Which term describes round-shaped bacteria?

Explanation:
Round-shaped bacteria are called cocci. Cocci are spherical and can appear alone or in various arrangements such as pairs, chains, or clusters. The other terms describe different shapes: bacilli are rod-shaped, spirilla are spiral, and vibrios are curved, comma-shaped rods. Recognizing cocci helps with quick visual identification under the microscope and supports initial differentiation in lab work.
