...neutralizing toxins, it can stop bacteria from multiplying at the early stages of disease, according to Michèle Mock, team leader on the Institute's anthrax vaccine project. The current anthrax vaccine only neutralizes toxins. The same is true for a vaccine against tularemia, or rabbit fever, a bacterium that can cause fatal illness. With funding from the U.S. government, the University of Ume? in Sweden is trying to identify protective components of the tularemia bacterium and use them to develop a vaccine. And in Germany, scientists are developing a vaccine against botulism toxin. None of them will...
...astonished by the story about the vaccine made from freeze-dried tomato juice that comes from fruit carrying a gene from a strain of the E. coli bacterium. This vaccine can fight off diarrheal diseases. I didn't realize such a thing was possible. I'm glad to know there are scientists trying to find better ways to combat disease in impoverished Third World countries. MARIA MAMAH Union Springs...
...about 100 students and teachers fell ill with various symptoms of vomiting, abdominal cramps and bloody diarrhea; a handful were rushed to the hospital. The culprit? Clostridium perfringens, a bacterium that resides in the intestines of animals but is usually killed when meat is properly prepared. In a report titled "An Uninvited Guest at Turkey Day," state inspectors found that Little Woods' cooks did not monitor the temperature of the turkeys as they cooked. The officials also noted some other uninvited guests: an infestation of cockroaches in the kitchen. "It's bad enough that we have to think about safety...
...safer place. Arntzen, an Arizona State University biologist, has been working for nearly five years to create what is basically freeze-dried tomato juice--but not from any ordinary tomatoes. This fruit (yes, tomatoes are fruits, not vegetables) carries a gene from a strain of the E. coli bacterium. Some strains of E. coli can cause violent diarrhea and death. Swigged down in reconstituted juice, however, a protein made by the E. coli gene should act as a vaccine, priming the immune system to recognize and fight off the real thing...
What's tricky about listeria is that unlike most food-borne pathogens, it can multiply in the refrigerator. Pasteurization and cooking will kill the listeria bacterium, but contamination often occurs later in processing. So you might bring home some ready-to-eat deli meats, hot dogs or soft cheeses that have a trace of listeria contamination on them, put them in the fridge and a week or so later, while they still look fresh, find yourself eating a listeria-packed meal. Not that you would know right away. The symptoms of listeriosis can take anywhere from a few days...
