Our Scientific Discoveries
We prioritize closing critical knowledge gaps regarding the public health impact of antibiotic overuse and misuse in people and animals. In particular, we are focused on understanding antibiotic use in food-animal production so that this issue is no longer marginalized, and all the major drivers of antibiotic resistance are properly addressed. Below are some of our latest scientific discoveries.
E. coli Strain from Retail Poultry May Cause Urinary Tract Infections in People
New findings published in the American Society for Microbiology’s open access journal mBio revel that a strain of Escherichia coli (E. coli) found in retail chicken and turkey products may cause a wide range of infections in people. Researchers knew that E. coli could be passed from person-to-person in the community and in hospitals. However, this study, “Escherichia coli ST131-H22 as a Foodborne Uropathogen,” provides evidence that the E. coli lurking in fresh poultry products can be passed to people, leading to bladder infections and other serious conditions.

Review: Food-Animal Production and the Spread of Antibiotic Resistance: The Role of Ecology
Frontiers in Ecology and the Environment published a review, "Food-animal production and the spread of antibiotic resistance: the role of ecology," that outlines how tracking bacterial movement between humans and animals is key to understanding antibiotic resistance. It examines how genomic data are elucidating, in unprecedented detail, the pathways by which antibiotic-resistant bacteria move between food animals and humans. Applying basic ecological principles can help organize this new knowledge to better monitor, understand and manage the spread of antibiotic resistance. Read the review and press release.
Livestock Associated MRSA Causes Serious Blood Infections in People
Most Infections Occurred in People Who Had No Contact with Farm Animals
A study published in Clinical Infectious Diseases found that livestock-associated Methicillin-resistant Staphylococcus aureus (LA-MRSA) can cause serious bloodstream infections in people. Researchers studied blood stream infections caused by all strains of MRSA in Denmark from 2010 to 2014 and found that blood infections from LA-MRSA were on the rise, peaking in 2014 and accounting for 16 percent of all MRSA bloodstream infections.

Research Suggests Superbug MRSA May Be Spreading Through Contaminated Poultry
Study suggests people in urban areas with no exposure to livestock are becoming infected with poultry-associated MRSA via meat
New findings published in the journal Clinical Infectious Diseases suggest a novel form of the dangerous superbug Methicillin-Resistant Staphylococcus aureus (MRSA) can spread to humans through consumption or handling of contaminated poultry. The research shows that poultry may be a source of human exposure to MRSA, a superbug which can cause serious infections and even death. Read the study and the press release for more details.
Research Suggests Retail Meat is a Potential Vehicle for Disease-Causing Klebsiella
Study Is First To Link Klebsiella-Contaminated Food to Urinary and Blood Infections
Findings show that contaminated meat sold in grocery stories may be an important source of human exposure to Klebsiella pneumoniae. The research is the first to link Klebsiella contaminated food to urinary and blood infections. Read the study and press release for more details.
Multi-center Study Points Towards New Strategies for Stopping the Spread of Staph and MRSA
Study suggests that bacteria of the human nose are not genetically predetermined and that some nasal bacteria may protect against MRSA
Findings published in the AAAS journal Science Advances demonstrate that nasal microbiota is not fixed by host genetics and opens the possibility that nasal microbiota may be manipulated to prevent or eliminate S. aureus colonization. Read the study and press release for more details.
