Here, we present a protocol for microinjection of bacteria into mouse small intestinal organoids that recapitulates the natural route of infection of intestinal epithelial cells from the intestinal lumen. We describe steps for visualizing bacteria-cell interactions by live imaging of infected organoids using light sheet microscopy. We then detail procedures for generating doxycycline-inducible expression of mutant proteins in organoids to study essential gene functions. The different techniques described in this protocol can be used independently as required. For complete details on the use and execution of this protocol, please refer to Kim et al. (2021).1.
