Which of the following describes bacilli?

Bacilli are best described as rod-shaped bacteria. This distinct shape is a key characteristic that sets bacilli apart from other types of bacteria, such as cocci, which are spherical and often found in pairs, and spirilla or vibrios which have curved shapes. The rod shape of bacilli allows them to be identified under a microscope and is essential in microbiology for categorizing bacteria based on their morphology. Understanding bacterial shapes is crucial for identification and treatment purposes in nail technology and other health-related fields, as different types of bacteria can have varied effects on skin and nail health.
