Junjia He's doctoral research focuses on the epidemiology of antimicrobial resistance (AMR) in companion animals within the One Health framework. Her project investigates critical transmission pathways and risk factors associated with resistant bacteria in pets and their environments.

The research encompasses multiple interconnected components investigating AMR prevalence and risk factors in commercial raw pet food, biosecurity implementation gaps in companion animal veterinary practices, and the development of comprehensive evaluation systems for clinical settings. Through this work, she aims to identify key sources and transmission routes of antimicrobial-resistant bacteria between companion animals, their food sources, veterinary environments, and potentially their human owners. A significant portion of her research has been conducted at Sciensano, where she has gained extensive laboratory experience that complement her epidemiological research approach.

The project contributes essential evidence for developing targeted AMR control strategies in companion animal medicine while strengthening understanding of human-animal-environment interfaces in resistance transmission. This research addresses critical knowledge gaps in companion animal AMR epidemiology and provides practical tools for veterinary practitioners to implement effective biosecurity measures.
