The use of cultured mammalian cells, whether immortalized cell lines or primary cells, is a well-known technique used as a substitute or prescreen for in vivo virulence potential of bacterial pathogens. This technique is also a way to examine host-pathogen interactions in a less complex environment compared to that found in whole animals. To this end, macrophage infection assays have become a key technique for studying the molecular mechanisms by which bacteria interact with the host. Herein, this chapter describes both how to produce macrophages from mouse bone marrow and the subsequent infection assays.
