"The research has been conducted by the research group of professor Walter Doerfler at the Intitute of genetics, Dept. of Medical Genetics and Virology at the University of Cologne. Formerly the group has reported that DNA survives transently and enters the bloodstream of mice (Schubbert R, Lettman C, Doerfler W, Mol Gen Genet 242:495-504).
In that study they could demonstrate that pieces of ingested foreign (M13 bacteriophage virus) DNA of the size of 200-400 bp (base pairs) were found in the feces of mice 1-7 hours after intake.
In the bloodserum and blood cells, M13 virus DNA was found between 2 and 6 hours after feeding.
Prior to feeding no such DNA was found in the blood or feces.
The study used state of the art analysis methods and was carefully controlled.
In a second study reported by the Doerfler group at the Congress on Cell Biology in San Fransisco in dec 1996, they had replicated and extended the above study. They found, in the feces of mice large enough pieces of ingested M13 DNA to contain a gene. Furthermore they used a molecular probae to find out if the ingested M13 DNA could enter the cells. The probe was a dye molecule prepared to light up only when it binds with M13 DNA. They found that this probe lit up not only in the intestine but in the spleen, white blood cells and the liver. In some cases as much as one cell in a thousand had viral DNA. They found that this DNA had been ejected, after 18 hours from most cells. But Doerfler speculated that occasionally some foreign DNA may remain. See R. Schubbert, D. Renz, B. Schmitz, and W. Doerfler.Foreign (M13) DNA ingested by mice reaches peripheral leukocytes, spleen and liver via the intestinal wall mucosa and can be covalently linked to mouse DNA. Proc. Natl. Acad.Sci. USA 94, 961-966, 1997. A brief resumé of this study was reported in New Scientist, 4 Jan 1997.

The V-gurt and T-gurt stories are quite true. I have read and passed a long several reliable articles that have documented Monsanto's manipulation of the poorer farmers of other regions. Telling these folks the seeds would produce great crop, yet never produced as they said or were viable for replanting. I recently over heard a conversation at a local restaurant from a farmer talking about "critter and weed resistant" seed from Monsanto. There's a reason the critters don't want anything to do with those crops.
