For obvious reasons there is a lot of interest in finding new sources for antimicrobial compounds that work against MRSA, and in finding non-drug remedies as well. There's been a small upsurge in reports of such research recently, which may be coincidence or may simply be due to the timing of certain scientific meetings.
Notably there was the report of "four or five super-active peptides" found in the blood of alligators and reported at the American Chemical Society's annual meeting a few weeks ago (first author Lancia Darville. Louisiana State University; Science News' take on the story is here), and another report at the same meeting of antimicrobial compounds in clay (authors Lynda Williams and Shelley Haydel of Arizona State University; press release here).
And just a few days ago, the journal Clinical Infectious Diseases posted ahead-of-print a study from the Netherlands on a "medical-grade honey" named Revamil that reduced skin colonization by resistant bacteria 100-fold.
That study's authors raise a red flag: that while honey has an antibacterial reputation that reaches back into prehistory, most investigations of honey as an antimicrobial have tripped up on the lack of product standardization, with batches from different areas, or even the same area at different times, showing significant variations in antibacterial activity. (Standardization of active ingredient is a long-standing problem for herbal remedies as well; regulatory authorities in Europe, where herbal preparations are more mainstream, are far ahead of the US on tackling this.)
It's important to remember that, naturally-sourced or not, antimicrobials are antimicrobials and must be handled with care, or they may invoke the sort of unintended consequences that brought us resistant organisms in the first place. For an excellent example of this, see a little-noticed paper from Irish researchers published last year in the the Journal of Antimicrobial Chemistry. That group found problems with the well-researched natural antimicrobial tea tree oil (Melaleuca alternifolia), which is commonly used in "natural" toiletries and cleaning products (and which I have in my own medicine cabinet). When tea tree oil was applied to bacterial colonies at a lower-than-lethal dose, the surviving bacteria developed resistance not only against the oil's active ingredient, but also against a range of antibiotics including vancomycin.
