New antibiotic beats superbugs at their own game |
|
Thursday, 03 July 2008 |
|
The problem with antibiotics is that, eventually, bacteria outsmart
them and become resistant. But by targeting the gene that confers such
resistance, a new drug may be able to finally outwit them. Rockefeller
University scientists tested the new drug, called Ceftobiprole, against
some of the deadliest strains of multidrug-resistant Staphylococcus
aureus (MRSA) bacteria, which are responsible for the great majority of
staphylococcal infections worldwide, both in hospitals and in the
community.

Breast-Feeding, Antiretroviral Prophylaxis, and HIV |
|
Thursday, 03 July 2008 |
|
More than 200,000 of the 500,000 new human immunodeficiency virus (HIV) infections that occur each year in children are the result of transmission of the virus through the mother's breast milk.1 In resource-constrained environments, how do we continue to promote breast-feeding, an important intervention for child survival,2 without exposing more infants to this risk? This fundamental question plagues mothers and caregivers, especially in sub-Saharan Africa, where such choices are made every day.

Penn Animal Study Identifies New DNA Weapon Against Avian Flu |
|
Thursday, 03 July 2008 |
Researchers at the University of Pennsylvania School of Medicine have identified a potential new way to vaccinate against avian flu. By delivering vaccine via DNA constructed to build antigens against flu, along with a minute electric pulse, researchers have immunized experimental animals against various strains of the virus. This approach could allow for the build up of vaccine reserves that could be easily and effectively dispensed in case of an epidemic. This study was published last week in PLoS ONE.
