  • "In 1884, German scientist Friedrich Loeffler siolated the diphtheria bacillus from throats of patients, grew it on a special medium (laboratories today still use 'Loeffler's serum slope' to grow the bacteria from suspected cases), and began careful experiments in animals that took several years. His work suggested that the bacteria themselves did not kill; the danger came from a toxin, a poison, that the bacteria excreted."
    —John M. Barry, The Great Influenza (NY: Penguin Books, 2004), 69
