CLOSTRIDIUM DIFFICILE : CHLORINE DIOXIDE

Used for years in water purification and in swimming pools, chlorine dioxide is a more potent and much more selective oxidiser than bleach (sodium hypochlorite), so therefore it is much less affected by organic contamination. 

For instance, 10 parts of bleach chlorine are destroyed by 1 part of ammonia. In contrast, chlorine dioxide is unaffected by ammonia, and so is potentially an effective weapon in the superbug war. 

However, there is a problem. 

Chlorine dioxide is a very reactive chemical, an electron scavenger, and so is usually generated by special equipment when and where it is required.
