Infectious pododermatitis is a common condition in sheep with initial lameness, with a variation in severeness over time. Independently on aetiology, the administration of antibiotics has proven to be ineffective, the disease often being exacerbated in a short time, the bacteria being refractory to antimicrobials. The use of antibiotics is common in sheep for disease treatment, health protection and as growth promoters. The main antibiotics used in farmed animals are tetracyclines, penicillin, quinolones and cephalosporins. According to the latest studies, E. coli, an ubiquitous bacterium often isolated from pododermatitis lesions, is unresponsive to all these antibiotics. Studies on the antibiotic resistance of the main pathogens of necrobacillary pododermatitis, Dichelobacter nodosus and Fusobacterium necrophorum, are not found in the literature, but the ineffectiveness of antibiotics on these bacteria directs towards a possible antibiotic resistance. Currently, multiple health organisations have identified proliferation of antimicrobial resistance as a global crisis. The decline in bacterial susceptibility to common antibiotics calls for global efforts on the rational use of antibiotics in veterinary medicine as a response to the spread of antimicrobial resistance.
