The bacterial flagellum is an appendage structure that provides a means for motility to promote survival in fluctuating environments. For the intracellular pathogen Salmonella enterica serovar Typhimurium to survive within macrophages, flagellar gene expression must be tightly regulated, and thus, is controlled at multiple levels, including DNA recombination, transcription, post-transcription, protein synthesis, and assembly within host cells. To understand the contribution of flagella to Salmonella pathogenesis within the host, it is critical to detect flagella production within macrophages via microscopy. In this paper, we describe two methods for detecting bacterial flagella by microscopy both in vitro and in vivo infection models.
