Scientists find new superbug spreading from India

A new superbug from India could spread around the world -- in part because of medical tourism -- and scientists say there are almost no drugs to treat it.

Researchers said on Wednesday they had found a new gene called New Delhi metallo-beta-lactamase, or NDM-1, in patients in South Asia and in Britain.

U.S. health officials said on Wednesday there had been three cases so far in the United States -- all from patients who received recent medical care in India, a country where people often travel in search of affordable healthcare.

NDM-1 makes bacteria highly resistant to almost all antibiotics, including the most powerful class called carbapenems. Experts say there are no new drugs on the horizon to tackle it.

"It's a specific mechanism. A gene that confers a type of resistance (to antibiotics)," Dr. Alexander Kallen of the U.S. Centers for Disease Control and Prevention in Atlanta said in a telephone interview.

With more people traveling to find less costly medical treatments, particularly for procedures such as cosmetic surgery, Timothy Walsh, who led the study, said he feared the new superbug could soon spread across the globe.

"At a global level, this is a real concern," Walsh, from Britain's Cardiff University, said in telephone interview.
