The type of bacteria that is typically round in shape is cocci. Cocci are spherical bacteria that can exist as single cells or form clusters. They play significant roles in various environments, including human health and disease, as they can be found in pathogenic forms (like Streptococcus and Staphylococcus) as well as in beneficial forms that are part of the normal flora.

Understanding the shapes of different bacteria is key in microbiology, as it can impact how they react to treatments and the way they may infect hosts. The other types listed have distinct characteristics: bacilli are rod-shaped, spirilla are spiral or corkscrew-shaped, and vibrios are comma-shaped. Each of these shapes influences the bacteria's behavior and the way they are studied in the context of health and disease.
