Nanoparticles containing bee venom toxin melittin can destroy human immunodeficiency virus (HIV) while at the same time leaving surrounding cells unharmed, scientists from Washington University School of Medicine reported in the March 2013 issue of Antiviral Therapy.
The researchers said that their finding is a major step toward creating a vaginal gel that can prevent HIV spread. HIV is the virus that causes AIDS.
Joshua L. Hood, MD, PhD, a research instructor in medicine, said: "Our hope is that in places where HIV is running rampant, people could use this gel as a preventive measure to stop the initial infection."

Doctors in the US have made medical history by effectively curing a child born with HIV, the first time such a case has been documented. The infant, who is now two and a half, needs no medication for HIV, has a normal life expectancy and is highly unlikely to be infectious to others, doctors believe.
