Are there any such thing as good virus?
« on: 13/11/2015 20:05:08 »
If you look at bacteria, the one's that live in the gut of humans, help our digestion and are part of the immune system. These are good bacteria; probiotics. This is in contrast to bad bacteria that do harm and need medical care.

The question I have is; are there also good virus and not just bad virus? For example, how about easy for the body to control virus, that are designed to help exercise our immune system, with little if any long term negative side affects? Practice would be helpful for the immune system.

Virus can insert genes, so how about virus whose genetic insertion, helps the host DNA by adding a new genetic spin to existing genes? Ticks don't seem to mind Lyme Disease virus. Is this because the genetic spin make them immune?

Or as an alternative, could part of DNA, behave like virtual viral DNA, so these good genes can be mass produced internally, and then spread externally to others, with a sneeze?

We benefit from several genes that were introduced by viruses (and bacteria) http://news.sciencemag.org/biology/2015/03/humans-may-harbor-more-100-genes-other-organisms

A viral gene embedded in the sheep genome plays an essential role in the growth of the animal's placenta, according to a study of impregnated sheep. The result strengthens the case that similar viral genes play the same role in mice and people.

Bacteriophages are viruses that attack bacteria.

They tend to be very specific to one target bacterium, so if you are suffering from a bacterial infection, a corresponding bacteriophage could potentially get it under control. This avoids the negative side-effects of broad-spectrum antibiotics on "friendly" bacteria in the gut.

Bacteriophages have been used this way in the Soviet Union.
