What type of bacteria are rod-shaped and spore-producing?

Bacilli refer to a specific classification of bacteria characterized by their rod shape and ability to form spores. This genus is known for its resilience and can survive in harsh environments due to spore formation, which is a protective mechanism allowing them to endure unfavorable conditions.

Cocci are spherical-shaped bacteria, while spirilla are spiral-shaped, and vibrios are comma-shaped. None of these classifications involve rod shapes or spore production, further emphasizing why bacilli is the correct choice in this context. Understanding these different bacterial shapes can be important in various fields, including microbiology and health sciences, as they can influence how infections are treated and managed.
