...full force, researchers have announced a new blood test that can detect Lyme disease as early as one week after a tick bite. That's a lot better than the current four to six weeks. The new test (not yet widely available, alas) detects antibodies to Lyme bacteria before they build up in the blood. That means patients can get on antibiotics sooner. Another benefit: the test can distinguish between past infections, which may not require medication, and new ones, which...
MEAT ZAPPER Dangerous bacteria like E. coli and Salmonella could be zapped in meat and poultry, but the public has balked at irradiation in foods--even though it's government approved--because it involves powerful gamma rays emitted by radioactive isotopes. Now Titan Corp. in San Diego, Calif., has invented a meat pasteurization system that uses electron beams instead. Approved by the FDA and awaiting final regulations from the USDA, electronically pasteurized meat should be in selected test markets by year...
Today new viruses are coming out of nature and "discovering" the human species, while in hospitals and in jungle clinics exceedingly powerful mutant bacteria are emerging that can't be treated with antibiotics. In the past decade, at least 50 new viruses have appeared, including Ebola Ivory Coast, Andes virus, hepatitis G, Fakeeh, Pirital, Whitewater Arroyo, Hendra virus, Black Lagoon virus, Nipah and Oscar virus. This summer West Nile virus showed up for the first time in the western hemisphere, when it was discovered in New York City...
...breath, though, is, to put it delicately, food molecules rotting in the mouth. Mouthwash masks the smell, but ultimately you have to get rid of the stuff. Brushing and flossing remove larger particles, but dentists suggest brushing the back of the tongue as well, where food residues and bacteria congregate. The microscopic bits that remain must be flushed down by drink or saliva (morning breath occurs because salivation shuts down at night). But if you're waiting for a true cure, it won't happen until we eat all our food in pill form. In other words, don't hold...
Students should also be aware of the vaccine's limitations. The vaccine only offers immunity against four of the nine serogroups of the bacteria that causes meningitis and the vaccine is only effective for one to four years. Additionally, while the vaccine prevents one from contracting meningitis, it does not prevent one from carrying and spreading the disease...
