E. coli bacteria are found in healthy bodies, but some forms can cause illness, paralysis, and even death. This book traces the history of this mutating menace, reviews efforts to contain outbreaks when they occur, and where medical science is in efforts to find treatments. There is a timeline on the discovery, treatment, and outbreaks of E. coli, and sidebars on a young dancer who was paralyzed by bacteria in her burger, and the dangers of kiddie pools.
