Although amyloid aggregation has been generally associated with protein misfolding and neurodegenerative diseases in mammals, bacteria and other organisms have harnessed amyloidogenesis to perform diverse biological processes. These functional amyloids, some of them secreted and others intracellular, require that the producing cells keep aggregation under control in the cytoplasm upon protein translation, preventing their inherent toxicity. Thus, it is highly relevant to understand how intracellular amyloid formation occurs and is regulated, its metabolic consequences, and the formation dynamics and fate of the amyloid inclusions upon cell division. This chapter describes methods leveraging fluorescence microscopy and fixed- or live-cell imaging to monitor intracellular amyloid formation in bacterial cells.
