British scientists have identified NDM-1, an enzyme that turns bacteria into superbugs resistant to antibiotics, in 180 patients in the U.K., India and Pakistan. (CBC)New strains of bacteria with the ability to resist even the strongest antibiotics have emerged in India and spread worldwide, including to Canada, researchers warn.
British scientists have discovered bacteria that are able to make an enzyme called NDM-1, or New Delhi metallo-beta-lactamase 1.
Genes enable the bacteria to make the enzyme so they can flourish even in the presence of nearly all known antibiotics.
"I think we should be very worried that the value of antibiotics is being eroded," said study author Dr. David Livermore.
The strains have been found in 180 people in India, Pakistan and the U.K. At least 17 of these had a history of travelling to India or Pakistan, Livermore and his co-authors said in Wednesday's issue of the journal Lancet Infectious Diseases.

Antibiotic resistance
From Wikipedia, the free encyclopedia
(Redirected from Super bug (bacteria))
Antibiotic resistance is a type of drug resistance where a microorganism is able to survive
exposure to an antibiotic. Genes can be transferred between bacteria in a horizontal fashion
had evolved via natural selection may be shared. Evolutionary stress such as exposure to
antibiotics then selects for the antibiotic resistant trait. Many antibiotic resistance genes
reside on plasmids, facilitating their transfer. If a bacterium carries several resistance genes,
it is called multiresistant or, informally, a superbug.
The primary cause of antibiotic resistance is antibiotic use both within medicine and veterinary
medicine.The greater the duration of exposure the greater the risk of the development of resistance
New Delhi: Just days after the Indian government rubbished a report in
The Lancet Infectious Diseases study, that suggested that a superbug had
evolved in India, the World Health Organisation (WHO) has endorsed the
report.

"An article published in The Lancet on 11 August 2010 identified a new gene
that enables some types of bacteria to be highly resistant to almost all antibiotics.
The article has drawn attention to the issue of AMR, and, in particular, has raised
awareness of infections caused by multi-drug resistant bacteria," the statement says.
In hope to make a difference !!!!!!
