Fine Reading. Proximate and ultimate causes of the bactericidal action of antibiotics
by Elio
In a Perspective piece in Nature Reviews Microbiology, Fernando Baquero of the Ramon y Cajal University Hospital in Madrid and Bruce R. Levin of the Antibiotic Resistance Canter at Emory University present a most thoughtful essay on the ways antibiotics kill bacteria (or don't). To explain the curious title and what's behind it, let me quote their introductory paragraph:
