BACKGROUND: Clostridium botulinum (C. botulinum) is known for producing one of the strongest neurotoxins, namely botulinum neurotoxin (BoNT). This toxin is responsible for causing botulism, which is considered a severe neurological disease.
OBJECTIVES: This comprehensive narrative review highlights the dual nature of C. botulinum as both a serious health threat and a groundbreaking therapeutic agent. Methods: A comprehensive literature search was conducted in Google Scholar, PubMed/Medline, and Scopus (1971-2025, 2020-2025 literary focus) using keywords related to botulism pathogenesis, clinical features, and therapeutic approaches.
RESULTS: Key findings indicate that, despite advancements in botulism management and reduced mortality due to heptavalent botulinum antitoxin (HBAT) and botulism immune globulin intravenous (BIG-IV) antitoxins, diagnostic challenges and bacterial spore resistance, particularly in group I, remain persistent. On the other hand, the discovery of serotype BoNT/X with lower toxicity in vertebrates and unique capabilities has opened new horizons in the design of safer treatments.
CONCLUSIONS: C. botulinum represents a remarkable paradox in biology, an organism capable of producing one of the deadliest toxins known, yet simultaneously a cornerstone in modern therapeutic innovation. In fact, this toxin's dual nature is based on its selective targeting of BoNTs. In this regard, the systemic entry and distribution of this poison in the body - or, in other words, intoxication with it - poses a life-threatening aspect. On the other hand, the use of this bacterium's toxin for therapeutic and medicinal purposes is progressing due to its topical and controlled administration and entry into the body make it a targeted and effective therapeutic tool in the field of medicine. A better and more precise understanding of the mechanisms of action and, if necessary, future structural and engineered modifications in the toxin could lead to the emergence of a new generation of BoNTs that hold promise for the development of esthetic and therapeutic applications in medicine.
