  • Correlative Cryo-Fluorescence and Cryo-Scanning Electron Microscopy as a Straightforward Tool to Study Host-Pathogen Interactions

    Correlative light and electron microscopy is an imaging technique that enables identification and targeting of fluorescently tagged structures with subsequent imaging at near-to-nanometer resolution. We established a novel correlative cryo-fluorescence microscopy and cryo-scanning electron microscopy workflow, which enables imaging of the studied object of interest very close to its natural state, devoid of artifacts caused for instance by slow chemical fixation. This system was tested by investigating the interaction of the zoonotic bacterium Borrelia burgdorferi with two mammalian cell lines of neural origin in order to broaden our knowledge about the cell-association mechanisms that precedes the entry of the bacteria into the cell.

  • Imaging of Host Cell-bacteria Interactions using Correlative Microscopy under Cryo-conditions

    Pathogenic bacteria have developed intriguing strategies to establish and promote infections in their respective hosts. Most bacterial pathogens initiate infectious diseases by adhering to host cells surface. Knowledge of the interplay between the pathogenic organism and the host cells can provide fundamental new insight into the underlying mechanisms of the infectious process and therefore of the disease. Various microscopy techniques have proven to be critical tools to study these events.
