Textbook images show peptidoglycan as straight and ordered. The biopolymer peptidoglycan that makes up bacterial cell walls was always assumed to be highly ordered. Textbook images like the one below ...

The finding of a cytoskeleton in Bacillus subtilis bacteria eliminates a fundamental difference between bacteria and higher (eukaryotic) cells.

Scientists have produced the first high-resolution images of the structure of the bacterial cell wall, in a study that could further understanding of antimicrobial resistance.

This wall is a crucial structure for bacterial shape and division, which makes it a good target for antibiotics. Elements of it also trigger powerful immune responses against infections.

New technology has given scientists the first look ever at RNA in a live bacteria cell -- a sight that could offer new information about how the molecule moves and works.

Flagella are primarily used for cell movement and are found in prokaryotes as well as some eukaryotes. The prokaryotic flagellum spins, creating forward movement by a corkscrew shaped filament. A ...
