Giant Marine Virus Found
…these viruses, which appear to obtain much of their large genomes from their hosts and other microorganisms, may be more commonplace than scientists once believed.
… Not only can viruses take up genetic material from their hosts and other organisms, but they can donate genes, as well

In light of the findings, Scheuermann cautions against attempts to develop universal vaccines that work against different strains of flu viruses year after year, because they could generate destructive antibodies. Instead, the results may prompt doctors to treat middle-aged flu patients with drugs that inhibit the formation of antibody-pathogen complexes, he says, adding, "Now that we have an understanding of the mechanism of severe disease, we'll be in a much better position to treat infected people and prevent them from dying."
Scientists at the 234th national meeting of the American Chemical Society in Boston, Massachusetts this week presented the results of a study that suggests a common virus could be partly responsible for the obesity epidemic that is sweeping across America and other nations. They hope their findings will develop antiviral medication to treat "viral obesity".
Their research strongly links a common human virus -- adenovirus-36 or Ad-36 -- to human obesity.

Amazing thread, loads to consider. I wanted to share with you an article I found a few minutes ago.
"Exposure to Seasonal Flu Weakened Armor Against H1N1"
I found some of the theories plausible in this report and yet what made me think of you was this:

PS, I got a stay of execution on my DSL and phone, well until December 20th...

It's not discussed much since we "all know" that obesity is caused by weak willpower, but there has been research into a viral cause. This is from 2007, but there have been some follow up articles identifying a specific virus.

I've been wondering for quite a while if the epidemic we've seen in autism spectrum disorder cases could be virus based.

ok ok i k now this is going to sound crazy as hell, but i was just wondering, does this have anything to do with vampires? who knows if vampires are real, i don't know, but we've all heard myths concerning being bitten, surviving, and thereafter turning into a vampire... not sure if that is the 'proper' or 'true' myth to vampires or 'becoming' a vampire but perhaps the process of becoming a vampire is the transfer of the 'vampire' gene to the person being bit, similiar to the virus in the OP transfering / altering some of it's host's genes/dna
haha hope that wasn't too over the top, i'm not a 'vampire fanatic' nor have i seen those twilight movies everyone's talking about, but for some odd ass reason this post made me ponder that idea!!!
FDA OKs bacteria-eating virus to treat meat
WASHINGTON — A mixture of six bacteria-killing viruses can be safely sprayed on meat and poultry to combat common microbes that kill hundreds of people a year, federal health officials said Friday.
The mixture of special viruses, called bacteriophages, would target strains of Listeria monocytogenes, the Food and Drug Administration said in declaring it is safe to use. The viruses are designed to be sprayed on ready-to-eat meat and poultry products just before they are packaged.
On November 17th, President Obama presented 10 researchers with the highest technical and scientific award given by the United States, the tNational Medal of Science.
Susan Lindquist, Massachusetts Institute of Technology, for showing that changes in protein folding can have profound and unexpected influences in fields as wide-ranging as human disease, evolution and nanotechnology, and for providing fundamental experimental support for the prion hypothesis. The prion hypothesis is a key scientific assertion associated with a group of progressive conditions that affect the brain and nervous system of many animals, including humans.
A prion is short-hand for proteinaceous infectious particle. Prions are infectious proteins thought to cause disease as viruses do (prions are misfolded, misshapen, proteins). The key difference between a prion and a virus is that prions lack the DNA or RNA that forms the command structure of a virus. Prions have been implicated with a number of diseases...
The prion proteins contradict a central tenet of molecular biology: that genes affect proteins, but proteins do not affect DNA.
What Are Prions?
I've been thinking if viruses are infact kind of "updates" to our code. Well, updates in best case, downgrades are not excluded in my opinion.
en.wikipedia.org...]
A bacteriophage (from 'bacteria' and Greek φᾰγεῖν phagein "to eat") is any one of a number of viruses that infect bacteria. Bacteriophages are among the most common biological entities on Earth.[1] The term is commonly used in its shortened form, phage.
...Phages are estimated to be the most widely distributed and diverse entities in the biosphere.[2] Phages are ubiquitous and can be found in all reservoirs populated by bacterial hosts, such as soil or the intestines of animals. One of the densest natural sources for phages and other viruses is sea water, where up to 9×108 virions per milliliter have been found in microbial mats at the surface,[3] and up to 70% of marine bacteria may be infected by phages.[4] They have been used for over 60 years as an alternative to antibiotics in the former Soviet Union and Eastern Europe.[5] They are seen as a possible therapy against multi drug resistant strains of many bacteria.

Bacteriophages - or phages - are viruses that kill bacteria. They were used successfully to treat infection in the 1930's - but then were upstaged by penicillin. Something of a medical conspiracy arranged to kill the growing industry in natural phages, and replace it with an antibiotic industry, starting with penicillin. Only Russia maintained their phage stocks.
Now - almost all bacteria are resistant to antibiotics, and most now just mutate immediately when they're exposed to antibiotics. The situation is dire - making simple infections potentially deadly once again, and affecting the safety of surgery.
So out of necessity - scientists are looking at phages again. Just tripped over this PubMed citation:
Antimicrob Agents Chemother. 2005 Nov;49(11):4789-92. Therapeutic Effects of Bacteriophage Cpl-1 Lysin against Streptococcus pneumoniae Endocarditis in Rats. Entenza JM, Loeffler JM, Grandgirard D, Fischetti VA, Moreillon P. Department of Fundamental Microbiology, Biology Building, University of Lausanne, CH-1015 Lausanne, Switzerland. [email protected].
Cpl-1, a pneumococcal phage lytic enzyme, was tested in rats with experimental endocarditis due to Streptococcus pneumoniae WB4. High-dose regimen Cpl-1 eliminated pneumococci from blood within 30 min and decreased bacterial titers in vegetations (>4 log(10) CFU/g) within 2 h. Rapid bacterial lysis induced by Cpl-1 treatment increased cytokine secretion noticeably.
