Subject and Verb
The healing power of maggots is not new. Human beings have discovered it several
times. The Maya
are said to have used
maggots for therapeutic purposes a thousand years ago. As early as the
sixteenth century, European
doctors noticed
that soldiers with maggot-infested wounds healed well. More recently, doctors have realized that maggots can be cheaper and more
effective than drugs in some respects, and these squirming
larvae have, at
times, enjoyed a quiet medical renaissance. The problem may have more to do with the weak stomachs of those
using them than with good science. The modern heyday of maggot therapy began during World War I, when an American
doctor named William Baer was shocked to notice that two soldiers who had
lain on a battlefield for a week while their abdominal wounds became infested with thousands of maggots,
had recovered better than wounded men treated in the military hospital. After
the war, Baer proved to the medical
establishment that maggots
could cure some of
the toughest infections.
In the 1930s hundreds of hospitals used maggot therapy. Maggot therapy requires the right kind of larvae. Only the maggots of blowflies (a
family that includes common bluebottles and greenbottles) will do the job; they devour dead tissue, whether
in an open wound or in a corpse. Some other maggots, on the other hand, such as those of the
screw-worm eat live
tissue. They must
be avoided. When blowfly eggs hatch in a patient’s wound,
the maggots eat the dead flesh where
gangrene-causing bacteria thrive. They also excrete
compounds that are lethal to bacteria they don’t happen to swallow. Meanwhile, they ignore live flesh, and in fact, give it a gentle
growth-stimulating massage simply by crawling over it. When they metamorphose into flies, they leave without a trace –
although in the process, they
might upset the
hospital staff as they squirm around in a live patient. When sulfa drugs, the first
antibiotics, emerged
around the time of World War II, maggot therapy quickly faded into obscurity.
