131,300 Pounds of E. Coli

1 Tyson Recalls Ground Beef After Illnesses

Tyson Fresh Meats Inc. recalled around 131,300 pounds of contaminated ground beef, says the U.S. Department of Agriculture. MSNBC reports that Tyson decided to recall the beef because a family in Ohio became ill after eating the meat that contained E. coli. The recall involves ground beef sold as Kroger brand at Kroger and Butcher's Beef at Food Lion, as well as generic beef sold at SAV-A-LOT, Spectrum Foods, Supervalu and Defense Commissary Agency. The affected products were produced by Tyson on August 23. Kroger notes that the products would have been removed from shelves on September 12, but loyalty card customers who bought the meat will be contacted, and in-store signs will be used to notify other consumers. Customers should dispose of any recalled meat that may be in their freezers.

Viral Coat Is Crucial

2 Altered HIV Stimulates Immune System

Scientists at John Hopkins have found that by altering the cholesterol-rich coat that surrounds HIV, the adaptive immune system can be triggered. HIV targets immune cells and when it infects them, such an excess of interferons are released which ultimately inhibits their ability to attack the virus. Researchers chemically removed the cholesterol from the viral coat and incubated human immune cells with both the modified and normal HIV. The modified virus did not elicit the release of interferons from immune system cells, but when it was exposed to 10 samples of HIV-negative blood from different people the adaptive immune response was stimulated. These results provide a framework for developing a vaccine and more effective drugs to fight the virus that causes AIDS.
