...style protesters was a quintessentially '90s issue: whether a genetically engineered hormone that went on sale last week after nearly 10 years of legal wrangling threatens the safety of American milk. The hormone, a natural protein found in cows, is being artificially manufactured in vats of genetically altered bacteria. When cows are regularly given extra doses of the hormone, their milk production can rise as much as 15%. Scientists call the chemical bovine somatotropin (BST) or, more simply, bovine growth hormone (BGH), and it is marketed under the trade name Posilac...
...Outbreaks of Mycoplasma pneumoniae, a bacteria that causes a particularly virulent respiratory illness, have struck New York, Ohio and Texas. The cold- like bug could spread rapidly as winter approaches...
...another first for biotechnology, scientists have isolated a disease- resistant gene in one type of tomato, cloned it and inserted it into a variety of tomato that lacks that gene. The cloned gene signals the plant's defense system to ward off an invasion by bacteria that cause a leaf- destroying disease known as speck. Researchers predict that similar advances with other crops will significantly reduce the need for pesticides by the end of the century...
...just the environmentalists who see a problem. A survey by the federal Centers for Disease Control shows that in 1989 and 1990, 4,288 people in 16 states got sick, and four died, from bacteria and viruses in their water. And last spring the nonpartisan General Accounting Office found, among other things, that many water systems do not test for all the pollutants the EPA considers dangerous, and don't evaluate distribution systems, operators or inspectors. Based on these and other studies, the N.R.D.C. has identified several especially worrisome hazards...
PATHOGENS: These include bacteria, viruses and protozoa such as the cryptosporidium that struck Milwaukee. These sicken 900,000 people a year, says the N.R.D.C. report, and kill perhaps 900, usually those with weak immune systems (the very young and very old, AIDS sufferers and organ-transplant patients...
