Which infection is caused by a rod-shaped organism?

Understanding which infections are caused by rod-shaped bacteria helps distinguish bacterial forms from viruses and parasites. Gas gangrene is classically linked to a rod-shaped, anaerobic bacterium, Clostridium perfringens. This organism grows in damaged, low-oxygen tissue and produces gas as it multiplies, making it a textbook example of a infection caused by a rod-shaped organism. Measles is a viral illness, so it’s not caused by bacteria. Malaria is caused by a protozoan parasite, not a bacterium. Diphtheria is caused by a rod-shaped bacterium, Corynebacterium diphtheriae, but in the context of this question the standout example of a rod-forming organism causing tissue infection is gas gangrene.
