Electron microscopy techniques to study bacterial adhesion.

Since its introduction 70 years ago electron microscopy has become an invaluable tool for microbiology and the study of bacterial interaction. Technological development over the past decades has enabled researchers to resolve smaller and smaller details in bacterial samples, while new preparation techniques like cryo preparation now allow to investigate bacteria even closer to their natural state. In this chapter we give a brief overview of electron microscopy techniques suitable for the investigation of bacterial adhesion at molecular as well as cellular level and a short outlook on future technologies relevant to the field.
