The World Health Organization has issued a list of the top dozen bacteria most dangerous to humans, warning that doctors are fast running out of treatment options.
WHO's Marie-Paule Kieny said that if such priorities were left to market forces alone, "the new antibiotics we most urgently need are not going to be developed in time." She estimated that it would take up to a decade for new medications.
WHO said the most-needed drugs are for germs that threaten hospitals, nursing homes and among patients who need ventilators or catheters. The agency said the dozen listed resistant bacteria are increasingly untreatable and can cause fatal infections; most typically strike people with weakened immune systems.
