US reports first case of bacteria resistant to antibiotic of last resort

'It is the end of the road for antibiotics unless we act urgently,' says Centers for Disease Control and Prevention after superbug infects Pennsylvania woman

For the first time, a US patient has been infected with bacteria resistant to an antibiotic used as a last resort, scientists said Thursday.

The patient, a 49-year-old woman in Pennsylvania, has recovered but health officials fear that if the resistance spreads to other bacteria, the country may soon see supergerms impervious to all known antibiotics.
