Targeted Bioimaging of Microencapsulated Recombinant LAB Vector Expressing Fluorescent Reporter Protein: A Non-invasive Approach for Microbial Tracking

cells, allowing us to study the spatiotemporal distribution for an extended time in the gut of two unrelated hosts, avian and murine. The present scheme involving genetic modification and chitosan encapsulation of non-commensal LAB vector demonstrates great promise as a non-invasive and intensive tool for active live tracking of gut microbes.
