.....DISCOVERY OF MORE TRUTH
ABOUT HUMAN LIFE-SAVING
ANTIBIOTICS.... |
|
....but first today's life-sciences facts: |
"In all of these newly discovered bacteria,
resistance was found to virtually every antibiotic
that doctors currently use to treat patients"
(according to the study published in the journal PLoS ONE
on April 111, 2011)
|
The study shows that antibiotic resistance
isn’t just man-made.
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,”
|
....But
the good news is that
where there is
resistance among bacteria in the environment, g there must also be natural antibiotics
other micro-organisms
have created...
|
“What all this really means is that
there’s also a broad range of antibiotics we’ve yet to discover,”
said Dr. Barton,
noting that the researchers have already isolated one
and are working with a pharmaceutical company to develop it into a drug.

BEFORE YOU SCROLL
TO TODAY'S DISCOVERY NEWS....
here is a little primer about the superbug named as MRSA.... |
A study conducted at Pennsylvania State University has discovered
one of the mechanisms that enables hospital superbug MRSA to develop a
resistance against antibiotics. Scientists are now set on using the new
findings to develop a drug that can stop the infection.
The researchers found out that MRSA bacteria contain a special CFR
protein that hinders antibiotics to attach themselves to the ribosome of
the bug. Unless they are able to dock on to this protein-producing part
of the bacteria and cut the bug's vital protein supply, antibiotics will
not be effective....(you can read the full report by clicking

Ancient cave discovery unlocks
secrets of
superbugs |

knowledge words provided by PVAF volunteers....) |
Deep inside a cave in New Mexico, researchers have made a startling
discovery – bacteria that are resistant to
antibiotics, yet have been
pristinely isolated from human contact for more than four million years.
(see Note 1)
Bacterial resistance
to antibiotics – the
infection-killing wonder drugs
that began with mass-produced
penicillin in the early 1940s – was long
thought to have arisen because of wholesale and indiscriminate use of
the medications to treat disease in both people and animals.
Over time, more and more disease-causing bacteria, including the
superbug MRSA, are becoming immune to most antibiotics now in use. And
the growing number of bugs mutating to dodge the killing effects of the
drugs has researchers and pharmaceutical companies scrambling to find
new agents.
But the discovery of species of naturally resistant bacteria in the
Lechuguilla Cave, in
Carlsbad Caverns National Park, represents a major
leap in the understanding of resistance threatening the treatment of
infectious diseases around the world.
The conclusion: it isn’t just man-made.
“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 co-principal investigator
Gerry Wright, scientific director of the
Institute for Infectious
Disease Research at McMaster University in Hamilton.
“This has important clinical implications,” Dr. Wright said. “It
suggests
that there are far more antibiotics in the environment that
could be found and used to treat currently untreatable infections.”
That’s because a particular bacterium creates its own antibiotic as a
means of fighting off other bacteria, said co-author Hazel Barton, a
cave microbiologist at the University of Akron who helped recover the
micro-organisms within the New Mexico cave.
One way to think of it is the bacterial version of
The Hunger Games –
kill or be killed.

“They’re carrying out
germ warfare, so it’s like an
arms race,” said
Dr. Barton, explaining that the bacteria are competing for scarce food
resources in their environment, whether in backyard soil or deep within
a cavern.
“These chemical weapons that they make are antibiotics,” she said.
“So these organisms have adapted by developing resistance to those
chemical weapons. So even though somebody comes along and spits this
weapon at them, they can defend themselves and that’s where resistance
comes from.”
While most of us think of antibiotics as pills from a bottle, most in
fact originated in nature, like the mould identified by Scottish
biologist Alexander Fleming in 1928 that gave rise to
penicillin.
“If you look at it in the soil, you’ve got one bacterium next to another
bacterium,” she said. “That bacterium is squirting out the same drug
that you have in that pill.”
In never-before-visited recesses far inside the Lechuguilla Cave,
researchers collected strains of bacteria, scraping them off the
surfaces of rock. An analysis showed none are capable of causing human
disease and almost all were resistant to at least one antibiotic, with
some able to fend off up to 14 of the drugs.
In all, resistance was found to virtually every antibiotic that doctors
currently use to treat patients, according to the study published in the
journal PLoS ONE. (See Note 1)
The good news is that where there is resistance among bacteria in the
environment, there must also be natural antibiotics other
micro-organisms have created.
“What it means is that there’s also a broad range of antibiotics we’ve
yet to discover,” said Dr. Barton, noting that the researchers have
already isolated one and are working with a pharmaceutical company to
develop it into a drug.
“So we’re just hunting them down now.” |
