Perhaps it could be used prophylactically,
Both MSSA and MRSA are hospital acquired
No way after toxicity testing. This needs to be used, if possible, very judiciously, or else we'll promote antibacterial resistance to it.

Back in August 2009 I had not been near a hospital in about a decade. I caught a case of MRSA in my armpit and ended up at Dewitt Army Hospital in serious condition for four days.
The doctors told me MRSA is now everywhere and they think close to 50% of the population have it on their bodies. It just takes the right conditions, including the host being ill and their defenses being down for the infection to attack.
