysis of resistance data for pathogens affecting animals, based on samples taken from clinically ill pigs and cattle. The results were assessed using clinical cut-off values, which serve as a basis for treatment decisions in veterinary practice and for assessing the treatability of bacterial infectious diseases.
Thanks to the participation of seven Austrian laboratories, samples from all federal states (excluding Vienna) were included. This enables, for the first time, a presentation and assessment of the resistance situation among bacteria pathogenic to pigs and cattle at a national level.
This report is intended to provide an important basis for the evidence-based use of antimicrobial agents in veterinary practice and to support treatment decisions, although in individual cases a bacteriological examination followed by susceptibility testing should always be sought. Furthermore, the choice of treatment should take into account the specific situation on the farm in question, including housing conditions, management factors and previous treatment experience.
