Which anaerobic, Gram-positive rod produces terminal spores resembling tennis rackets?

The identification of the anaerobic, Gram-positive rod that produces terminal spores resembling tennis rackets is accurately attributed to Clostridium tetani. This bacterium is known for its characteristic morphology, particularly the distinctive shape of its spores, which can be observed microscopically. The spores form at the ends of the rod-shaped cells, creating a structure that visually resembles a tennis racket or drumstick, a defining feature that aids in its identification in a laboratory setting.

Clostridium tetani is the causative agent of tetanus, a serious nervous system condition. Its unique spore formation is a survival mechanism that allows the bacteria to withstand adverse environmental conditions. When introduced into a conducive environment, under anaerobic conditions, these spores can germinate and lead to infection.

In contrast, while the other species listed—Clostridium difficile, Clostridium ramosum, and Clostridium botulinum—are also anaerobic, Gram-positive rods, they do not exhibit the same terminal spore morphology as Clostridium tetani. Clostridium difficile is primarily associated with antibiotic-associated diarrhea and colitis and forms spores that are not terminally located. Clostridium ramosum is less commonly discussed in clinical settings and has a different clinical
