What does clostridial mean?
"Clostridial" is an adjective used in medicine, veterinary science, and microbiology to describe anything relating to, caused by, or characteristic of Clostridium, a genus of anaerobic, spore-forming bacteria. These organisms are notable for thriving where oxygen is absent, such as deep puncture wounds, soil, and the intestinal tract. The adjective appears most often in phrases like "clostridial infection," "clostridial disease," and "clostridial myonecrosis" (gas gangrene), and it is central to discussions of illnesses such as tetanus and botulism, which certain Clostridium species cause through potent toxins. In livestock farming, "clostridial vaccines" are a routine part of animal health programmes. Because it is a specialist scientific term, "clostridial" seldom occurs outside clinical, laboratory, or agricultural writing, though its association with some of the most feared bacterial toxins gives it considerable weight when it does appear.
adjectiveRelating to, caused by, or characteristic of bacteria of the genus Clostridium, a group of anaerobic, spore-forming rod-shaped bacteria.
- Relating to or caused by bacteria of the genus Clostridium.
"The veterinarian diagnosed the cattle with clostridial disease after several animals fell ill suddenly."
"Clostridial infections can develop rapidly in deep wounds deprived of oxygen."
"Farmers routinely vaccinate livestock against the major clostridial diseases."
The genus behind the word includes the bacteria that cause tetanus, botulism, and gas gangrene — yet most healthy animals carry harmless clostridia in their gut every day.

Etymology of clostridial
The word derives from Clostridium, a genus name coined in the late 19th century by Polish microbiologist Adam Prażmowski. The name comes from the Greek "kloster" (κλωστήρ), meaning a spindle or something twisted, chosen because these rod-shaped bacteria sometimes swell into spindle-like forms at the site of spore formation. The English adjective "clostridial" was formed directly from the genus name using the adjectival suffix "-al."
