...Centers for Disease Control warned last September that the risk of toxic shock syndrome (TSS), a rare but sometimes fatal bacteria-related disorder that usually strikes menstruating women, might be heightened by the use of tampons, particularly the Rely brand from Procter & Gamble. Since that alert and the prompt removal of Rely from the market, the incidence of TSS has dropped dramatically. The CDC announced last week that the number of new cases in the U.S. reported each month had declined from 106 in September to 39 in December...
Infant Botulism. Botulism usually comes from eating improperly canned food contaminated by toxin produced by the bacterium Clostridium botulinum. Four years ago, researchers at the California health department found that babies with no obvious exposure to such canned foods were coming down with the disease. C. botulinum bacteria are ubiquitous. They thrive in the earth and are spread as spores through dust in the air as well as on vegetables, fruits or in honey. Adults regularly ingest the microbes but customarily suffer no harm. The spores remain dormant in the adult intestine. For as yet unknown reasons, the intestines...
...itself, tetracycline will not prove useful because the layers of bacteria in periodontal disease are to great for the drug to penetrate and inhibit," Gordon said, but he added that the drug will probably be effective in conjunction with other therapy...
Jeffcoat said there are still unanswered questions about the effectiveness of tetracycline because some beagles are resistant to the drug. Some humans might be resistant or develop a resistance to the drug, she said, adding, "We don't know if the same bacteria is involved in humans...
...university laboratories across the U.S., scientists are manipulating genes to create new forms of life: tiny bacteria that might be able to clean up toxic chemical wastes or produce anticancer agents on a grand scale. The potential profits from this work are so enormous that many researchers have set up companies like the highly touted Genentech. Now the schools themselves are looking for test-tube gold. In what would be an unprecedented step, Harvard University is considering starting a genetic-engineering firm to cash in on its scientists' breakthroughs. President Derek Bok has called for faculty comment...
