Silent Killers:
Fantastic Phages?
(CBS) After breaking his
foot five years ago, Toronto bass player Alfred Gertler got an infection
that antibiotics couldn’t cure. Doctors told him he might have to have his
foot amputated.
But then he read about a radically different way to treat
infections. The treatment was in the former Soviet Republic of Georgia, at
the Eliava Institute in Tbilisi.
“It was very strange. But it seemed like a lifeline,” he
says. So he went. “They had no heat, no electrical power, no water for
much of the day,” says Gertler.
What Eliava did have was treatment that worked. They
poured an ointment in the wound and within three days, the infection was
gone. Susan Spencer reports.
The treatment used something called bacteriophage – or
“phage” as some call it. Researchers at Eliava are convinced that phages
are a fine, natural alternative to antibiotics. Phages are harmless
viruses that have only one purpose in life: to eat bacteria that cause
infection. Susan Spencer reports that they could help overcome our
dangerous dependence on antibiotics.
“A miracle of nature is that there seems to be a
bacteriophage for every kind of bacteria,” says Michael Shnayerson,
co-author of “The Killers Within.” He says these viruses may work when
antibiotics fail. “Given the fix that we're in with the rise of
resistance, we need to look at other approaches. And phage is just one of
several,” says Mark Plotkin, the other co-author.
This approach is nothing new at Eliava, where they have
been making phage medication for more than 60 years. They use techniques
that are not cutting-edge: They isolate bacteria and then search for the
specific phages that kill them.
In local hospitals, doctors use phages to treat wounds. In
clinics, phages are used to treat throat infections. For burns, there is
phage bio-derm, artificial skin with time-release medication.
“Everybody knows what this is, and it’s just a standard
part of health care,” says Mzia Kutateladze, a senior scientist at Eliava.
The price is right too: $2.50 for ten ampules.
But if phages are so great why aren’t doctors in the U.S.
using them, just as the doctors in Georgia do? The answer: penicillin.
“Nobody cared very much once penicillin came along in the western world.
They thought they had the problem licked for all time. We have a lot of
hubris a lot of time,” says Betty Kutter, a microbiology professor from
Evergreen University, who believes passionately that phage therapy works.
With Eliava, she hopes to convince others that using a
naturally-occurring virus to fight an infection is a fine idea. “These are
viruses that can absolutely not infect human cells, or animal cells, or
plant cells,” she says. “No chance of getting sick from the treatment. The
only kind of cells they infect is bacteria.”
Kutter brought Gertler to Eliava. She says his foot would
have been amputated without phage treatment. Gertler’s treatment would be
off-limits in the U.S. because phage therapy has never gone through the
rigorous testing the U.S. demands.
And consider where phages are found: “We isolate the new
phage clones from sewage,” says Mzia with a laugh. “Not a very clean
place. But it has a lot of phages.”
Will Americans be willing to try a medicine that is made
from sewage, has viruses in it, and is used in the former Soviet Union?
“You can trust it because it works and it has been working during so much
time for so long,” says Mzia.
Now, some American entrepreneurs want to give this old
technology new consideration.
Intralytix in
Baltimore is one of a few small companies starting carefully controlled
studies.
“There’s no question that on the test tube and on the
culture plate, these things look like gang busters,” says infectious
disease specialist Glenn Morris,
co-founder of the company. “Translating that into something that’s
effective in terms of human therapy; there’s a lot to suggest that they do
work. But at least in this country, we still have to prove it.”
That will take at least 3 to 5 years, he says, even using
Eliava's experience. And who knows where Eliava will be then. The collapse
of the Soviet Union cut off funding for research, equipment, and workers.
Today, Eliava struggles just to hang on to its unique phage inventory.
There has been recent outside help, including new
equipment and a grant from the U.S. State Department. “It’s very hopeful.
And this is the only way to save our science and just keep going,” says
Mzia.
No one thinks phages will replace antibiotics completely,
but they may be part of the answer when antibiotics don’t work. “I think
we’re absolutely crazy if we don’t learn to use them and to use them well
and efficiently and effectively,” says Kutter.
