The number of cases began increasing in February and then, more dramatically, in March. On 21 March, Marburg virus wa...

Promising new West Nile therapy cures disease in mice

...the blood might harbor other potentially dangerous infectious agents. The Washington University scientists made 46 monoclonal antibodies against West Nile virus and then eliminated the less effective ones through a tedious molecular-level screening process. They then turned to Rockville, MD-based MacroGenics I...

Microbial forensics: The next great forensic challenge

... ever because of rapidly expanding knowledge about infectious diseases and biotoxins and their potential to wreak havoc in complex, interdependent societies. The nation is in the process of developing a strong microbial forensic program to attribute and prosecute such attacks, and perhaps deter them. The oppor...

Biologists discover why 10% of Europeans are safe from HIV

...dea that the plagues of Europe were not a directly infectious disease but were outbreaks of bubonic plague, overturning an accepted belief that had stood for 550 years. Professor Duncan and Dr Scott illustrated in their book, Return of the Black Death (2004, Wiley), that this idea was incorrect and the plagues ...

Leprosy microbes lead scientists to immune discovery

...ensive cells, macrophages, seek out and engulf the infectious bugs. The other group consists of dendritic, or "antigen-presenting" cells, which seize distinctive pieces of the enemy and use them to "educate" and stir up a second immune response, known as "adaptive" immunity. Until now, laboratory dish experime...
