Antimicrobial resistance (AMR): What measures should we use?
MetadataShow full item record
AMR is an important issue for human and animal health and welfare. There are often blanket calls for “….increased surveillance of AMR” but what does this mean? • What questions are we asking, should we be asking, and how do we do so? Existing global AMR surveillance2 has various limitations. Of greatest importance to this study are that they are often: • Based on clinical samples (bias), and • Lack standardisation of methods Locally, SAC C VS routinely uses disk diffusion to measure AMR of E. coli in non-clinical faecal samples from cattle and sheep. Bacterial densities vary hugely and this affects some types of measurement at the sample level3. We used alternative tests in parallel to the routine disk diffusion. We describe the results for one antibiotic against E..coli and demonstrate that the perceived level of resistance is greatly dependent on the method chosen.
