Three University scientists have reported the latest results of their study on the chemistry of heredity in bacteria...
...coast. But against his will and judgment, Dr. Ritchie got involved in experiments that ran counter to all accepted theory. In Britain's Lancet, he tentatively reports success in two highly unorthodox attacks on the common cold -with vaccines and antibiotics, working not against viruses but against the bacteria which are always present in the throat and nasal passages...
From employees of Lever Bros, he drew volunteers, some to receive a vaccine, others to get only an inert substance for comparison. Dr. Ritchie wasted no time chasing the will-o'-the-wisp virus (or viruses) that cause the first stages of a cold. He concentrated on the bacteria, believing that they cause the most distressing middle stages. He took throat swabs and saliva from his subjects, threw away those from the 75 controls. From the other 109 he cultured the bacteria to make sure there were no deadly strains among them, then hand-tailored an individual "autogenous vaccine...
Still Scairt. Encouraged by this evidence that most of the trouble in colds is caused by the victims' permanently resident bacteria, which go on a rampage only after the virus has prepared the ground for them, Ritchie decided to try prevention with antibiotics, although their too-free use for colds is frowned upon. To minimize the risks of sensitizing the subjects to the drugs or helping resistant strains of microbes to emerge, he decided to use very small doses, in tablets to be sucked twice a day when the first sniffles appeared. Ritchie used the three closely related antibiotics...
...family cellar, cultivated molds in his mother's fruit jars. In 1929 the famed Pasteur Institute of Paris offered Biologist Bovet a job. By 1932 news reached Paris that Germany's Gerhard Domagk had found that a dye product, prontosil could be used to kill bacteria that cause common infections. Bovet and his colleagues at the Pasteur found that prontosil was "a clumsy, complex chemical," set about breaking it down. After months of night-and-day work they found the essential germ killer in it: sulfanilamide, first of the modern wonder drugs that work directly on the cause...
