The bottom line is that external genetic material is introduced into the host cells (say, GM corn grain) by means of either specially crafted viruses, called viral vector, or bacteria like E-coli that assimilate well foreign DNA, carrying the genes in question precisely because virus has the ability to reproduce and invade other organisms (and bacteria multiply exponentially) — otherwise viruses would be useless.
The increased virulence of E-coli epidemics (and infections in general) in the 20th century could have been caused by such specially crafted bacteria.
Now, if such virus or bacteria escape or are released from the lab (so that the Big Pharma can later make huge profits from selling vaccines) no-one knows what harmful effects it can have on humans, since these artificial organisms are totally unfamiliar to our immune system.
‘Genetic engineering is used to create animal models of human diseases.(I don't believe anything achieved through torturing living creatures can be really beneficial for humans).
Genetically modified mice are the most common genetically engineered animal model. They have been used to study and model cancer (the so-called onco-mouse), obesity, heart disease, diabetes, arthritis, substance abuse, anxiety, aging and Parkinson disease, to name but few. Potential cures can be tested against these mouse models. On top of it, genetically modified pigs have been bred with the aim of increasing the success of pig to human organ transplantation',
Anyway, a few will be “cured” and millions killed.
Even though all these vague hypothetical benefits became real one day, the problem is that it's humans who work in the labs, and humans make mistakes (not to mention all the evil purposes these technology could be used for), so there's enough likelihood, additionally backed up by my lifelong observations, of a virus escaping from a lab to stop me from sharing gung ho technologists’ peace of mind. You see, it's just a question of common sense, but someone rightly said that sense isn’t common.
Several instances reportedly occured in some communist countries (apparently in mid sixties), which of course was never made public.
What I never managed to figure out is where viruses actually come from. Hepatitis B, HUSL, HIV, etc.
As an aside, wild as it sounds, I start to suspect human body (the first host) itself produces viruses and then passes them on to other humans, the same probably being true for plants and animals. A piece of DNA detaches from the host for some unaccountable reason, moves on to become a virus for another unaccountable reason, and then jumps from host to host.
Here’s a little insight into the technique and its potential.
Lee et al. (2002) reported using genetically engineered M13 bacteriophage viruses to create quantum dot biocomposite structures. As a background to this work, it has previously been shown that genetically engineered viruses can recognize specific semiconductor surfaces through the method of selection by combinatorial phage display. Additionally, it is known that liquid crystalline structures of wild-type viruses (Fd, M13, and TMV) are adjustable by controlling the solution concentrations, solution ionic strength, and the external magnetic field applied to the solutions. Consequently, the specific recognition properties of the virus can be used to organize inorganic nanocrystals, forming ordered arrays over the length scale defined by liquid crystal formation. Using this information, Lee et al. (2000) were able to create self-assembled, highly oriented, self-supporting films from a phage and ZnS precursor solution. This system allowed them to vary both the length of bacteriophage and the type of inorganic material through genetic modification and selection.
