Disease Warriors Before there was an understanding of infectious disease, few weapons were available to fight it. Disease Warriors chronicles the groundbreaking work of early researchers, such as the famed scientist Louis Pasteur, who unmasked germs as the source of illness. Pasteur went on to develop a rabies vaccine -- a great scientific triumph. Today, vaccines have made huge strides against epidemics, conquering smallpox and bringing the global eradication of polio within reach. But the world still faces major challenges in getting basic vaccines to those who still need them, and in creating new ones to combat modern nemeses, like AIDS. Rise of the Superbugs ItÕs difficult to imagine a world without medicines - and yet, before the twentieth century there werenÕt any. The discovery of the very first antibiotic, penicillin, and the subsequent development of more Òwonder drugsÓ transformed the face of modern medicine. Rise of the Superbugs chronicles these historic successes, as well as the growing threat posed by new strains of germs, such as tuberculosis and staph, that are resistant to our best antibiotics. Are our strongest medicines becoming obsolete, and can we develop new drugs in time to replace them?
