Abstract—We established and validated a non-pathogenic bacteria to express a far red fluorescence protein mKate2 for in vivo studies in mice. Using the fluorescence reflectance imaging (FRI) system, the bacteria expressing mKate2 was tested non-invasively and in real-time in different mouse body compartments, including subcutaneous, abdominal, and gastrointestinal tract. Our results suggested that bacteria colonization could be clearly visible and successfully monitored over time in live animals. This method could be a prospective approach for further studying of either pathogenic or non-pathogenic bacterial infection, antibiotic therapy or bacteria as drug-gene delivery for tumor therapy in small animal model such as mice.
