Complexities of Antimicrobial Resistance in Farm Animals and Public Health
The epidemiology of antimicrobial resistance is multifaceted, involving various sectors such as aquaculture, soil, wildlife, human-animal interfaces, and more. The case study on ceftiofur resistance in chickens highlights the impact of antibiotic use on resistance levels in both animals and humans. This compilation sheds light on the intricate interplay between agriculture, animal health, and the spread of antimicrobial resistance, posing significant challenges to public health.
