| Abstract | Foodborne bacterial infections are a major cause of gastrointestinal illness. Murine models have been widely used to interrogate bacterial pathogenesis and host response to better understand the pathogens that cause gastrointestinal disease. Humans are usually exposed to these pathogens through consumption of contaminated food products. However, most murine models of foodborne infection rely on oral gavage to deliver pathogens directly into the stomach. While expedient, the gavage procedure may lead to microabrasions in the esophagus that allow direct access of the pathogen to the blood, which can alter bacterial pathogenesis and the host response under study. In this chapter, the alternative approach of foodborne infection through the consumption of inoculated food is described using the human pathogen Listeria monocytogenes (Lm). A detailed protocol of this methodology is provided with details of assessing bacterial burden and the host immune response. Translation of these methods to other foodborne pathogens will allow a more accurate assessment of bacterial pathogenesis and host immunity in more physiologic murine models. |
