Susan M. Hanley, 29, of Cambridge, is a research associate in a genetics research company, BioTechnica International, working in yeast mold biology. While she was an undergraduate, Hanley majored in chemistry, but has spent the last seven years researching E. coli, a common bacterium...
...made by the Jalisco Mexican Products Inc. plant in Artesia, Calif., whose major markets are in nine Western states. But 22 deaths or stillbirths in Los Angeles County have been linked to the soft white cheeses, which federal health officials say were contaminated with the deadly and fast-acting bacterium Listeria monocytogenes. In virtually all of the 94 confirmed cases, Hispanics have been the victims...
...bacterium causes a flulike disease that is most dangerous for people with low immunity, such as the elderly, pregnant women and infants. After the Centers for Disease Control in Atlanta last week established the link between the outbreak and the cheese, the cheese products made by the 17-year-old Jalisco firm were removed from store shelves throughout the U.S. So far, no source has been found for the contamination, and county health officials are at a loss to explain how the deadly organisms could have survived the heat of pasteurization...
Researchers have known for several years that TSS is caused by a toxin produced by a common and usually harmless bacterium called Staphylococcus aureus. In laboratory studies, the Harvard team, led by Infectious Disease Specialist Edward Kass, found that the bacterium produces up to 20 times as much toxin as usual in the presence of certain tampon fibers. Kass's group discovered that the fibers -- polyester foam and polyacrylate rayon -- soak up large amounts of magnesium, which is normally present in vaginal tissue and fluid. When the magnesium is removed from the bacterium's environment, the bug responds by churning...
...bacterium involved in the current outbreak appears to be resistant to antibiotics. Because it can remain dormant and is also contagious, health experts fear that as many as 10,000 people could eventually contract the infection, which causes vomiting, diarrhea and fever. While the search goes on for the exact source of the bug, Jewel has shut its suspect dairy and removed all its dairy products from its 217 outlets. Workers at several Chicago-area stores poured thousands of gallons of milk down storm sewers, creating concern that this might allow the bacteria to spread. Jewel cleaned up the potential...
