The venom from a bee may be utilised in the prevention of HIV (wallpapersus.com)

The sting of a bee could provide a breakthrough in the fight against HIV infection.

Toxins in the insects' venom can destroy the virus and leave surrounding cells unharmed, suggest research studies.

Scientists believe it is an important step towards developing a gel to stop the spread of the HIV virus, which causes Aids.

The principal ingredient of bee venom, melittin, 'drills' a hole in the virus envelope, and disables it by essentially skinning it alive.

Researchers inserted the toxin into tiny nanoparticles fitted with special 'bumpers' so they can bounce off normal cells.

When the smaller HIV virus makes contact with them, it slips between the bumpers and is attacked by the toxin.

Study expert Dr Joshua L Hood, of Washington University School of Medicine, said the toxin could be used in a vaginal gel to prevent HIV spreading.

He 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."

Most drugs slow the growth of the virus, but the bee venom attacks and kills it to prevent infection in the first place.
