Consumers will soon have more safe handling information and new refrigeration requirements to help prevent foodborne illness from eggs contaminated with Salmonella Enteritidis.
Egg-associated salmonellosis is an important public health problem in the United States and several European countries. A bacterium, Salmonella enter-itidis, can be inside perfectly normal-appearing eggs, and if the eggs are eaten raw or undercooked, the bacterium can cause illness. During the 1980s, illness related to contaminated eggs occurred most frequently in the northeastern United States, but now illness caused by S.enteritidis is increasing in other parts of the country as well. Consumers should be aware of the disease and learn how to minimize the chances of becoming ill.
For years, researchers studying stem cells have been intrigued by the possibility that these cells might be used to treat brain diseases. Recent studies have suggested that neural stem cells transplanted into the brain can migrate throughout the brain and develop into other types of cells. Now, two new studies show that bone marrow cells transplanted into mice can migrate into the brain and develop into cells that appear to be neurons. The studies suggest that bone marrow may be a readily available source of neural cells with potential for treating such neurological disorders as Parkinson's disease and traumatic brain injury.
An essential component of efforts to prevent new human immunodeficiency virus (HIV) infections in the United States is the use of voluntary HIV counseling and testing by persons at risk for HIV, especially members of underserved populations. To increase the number of persons at risk for HIV who receive voluntary HIV counseling and testing services, barriers to these services must be identified and removed. The stigmatization of persons infected with HIV and the groups most affected by HIV, including men who have sex with men and illicit drug users, is a barrier to testing.
