Following the death of three newborns at Chambéry hospital (France) in December 2013, scientists at the Institut Pasteur quickly drew connections to a previously unknown bacterium responsible for the contamination of parenteral nutrition bags. Today, these scientists are publishing an article to announce the official recognition and complete characterization of this bacterium, which belongs to an entirely new genus. In homage to Emile Roux, a close collaborator of Louis Pasteur and head of the Institut Pasteur from 1904 to 1933, the bacterium was named Rouxiella chamberiensis.
