Summary
Antibiotic use in animals contributes to the rise of resistant bacteria, posing risks to human health and clinical infection management. This highlights the urgent need to address antibiotic resistance in food animals.
Area of Science:
- Veterinary Medicine
- Microbiology
- Public Health
Background:
- Antibacterial compounds are increasingly used in animal husbandry and fish farming.
- Antibiotic exposure in animals mirrors human medicine, leading to the emergence of resistant bacteria.
- Concerns exist regarding the impact of animal antibiotic use on human health.
Purpose of the Study:
- To discuss the implications of antibiotic use in animals for human health.
- To analyze the emergence of antibiotic resistance genes and multiresistant pathogens in food animals.
- To inform the management of clinical infections in humans.
Main Methods:
- Literature review on antibiotic use in animal agriculture.
- Analysis of evidence linking animal antibiotic exposure to resistance gene emergence.
- Discussion of pathogenicity of emerging multiresistant pathogens.
Main Results:
- Antibiotic use in food animals directly contributes to the development of antibiotic resistance.
- Emergence of novel resistance genes and highly pathogenic multiresistant bacteria in food animal populations.
- Potential for zoonotic transmission of resistant pathogens.
Conclusions:
- Antibiotic resistance in animals is a significant public health concern.
- Prudent use of antibiotics in animal agriculture is crucial.
- Further research is needed to mitigate the spread of antibiotic resistance from animals to humans.
