The World Health Organization announced its first list of antibiotic-resistant “priority pathogens” on Monday, detailing 12 families of bacteria that agency experts say pose the greatest threat to human health and kill millions of people every year.
The list is divided into three categories, prioritized by the urgency of the need for new antibiotics. The purpose is to guide and promote research and development of new drugs, officials said. Most of the pathogens are among the nearly two dozen antibiotic-resistant microbes that the U.S. Centers for Disease Control and Prevention warned in a 2013 report could cause potentially catastrophic consequences if the United States didn't act quickly to combat the growing threat of antibiotic-resistant infections.
“This list is not meant to scare people about new superbugs,” said Marie-Paule Kieny, an assistant director-general at WHO. “It's intended to signal research and development priorities to address urgent public health threats.”
