Organization profile

Microorganisms – bacteria, viruses, fungi – reside in diverse and heavily populated communities on the skin and mucous membranes of animals, including humans. Wherever they are located on or in the body, these microbes maintain intimate and often mutually beneficial relationships between themselves and their animal hosts. The vast community of bacteria residing in the digestive tract can undergo significant changes over the lifespan of food animals and people, and these shifts in population can affect the host’s overall health and development. Drugs, particularly antimicrobial agents, can contribute to these bacterial community shifts. Antimicrobial drugs can promote the growth of food animals, but their widespread use is contributing to increased microbial drug resistance.  Similarly, excessive antibiotic use by people can fight disease, but can also lead to the emergence of drug-resistant microorganisms.   Through genomic analyses and mathematical modeling, faculty in the Microbiome/Antibiotic Resistance research cluster are characterizing the intestinal bacteria, viruses and the small DNA molecules that transfer antibiotic resistance among bacteria in food animals.  They seek to discover how changes in the gut microbial community affect animal growth and well-being.  Their research will contribute to the development of antibiotic alternatives, such as new probiotics, to enhance animal growth and reduce the incidence of antimicrobial drug resistance.

UN Sustainable Development Goals

In 2015, UN member states agreed to 17 global Sustainable Development Goals (SDGs) to end poverty, protect the planet and ensure prosperity for all. Our work contributes towards the following SDG(s):

  • SDG 2 - Zero Hunger
  • SDG 3 - Good Health and Well-being
  • SDG 7 - Affordable and Clean Energy
  • SDG 11 - Sustainable Cities and Communities
  • SDG 14 - Life Below Water
  • SDG 15 - Life on Land
  • SDG 17 - Partnerships for the Goals
