What shape do cocci bacteria have?

Cocci bacteria are characterized by their round shape. This spherical configuration is a distinctive feature that sets them apart from other shapes of bacteria, such as bacilli, which are rod-shaped, and spirilla, which have a spiral configuration. The term "coccus" itself is derived from the Greek word for "berry," reflecting this round appearance. This shape plays a role in identifying and classifying bacteria in microbiology, aiding in the diagnosis of various bacterial infections. Understanding the morphology of bacteria, including cocci, is fundamental for microbiologists as it helps in determining the appropriate treatment methods based on the type of bacteria involved.
