>> It is the end of the road.>> Researchers announcing on Thursday for the first time in the US, the discovery of a superbug resistant to all antibiotics in a patient in Pennsylvania. It's an alarming discovery that could mean the end of antibiotics, as we know them. As Reuters correspondent, Ransdell Pierson.
>> This superbug has a gene, which confers resistance to a drug called colistin, which is the drug of last choice. If you fail every other antibiotic, colistin is the one they've held in reserve. This is the first time in US history where this gene, which renders resistance to this drug has been seen.
>> We risk being in a post antibiotic world.>> Tom Frieden who's the head of the Centers for Disease Control of the United States, said that it could herald a no antibiotics world where, potentially nothing would work for people that are infected with this super-bug. It's kind of scary to hear the head of the CDC saying that he's really scared.
>> CDC officials working with Pennsylvania authorities to identify how a 49-year old woman could have contracted the superbug and who she may have come into contact with.>> She hasn't traveled in five months and the implication there is that she got it here in the United States, and didn't bring it back from somewhere else.
We don't really know the epidemiology of how she got it. Microbiologist has I spoke to today said, she's quite concerned it could spread from animals to people. And therefore, food. Another thing, potentially that people could do to protect themselves in the meantime until we get a better handle on things is to wash your hands.
Wash your food very carefully. Make sure the foods are prepared properly and measures like that. Common sense measures in the meantime.>> In November, the deadly strain had been found in people in China, then later in Europe. Scientist express in grave concern that if these antibiotics resist in bug continues to spread, routine infections could pose serious danger.
