...blood poisoning, gonorrhea, childbed fever, erysipelas, cerebrospinal meningitis and other bacterial diseases (TIME, Dec. 28, et seq.). Last week conservative bacteriologists of the National Institute of Health announced that this astounding new drug seemed to be a cure for an entirely separate class of diseases, namely, those caused by viruses. Among virus diseases are the common cold, influenza, infantile paralysis, parrot fever. Another disease due to a virus is "benign lymphocytic choriomeningitis," which was recognized as a distinct ailment only a few years ago because almost anything may cause its chief symptoms (headache, vomiting, slight fever). From a case...
Presuming that the virus entered the body only through the nerves of smell, Epidemiologist Charles Armstrong of the U. S. Public Health Service, tried coating the tips of those nerves with spray containing alum. This procedure protected some children exposed to the disease...
Last winter Chemist Wendell Meredith Stanley of the Rockefeller Institute appeared at Atlantic City where the Association for the Advancement of Science was holding its annual meeting, and informed the whole scientific world 1) that a virus was a huge molecule composed basically of nitrogen, carbon, hydrogen and oxygen, weighing 17,000,000 times as-much as a hydrogen molecule, and measuring one seven-hundred-thousandth of an inch in diameter; 2) that he had crystallized a typical virus (which causes mosaic diseases in tobacco plants) by chemical treatment; 3) that he had modified the virus molecule chemically and produced...
...ultracentrifuge (TIME, Feb. 6, 1933), and an X-ray analyzer of crystalline substances. The press enables him to get juices from infected tissue without modifying ingredients in the slightest. The ultracentrifuge, whirling at 50,000 revolutions per minute, separates the ingredients into layers, including one of pure crystalline virus. X-rays prove that this virus, obtained by physical means, is exactly the same as the virus which Dr. Stanley obtained by chemical means...
Rocky Mountain Spotted Fever is caused by a microscopic speck which may be an especially tiny bacterium or an especially big virus. Bacteriologists cannot decide which. It is transmitted to man by a tick called Dermacentor andersoni, which in an unknown manner migrated and adapted itself to the greenery of the Appalachian foothills...
