Abstract
AbstractAntimicrobial resistance in bacteria causes significant morbidity worldwide. The development and acquisition of resistance to antibiotics is believed to primarily develop under the selective pressure of widespread antibiotic use in humans, however antimicrobial usage in livestock has been proposed as additional, if not principal, driver of antibiotic resistance. In this work, we correlate recent data from the European Union on antibiotic resistance rates with data on antibiotic usage in the primary care and hospital sector and data on veterinary antimicrobial consumption across the individual member states. We quantify the strength of these different potential drivers of antimicrobial resistance in order to compare their biological importance. We found that the correlation between antibiotic use in the hospital sector and antibiotic resistance rates is significantly higher than the correlation between resistance rates and any of the other two predictors. This suggests increased antibiotic use in hospitals as the main driver of the development of antibiotic resistances and necessitates further research on and a re-evaluation of the risks associated with antibiotic use in human and veterinary medicine.
