...Topical creams or burn dressings containing silver sulfadiazine and sulfa derivatives are being used in addition to the traditional method of sterilization-bathing burns with 0.5% silver nitrate solution. The new dressings cut the rate of infection by pseudomonas bacteria-once the primary cause of burn deaths-in half. In addition, Dr. Irving Feller of the University of Michigan burn center in Ann Arbor has developed a treatment that combines infusions of blood plasma from immunized donors with shots of anti-pseudomonas vaccine. The treatment, which has been in use since 1965, has cut the infection death rate from...
...Eaters. Other scientists are trying to make use of the long-known fact that some bacteria "eat" oil. Can this be applied to oil spills at sea? Though well-funded research projects are under way at such famous oceanographic centers as Rutgers University and Florida State University, the most promising results have come from a small, modestly financed firm in Springfield, Va. Going beyond most other researchers, Bioteknika International Inc. has produced a special microbe "cocktail" that seems to break oil down into carbon dioxide, water, sugars and proteins−all of which enhance marine life...
...produced in active, living cells. If spores and other dormant forms of life were the only inhabitants of clouds, as most scientists have assumed, they would not become active and respond to the test for at least an hour. But when Parker collected airborne and presumably dormant samples of bacteria, algae and fungi and doused them with TTC, the chemical began turning pink in only 15 to 20 minutes the time it usually takes active cells to react. As a double check, he placed some of the samples in containers of radioactively labeled carbon dioxide. When exposed to light...
...life in the clouds is as widespread as Parker suspects, biologists will have whole new ecological possibilities to explore. Clouds may well spread disease, for example, by harboring harmful viruses or bacteria. On the other hand, organisms that thrive on the ingredients of smog and smoke could help in the fight against air pollution. Introduced into clouds, they would feed on the undesirable gases and particles, thus converting pollution into harmless cloud creatures...
...American Public Health Association, many hospital staffers believe that antibiotics have made frequent hand washing unnecessary. But the A.P.H.A. reports that about 5% of all patients now incur infections during their hospital stays. Almost 40% of nurses, for example, were found to carry resistant strains of infection-producing bacteria. An unpublished study by the faculty of the Columbia University College of Physicians and Surgeons identified even worse offenders: "One of the most persistent purveyors of germs in a given hospital department is the chief of that unit. Because he is at the top of the pecking order...
