US scientists have developed a vaccine for an inhaled form of the lethal toxin Ricin.

A team at the Walter Reed Army Institute of Research found all mice with a vaccine rubbed into there skin survived after inhaling the toxin.

Ricin, produced naturally from castor beans, is 6000 times more poisonous than cyanide and is fatal in tiny amounts.

The findings were presented at the American Society for Microbiology's Biodefence Research Meeting.

Full Story




Here is some more information on Ricin and its recent news about it.

Looks like the CDC and USAMRIID have been busy with its other companies.

Here is some more information on Ricin, who can use it and how simple it can be to make and come across it.

The links are from various sources on the web and the first one is a special report from the guardian.

Special Report

Background on Ricin

Symptoms of Ricin Poisoning

Hope this covers the main parts...there is other links on these websites so more information is available.

Almost impossible as the ricin lethal interaction with human body cells is very specific and it is not just another poison.

Lectins (from the Latin legate, to pick or choose) were first identified in 1888 by Stillmark at the University of Dorpat in Estonia. While investigating the toxic effects on blood of castor bean extract (Ricinus communis) he noticed that the red cells were being agglutinated. He isolated the material responsible for the agglutination and called it ricin. Shortly afterward at the same university Helfin discovered that the toxic extract of the seed Abrus precatoris also caused cells to clump together. This new agglutinin was called abrin. This immediately caught the attention of the German bacteriologist Ehrlich who recognized that he could investigate certain immunologic problems with them rather than the then popular bacterial toxins. With these two agglutinins some of the most basic principles of immunology were discovered, such as antibody specificity and species specificity. In 1908 Landsteiner reported that small amounts of lentil lectin would agglutinate rabbit erythrocytes, even high concentrations of the lectin had no effect on pigeon red cells.

The 'blood type diet' was based on that discovery.
