A trained neural network model processes a 3D axial stack of darkfield microscopy images, rapidly processing the 3D optical scattering information of bacterial cells to digitally stain label-free ...

In this simplified diagram of gram staining, bacterial cells are first treated with a purple dye called crystal violet. The dye gets into the cells’ peptidoglycan layer (gray), tinting it purple.

Gram-positive bacteria are bacteria that contain a thick cell wall. During the Gram staining process — a test that experts use to view the bacteria under a microscope — they appear purple or blue.

The new biosensor promises to speed treatment of bacterial ... developed a way to measure the growth and drug susceptibility of individual bacterial cells without the use of a microscope.

Fluorescent microscopy has revolutionized the study of bacteria and helped scientists to understand various aspects of their growth, development, and pathogenesis. Bacterial cells are around 1 ...

But microscopy studies revealed that the strands were actually bacteria so large that they can be seen without the help of a microscope. ... most bacterial species' cells are about 2 micrometers ...

Here, we investigate the kinetics of individual bacterial cell death using a novel high-speed atomic force microscope optimized for imaging live cells in real time.

Even single cells have to maintain their shape: In higher organisms, the supporting structures of the cytoskeleton, which include filament networks made of the protein actin, take care of this job.
