Bacteria in Yogurt Modified to Fight HIV Infection
Bacteria in yogurt have been modified to deliver a drug that blocks HIV infection.
In their natural state, the bacteria (Lactococcus lactis) produce lactic acid and are used to make cheese and yogurt. It is not harmful to humans.
Research based at Brown Medical School in Rhode Island altered the genetics of the bacteria so they generate cyanovirin, a drug that has prevented HIV infection in monkeys and human cells, according to a report at news@nature.com.
Cyanovirin binds to sugar molecules that are attached to the HIV virus, blocking a receptor used by HIV to infect cells.
"It's basically passive immunization," said Sean Hanniffy, a member of the research team from the Institute of Food Research in Norwich, UK.
Cyanovirin could be put into gels that women would apply to the vagina before sex. Or, an oral dose might provide long-term protection, the researchers speculate. They note that there could be public resistance to the whole idea of genetic modification.
The work has only been proved in a lab setting, however. Human trials could begin in 2007.
Well thats pretty interesting hehe, apple a day keeps the doc away, and now Yogurt could keep HIV away

I dont have any issues eating modifid food personl. I rather eat gentically modifid food over food with chemicals in it.

Jeff ******* says (9:19 AM): Eww, Ottawa is gross. It's infested with politicians, and presently, 1 Harper as well.

Interesting. I wonder how they deal with the rapid mutation rate of HIV?
Though, way to go yogurt!

Oh dear. Did they learn nothing from the BSE thing? Mess with the food supply and there's gonna be major unforeseen problems somewhere down the line, simple as that.
The best way to avoid HIV is to not be a druggie and not shag everything that moves. Easy really.

Been inclined to wander... off the beaten track.
That's where there's thunder... and the wind shouts back.

Certain yogurts with live and active culture helps my sour stomach most of the time.
Preventative.

I would think putting yogurt down there would be uncomfortable....

I think this article is the media distorting things until it hardly makes sense any more. Bacteria have been genetically modified to produce drugs since a long time. Human insulin for example is produced by bacteria since the seventies. Of course diabetics don't inject the bacteria themselves, they just use the produced insulin like any other normal (chemically produced) drug. This news sounds like in this case lactobacilli have been modified to produce a drug, but of course nobody would use those to make yoghurt.
