Antibiotic resistance is a very real threat to modern standards of human and veterinary healthcare.1 This is a one health problem – we share many antimicrobials, our bacteria are closely related, and the resistance genes are the same. All healthcare professionals therefore share a responsibility for antimicrobial stewardship to preserve the efficacy of these drugs for the future.

Monitoring resistance is a key part of stewardship. The paper by Teichmann-Knorrn and others2 summarised on p 21 of this week’s issue of Vet Record is therefore welcome and such studies are to be encouraged. Epidemiological data identifies resistance trends, which can inform local and national antimicrobial stewardship policies. This isn’t just an academic exercise – awareness of national and local resistance patterns is directly relevant to clinical practice. However, we need to use this data wisely – for example, taken literally the abstract suggests that the critically important antimicrobials imipenem, nitrofurantoin, gentamicin and amoxicillin-clavulanate are the most appropriate drugs for feline urinary tract infections. …
