KC Jeong Lab
Led by Kwangcheol Casey Jeong · Animal Sciences
What we study
The lab studies how bacteria like E. coli and Legionella cause disease, focusing on their survival in hosts and antimicrobial resistance. They develop new treatments using nanoparticles and microparticles.

Current projects
Identify and understand bacterial effector proteins that cause disease in hosts
Researching proteins that help bacteria infect and survive inside host cells.
Whole genomic DNA analysis to identify genes that are required for survival and persistence in hosts and environments
Studying bacterial genes essential for survival in hosts and different environments.

Determine host factors that modulate the survival of pathogens in infection
Exploring how host factors affect how pathogens survive and persist in infections.
Investigating the Antimicrobial Resistance Profile of Salmonella Isolated from Dairy Cows
The lab checks how common a food‑borne bacteria from dairy cows is resistant to antibiotics. The student collected bacterial samples, tested them against a panel of drugs, and identified which antibiotics the strains were less sensitive to.
