Which term describes bacteria that have a rod shape?

The term that describes bacteria with a rod shape is "Bacillus." Bacteria are classified into different shapes, and the shape can indicate certain characteristics about the bacteria. Bacilli are elongated and cylindrical, resembling rods, which distinguishes them from other bacterial shapes.

For context, "Coccus" refers to bacteria that are spherical or round in shape. "Spirillus" describes bacteria that are spiral or corkscrew-shaped, while "Vibrio" denotes bacteria that are comma-shaped. Understanding these classifications is essential, as the shape of bacteria can influence their behavior, habitat, and how they interact with their environment and hosts.
