Beware: New Superbug Widespread in India

UK doctors: New superbug gene could spread widely

Though already widespread in India, the new superbug gene is being increasingly spotted in Britain and elsewhere. Experts warn a surge in antibiotic resistance due to the booming medical tourism industries in India and Pakistan, as patients import dangerous bugs to their home countries.
So far 37 people had been identified with the superbug who returned to the U.K. after undergoing surgery in India or Pakistan. The superbug gene can be swapped between different bacteria to make them resistant to most drugs.
The resistant gene has also been detected in Canada, Australia, the U.S., the Netherlands and Sweden. Since many Americans and Europeans travel to India and Pakistan for elective procedures like cosmetic surgery, it was likely the superbug gene would spread worldwide, the researchers say .
In an article published online Wednesday in the journal Lancet Infectious Diseases, doctors reported finding a new gene, called NDM-1. The gene alters bacteria, making them resistant to nearly all known antibiotics. It has been seen largely in E. coli bacteria, the most common cause of UTI , and on DNA structures that can be easily copied and passed onto other types of bacteria.
The researchers said the superbug gene appeared to be already circulating widely in India, where the health system is much less likely to identify its presence or have adequate antibiotics to treat patients.

"The potential of NDM-1 to be a worldwide public health problem is great, and coordinated international surveillance is needed," the authors wrote.
The numbers of people who have been identified with the superbug gene remains very small, though.
"We are potentially at the beginning of another wave of antibiotic resistance, though we still have the power to stop it," said Christopher Thomas, a professor of molecular genetics at the University of Birmingham who was not linked to the study. Thomas said better surveillance and infection control procedures might halt the gene's spread.
Thomas said while people checking into British hospitals were unlikely to encounter the superbug gene, they should remain vigilant about standard hygiene measures like properly washing their hands.
"The spread of these multi-resistant bacteria merits very close monitoring," wrote Johann Pitout of the University of Calgary, Canada, division of microbiology, in an accompanying Lancet commentary.
International surveillance of the bacteria, particularly in countries that actively promote medical tourism, Pitout emphasized.
" If family doctors have to treat infections caused by these multi-resistant bacteria on a daily basis, the consequences will be serious" he wrote.
