Discovery of antibiotic-resistant bacteria in ancient cave could lead to
cure for superbugs

Bugs hidden from outside world for four million years
Resistance believed to be result of over use of drugs
But this discovery shows it is 'hard-wired' in nature

Antibiotic-resistant bacteria cut off from the outside world for more than
four million years have been found in a deep cave.

The discovery is surprising because scientists had thought bacteria built up
resistance to antibiotics after being repeatedly exposed to the treatment.

However, the resistant bugs from Lechuguilla Cave in New Mexico, U.S., have
had no contact with humans, suggesting the environment may be to blame.

They are thought to have picked up their resistance from natural
anti-bacterial chemicals in the environment.

'Our study shows that antibiotic resistance is hard-wired into bacteria. It
could be billions of years old, but we have only been trying to understand
it for the last 70 years,' said Dr Gerry Wright, from McMaster University in
Canada, who has analysed the microbes.

'This has important clinical implications. It suggests that there are far
more antibiotics in the environment that could be found and used to treat
currently untreatable infections.'

The research is published in the online journal Public Library of Science
ONE.

Lechuguilla Cave, which reaches to a depth of 1,604 feet, is one of the
largest and deepest unspoiled cave systems in the world.
'Hard-wired': It is widely thought that antibiotic-resilient bacteria like
MRSA (above) are caused by over-use of medication, but this find suggests
otherwise

It is surrounded by an impermeable layer of rock discovered in 1986, and
access to the cave is limited to a handful of expert cavers and researchers
each year.

The bacteria were collected from some of the deepest and most isolated
recesses of the cave and tested for antibiotic resistance.

Researchers found that while none of the bacteria are harmful to humans,
almost all were resistant to at least one antibiotic and some to as many as
14 different drugs.

Overall, resistance was seen to virtually every antibiotic in current use by
doctors.

'Most practitioners believe that bacteria acquire antibiotic resistance in
the clinic,' said Dr Wright.

'As doctors prescribe antibiotics, they select for members of the community
that are resistant to these drugs.

Over time, these organisms spread and eventually the bacteria that commonly
cause these infections are all resistant.

'In extreme cases these organisms are resistant to seven or more drugs and
are untreatable using traditional treatment, and doctors must resort to
surgery to remove infected tissue.

'The actual source of much of this resistance is harmless bacteria that live
in the environment.'

WARNING FROM RAEL: For those who don't use their intelligence at its
full capacity, the label "selected by RAEL" on some articles does not
mean that I agree with their content or support it. "Selected by RAEL"
means that I believe it is important for the people of this planet to
know about what people think or do, even when what they think or do is
completely stupid and against our philosophy. When I selected articles
in the past about stupid Christian fundamentalists in America praying
for rain, I am sure no Rael-Science reader was stupid enough to
believe that I was supporting praying to change the weather. So, when
I select articles which are in favor of drugs, anti-semitic,
anti-Jewish, racist, revisionist, or inciting hatred against any group
or religion, or any other stupid article, it does not mean that I
support them. It just means that it is important for all human beings
to know about them. Common sense, which is usually very good among our
readers, is good enough to understand that. When, like in the recent
articles on drug decriminalization, it is necessary to make it
clearer, I add a comment, which in this case was very clear: I support
decriminalizing all drugs, as it is stupid to throw depressed and sad
people (as only depressed and sad people use drugs) in prison and ruin
their life with a criminal record. That does not mean that there is
any change to the Message which says clearly that we must not use any
drug except for medical purposes. The same applies to the freedom of
expression which must be absolute. That does not mean again of course
that I agree with anti-Jews, antisemites, racists of any kind or
anti-Raelians. But by knowing your enemies or the enemies of your
values, you are better equipped to fight them. With love and respect
of course, and with the wonderful sentence of the French philosopher
Voltaire in mind: "I disapprove of what you say, but I will defend to
the death your right to say it".

"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.

There is nothing glorious about what our ancestors call history, 
it is simply a succession of mistakes, intolerances and violations.

On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.
