What is the shape of cocci bacteria?

Cocci bacteria are characterized by their round or spherical shape. This distinct morphology allows them to be easily identified under the microscope, contributing to their classification in microbiology. The spherical structure of cocci can lead to various arrangements when they divide; for instance, they can appear in chains (known as streptococci), clusters (known as staphylococci), or in pairs (known as diplococci). Understanding the shape of cocci is essential in dental nursing and microbiology, as it aids in the identification and treatment of infections caused by these bacteria.
