...coats of cows, sheep and dogs for hair, ticks, fleas and fecal matter. "We've excluded the usual bacterial, fungal and parasitic infections," says Dr. Ron Voorhees, a New Mexico state epidemiologist. Ruled out are anthrax, plague and Legionnaires' disease, as well as insecticides and other toxins. Two bacteria are among the suspects: Mycoplasma fermentans and Chlamydia pneumoniae, both of which can cause fatal lung inflammations. But topping the list of possible culprits is a virus...
...disease, toxic-shock syndrome and AIDS over the past two decades. Modern life is constantly creating new opportunities for microbes, warns author and infectious-disease specialist Dr. Richard Krause of the National Institutes of Health. Legionnaires', he notes, developed because air-conditioning ducts created a new breeding ground for bacteria; toxic shock was linked with the introduction of highly absorbent tampons and AIDS with population shifts and changing sexual mores. At week's end investigators were focusing on the possibility that the illness might somehow be linked to inhaling a virus present in rodent droppings, though whether...
MOST OUTBREAKS OF FOOD POISONING ARE TRACED to contaminated meat. Federal investigators have now identified another potential culprit: fresh apple cider, the kind sold at roadside stands or refrigerated in plastic jugs. Tracking a 1991 Massachusetts outbreak of infection with dangerous E. coli bacteria, researchers discovered that most of the 23 victims drank unpasteurized, unpreserved cider purchased at a local farm stand. Scientists warn that some small cider mills do not carefully wash and scrub their apples, which may have dropped to the ground and been tainted with animal droppings. The drink had been thought safe because of its acidity...
...scientists say, is that the hormone can lead to udder infections that not only are painful to cows but also could have consequences for those who drink the milk. Farmers treat the animals with powerful antibiotics that find their way into milk. Humans who drink the stuff can harbor bacteria that develop resistance to those antibiotics, and thus run the risk of developing infections that are hard to treat...
...known for decades that cows given booster shots of BGH would produce more milk -- up to 15% more. But the only available source of the hormone was the pituitary glands of butchered cows, which yield only minute quantities. Then, in 1982, scientists used new gene-splicing techniques to manipulate bacteria into mass-producing BGH. By the mid-1980s, four drug companies -- including Monsanto and Eli Lilly -- had applied to the FDA for permission to market the product...
