Clostridium tetani
Benzododecinium bromide is effective against gram-positive microbes. In lower concentrations, its activity against conditionally gram-negative microorganisms (such as "Proteus", "Pseudomonas", "Clostridium tetani" etc.) is uncertain. It is not effective against "Mycobacterium tuberculosis" and bacterial spores. Longer expositions may inactivate some viruses.
