New/Old Approach to Antibiotic-Resistant Bacteria

Infections Worry Military Doctors" is a headline in the
Washington Post.  It reflects a serious concern often noted
here at ScienceBlogs.  I read it and worried, again.
 But perhaps there is hope: maggots.  From
News@Nature.com:

eat up resistant bacteria


Creepy
crawlies are the latest weapon in the anti-MRSA arsenal.

MRSA has a new adversary — the maggot. Researchers in
Manchester, UK, have just won a grant to compare maggots with other
more hi-tech treatments for people with diabetes who suffer from
infected feet...



...A small initial trial, published this February, showed considerable
success1. 'Larval therapy' (the polite term for maggot treatment) was
excellent for shifting MRSA infected tissue: in 12 out of 13 patients,
their wounds healed after between three and five applications of
maggots, each lasting four to five days. "It's primitive but
effective," says Boulton...



To top it off, they have a picture of a wound that is being treated
with maggots.  I can't bring myself to post the photo here,
but for those with a morbid inclination, it is there.



We can hope that it might be possible to figure out what the maggots
are doing that is effective against href="http://en.wikipedia.org/wiki/MRSA" rel="tag">MRSA,
and reproduce it in the form of a nice, clean, sterile, patentable
liquid.

I would think that they are just eating the bacteria, just because the MRSA is resistant to antibiotics does not mean they are not yummy food for a maggot.

Why make the liquid you hope for patentable?
