Bacteria come in a surprising variety of shapes. In addition to rod-shaped representatives such as the widely known model bacterium E. coli, there are numerous curved and even spiral-shaped bacteria.

Experts divide them into Gram-positive cocci or bacilli, depending on their shape. Key characteristics of Gram-positive bacteria Gram-positive bacteria differ from Gram-negative in their structure.

Analysis of the evolution of the pathogenic bacteria that live in the nasopharynx suggests that the shape of these bacteria has changed over time, shifting from bacillus to coccus.
