The Impact

AbstractThe use of antimicrobials in the animal industry has increased the prevalence of antimicrobial resistant commensal bacteria in food products derived from animals, which could be associated with antimicrobial resistance in human pathogens. To reduce the influx of antibiotic resistant bacteria (and genes) to the human microbiota, restrictions on antimicrobials (in food animals) have been implemented in different countries. We investigated the impact of antimicrobial restriction in the frequency of antimicrobial resistant bacteria in pigs. No differences in antimicrobial resistance or antimicrobial resistance genes (richness or abundance) was found when we compared animals fed with and without antibiotics. Fitness costs of antimicrobial resistance in bacteria (in the field) seems to be overestimated.

The Impact

Abstract Background: The use of antimicrobials in the animal industry has increased the prevalence of antibiotic resistant bacteria and antimicrobial-resistance genes which can be transferred to human microbiota through the food chain or the environment. To reduce the influx of antibiotic-resistance to the human microbiota, restrictions on antimicrobials (in food animals) have been implemented in different countries. We investigated the impact of an antimicrobial restriction on the frequency of antimicrobial-resistant bacteria in pigs (PCI 1050) from an Ecuadorian farm. Results: No differences in antimicrobial resistant coliforms or antimicrobial resistance genes (richness and abundance) were found when we compared animals fed with or without antibiotics. Nevertheless, the absence of antimicrobials in pigs didn’t impact the productive performance of animals. Conclusion: Fitness costs of antimicrobial resistance in bacteria within intestinal microbiota of animals seems to be overestimated. Avoiding antimicrobials as prophylactics in pigs fed is not enough to control maintenance and spread of antimicrobial resistance.
