One Health Topics

The Purdue University College of Veterinary Medicine is deeply committed to the One Health initiative, recognizing the interdependent nature of human, animal, and environmental health. Our main areas of focus within this initiative are Antimicrobial Resistance, Comparative Oncology, Environmental Health, and Zoonoses.

Antimicrobial Resistance

Antimicrobial resistance (AMR) occurs when microorganisms such as bacteria, viruses, fungi, and parasites change in ways that render the medications used to cure the infections they cause ineffective.

  • Why it matters: With rising AMR, common infections could once again become untreatable, posing a grave threat to both human and animal health.
  • Our role: We strive to better understand the mechanisms of resistance, promote responsible antimicrobial use, and develop alternatives to traditional antibiotics.

Comparative Oncology

Comparative oncology studies cancers in both humans and animals to find similarities and differences. This approach can help in understanding the disease better and in developing treatments.

  • Why it matters: Many animals, like dogs, develop cancers naturally, much like humans. Studying these can offer insights into human cancers and lead to mutual benefits in treatment discoveries.
  • Our role: Our research seeks to unlock the secrets of cancer across species, aiding in the development of novel treatments and therapies for both animals and humans.

Environmental Health

Environmental health deals with the physical, chemical, and biological factors external to a person, and all the related factors that can potentially affect health.

  • Why it matters: As our environment changes, it can lead to health issues in both animals and humans. Contaminated water, poor air quality, and toxic exposures can lead to a myriad of diseases.
  • Our role: We study how environmental factors influence health, disease outbreaks, and the overall well-being of animals and people. We also work to find solutions to mitigate environmental health risks.

Zoonoses are diseases that can spread between animals and humans. These can be caused by bacteria, viruses, parasites, and fungi.

  • Why it matters: Many of the major disease outbreaks in recent history, like COVID-19, have been zoonotic in origin. It's crucial to understand these diseases to prevent future pandemics.
  • Our role: We work on detecting, preventing, and treating zoonotic diseases, ensuring a safer future for both animals and people.
