Some also kill fungi (fungicidal), bacterial spores (sporicidal), or viruses (virucidal). An antibacterial product acts against bacteria in some unspecified way.

They kill off the bacteria by causing the proteins to become damaged and the outer layers of the bacteria cell to rupture. The DNA material subsequently leaks out.
