There is no evidence that a new superbug resistant to most antibiotics will be any more dangerous than other known superbugs, according to new reports.

A newly discovered gene variant, called NDM-1, has been found to cause extreme resistance to antibiotics in some bacterium. The superbugs have been transferred form India and Pakistan to such countries as Australia, Canada, Sweden, the United States and the United Kingdom. They accompany medical tourists who travel to Asian countries for less expensive treatments. But new research indicates that the new superbugs would not be more dangerous than methicillin-resistant Staphylococcus aureus (MRSA) or other anti-biotic-resistant bugs, the LA Times reported.

Experts at the Centers for Disease Control and Prevention have said that there have not been new cases involving the NDM-1 superbugs in the U.S. since an initial health warning in June of this year. They also note that the bugs are susceptible to some older antibiotics. Overuse of antibiotics among the large populations in India and Pakistan could have contributed to the increased resistance among the new bugs, despite the high quality of many of those countries’ hospitals, according to the Times.
