I thought the pervasive theory about how it 'spontaneously emerged in nature' incredibly suspect considering I was completing my courses in Microbio and Biochem and working extensively with bacteriophages to create anti-biotic resistant e. coli with limited success under controlled lab conditions... then I realized my university-health sciences department was heavily funded by a major hospital. And all for something that was patented by Baxter:

So I find the use of silver nano-partical therapy, oral or sub-lingual administration or atomized silver inhalation methods are acutely lacking as possible means to combat anti-biotic resistant bacteria/infections, as well as viruses and fungi.
