Smallpox From The Past
An anonymous reader submits "Earlier this year, librarian Susanne Caro was looking through an 1888 book on United States Civil War medicine and discovered a small envelope labeled 'scabs from vaccination of W.B. Yarrington's children' and signed by Dr. W.D. Kelly, the author of the book. After a bit of research, she realized they might be smallpox scabs used in early live vaccination methods and contacted various officials including the Centers for Disease Control and Prevention. The CDC was excited by the find, because it gives them an untreated specimen from over a century ago, and a chance to look at the disease's evolution. Although the FBI had concerns that the smallpox may have been planted in the book, most of the researchers believe the scabs are too old to be dangerous, and they fear they may not even be able to yield live smallpox."
Sounds creepily like the beginning of a Robin Cook novel...
Because I would hate to contract small pox just for working during a strike...
Ok, the FBI thinks someone planted smallpox, in an envelope LABELLED with biohazard information, in a 19th century book, in Santa Fe. What the hell is wrong with them? I mean, that's just moronic.
is this a bad thing?? I'd feel better knowing that no remnants of the virus were able to survive that long.
About the only time you will find scabs in a book and be excited about it. Mostly you'd say "Ok, I'm only going to buy NEW from now on".
graspee
It's largepox you should be afraid of.
One more reason to have the government tightly control what books you check out.
Libraries are a breeding ground for terrorists, I tell you.
Hey, are these raisins? *munch*
Pelé!
From the article:
the envelope rests in a freezer at the Centers for Disease Control and Prevention in Atlanta, awaiting a battery of tests.
Yes, after lying in a library book for 115 years I can see why is important that it be frozen now.
What a wonderful idea for a time capsule that would be. Create a time capsule to be opened in hundreds or thousands of years and place in it some of the diseases which may have died off by then and which the generations of the future will not have had the chance to enjoy.

Yep. With all that Arab oil money they are funded with, al Qaida has invented a time machine, gone back to 1888, and planted smallpox in a book they know some woman in the future will pick up and read.
People say I'm crazy, I got diamonds on the soles of my shoes...
Virus represent the border between living and dead matter. I thought that it meant that when the virus came across a host cell it could inject its DNA and multiply and that is why it is living , and when it didn't it just lay dormant i.e. it was dead matter. Wasn't the whole premise of Jurrasic Park based on this notion ?
But in the article it says ....
If the virus is nothing but the DNA and a protein coating around it, why are the people wanting it to be live ?
Am I missing something ? What am I missing ?

I guess the World Health Organization's crowing about smallpox eradication was a bit too early!
Great minds think alike; fools seldom differ.

They are probably referring to whether or not the DNA information is sufficiently in-tact. If the DNA is too far destroyed, the virus probably won't be able to reproduce itself even after infecting a live cell.

*beware the cute-bunny virus
In this context, "live" virus is able to infect and reproduce. "Killed" virus has been damaged to the point that it cannot infect a cell. Hence the concern over using "live" virus vaccines - the vaccines use a damaged or weakened virus that the body can easily defeat - but occasionally a few full strength particles get through and trigger the disease instead of vaccinating against it. "Killed" virus vaccines use fragments of destroyed viruses, ensuring you can't get sick from them, but possibly not as effective as the live kind.

I think they just mean viable, not really "live", since "live" has a weird meaning for a virus. If they couldn't find live virus samples, then either the virus wasn't there, or it was, but is now "dead", in the sense that it can't work anymore.
True, viruses are just dna and protein, or something like that... Collections of complicated chemicals, basically. They can still degrade, given enough time. Heat them up enough, they will "die", by having their molecules scrambled, etc...
But, IANAChemist, nor a biologist, so take my words with a grain of salt.
There's also a slim chance, researchers say, that the scabs could yield live smallpox virus -- believed to reside in only two laboratories in the world
Only the naive believe that live smallpox exists in only two labs in the world. A more accurate statement in the article would have been "only legally allowed in two labs in the world."
There is strong reason to believe that North Korea has the virus. France is also believed to have it. Iraq may have had it up until recently, as it was endemic in the region in the late sixties, and just a few scabs in a refrigerator would have been enough. It used to be common practice for scientists and doctors to keep a bit of smallpox in the fridge when they gathered it from patients. Hence there could be samples, possibly not even labelled or known to the owners, in a number of places in the world.
One reason that the plan to destroy all stocks at the CDC and the official Russian lab was the realization that rogue countries probably had the virus, and hence destroying it would damage future defense attempts.
Furthermore, the USSR and later Russia maintained stockpiles of 20 tons of weaponized smallpox in the eighties (authorized by Gorbachev) and probably to the present, and loaded it into missile warheads. Furthermore, a number of their scientists have since emigrated to other countries. In 1994 a number visited North Korea for unknown reasons. One former Soviet BW officieal entered into a deal with Iraq to sell 5000 liter fermenters.
And then we have accidental discoveries like these scabs. Smallpox can survive in scabs for a long time, although >100 years is stretching it.

Well, I am a Biologist and your answer is right!
The basic unit of life is the cell. Anything subcellular is not considered "alive" by scientific standards.
-DD
Tom Ridge will claim that we now need to ban books in order to be more "secure".
The FBI needs to get a life if they were at all concerned about this. How embarassing. Morons. Everything is "terrorism" until proven otherwise. My god.

It's a widely believed fact that bioweapons and extensive use of tactical nuclear weapons will be used in WWIII that is due to begin in 2006-2007.
Russia, China and the Arabs will unite. New York will be devastated by two small nuclear devices and while USA isolates itself to deal with the trauma, China invades Asia and Russia pushes into Western Europe.
Could you pin down the dates a little more, old chap? I need to get my planning in order and know when to go hide.
Thanks!

Don't worry, this is the FBI which has made short shrift of Osama bin Laden, singlehandedly captured Saddam Hussein, cornered the Anthrax Mailer, cleverly foiled the 9/11 planebombings on advance intelligence, have kept Chinese industrial spies away from our tech secrets, has won the drug war, busted the thieves at Enron, WorldCom, Global Crossing, Arthur Anderson, and the rest. They found the malicious Bush leaker who blew CIA agent Plames cover in Niger, discredited the 16 State of the Union words about the imaginary African uranium bound for Iraq, preempted Iranian and North Korean nuclear bombs. They nabbed the 2000 election vote riggers, and are already jailing the criminals at the top of the 2004 eVote insecurity debacles. If they think something is scary, we should all bow our heads in fear, and double their budget again. If it were possible to promote the FBI chief, we would; instead, we'll just have to settle for the Patriot Act, which dissolves that archaic Bill of Rights which was just getting in the way.

welcome are new FBI overlords.
Seriously, this was probably a routine chit chat thay have when enybody discovers something like this.
I'm sure they new full well it wasn't a real issue. otherwise it would have been VANS of FBI agents.
The Kruger Dunning explains most post on
the FBI had concerns that the smallpox may have been planted in the book
In a related story, the authorities are now scouring libraries coast to coast to find the book entitled, "Where I Am Hiding" by Osama Bin Laden.
Also, a biologic agent takes hours if not days to act, allowing for retaliatory strikes, so a biologic ICBM is clearly a kind of Doomsday Machine -- what is to say that the smallbox doesn't spread back to Russia. And you have such a Doomsday Machines, in the words of Peter Sellers, why don't you advertise it to the whole world? What good is a Doomsday Machine that you keep secret?
First, I think if they can get any DNA out of it, that would be nice. If they mostly (at least supposedly) want to study the evolution of the virus, I'm sure they can garner some information just by comparing the DNA sequence of whatever they pull out, vs. the "current" stock. Of course it's always best to get the whole genome, but there will almost always be highly conserved (having a very low mutation rate) DNA regions. In organisms with large genomes, you can often compare those against each other to study the amount of divergence.
...
... I'm slightly confused. If the latest vaccine used was cowpox-based, are they trying to study the similarities between now-cowpox and then-smallpox? I can see them wanting to understand how a virus has evolved, but I don't see what exactly comparing it to cowpox would do. Perhaps they want to study how the two have diverged. Any thoughts?
Second
"This could lead to a greater evolutionary understanding of the smallpox vaccine we're using in the U.S.,"
Hm
The floggings will stop when morale improves.
AIAAD (Actually, I am a doctor). In fact, my specialty is Infectious Diseases.
By 1888 vaccination against smallpox using cowpox or vaccinia virus was a common practice, as opposed to "variolization" (inoculation with actual smallpox virus, aka variola virus), since the former was so much safer. This is touched on only briefly in the Washington Post article. So even if there is viable virus in the scab, it may not be smallpox. For reference see the first part of this chapter.

Am I missing something? What am I missing?
As a card-carrying virologist let me give you a run down on the information you're missing. If you don't consider the type of nucleic acid (RNA or DNA), there are two types of viruses that infect mammalian cells - enveloped and non-enveloped. Enveloped viruses (such as smallpox) have an outer lipid bilayer (the envelope) that is studded with glycoproteins that need to bind specific molecules on the surface of mammalian cells to permit fusion between the viral envelope and the cell membrane. Fusion allows the virus' nucleic acid to enter the cell. The viral envelope is very fragile, and breaks down rapidly when dried. When the envelope breaks down, it spills the contents of the virus out -- i.e. the nucleic acid, which in the absence of the envelope doesn't have a means to specifically enter a cell. This is one reason why wiping surfaces with 100% ethanol (a dehydrating agent) is quite effective against enveloped viruses like HIV.
Even viruses that are not enveloped have protein coats that directly interact with cell surface molecules that act as receptors to mediate the entry of these viruses into cells. The proteins that make up these coats also denature (lose their proper shape) with time, although this is typically a slower process.
Finally, how stable is the viral nucleic acid? Viral nucleic acids are typically not present as naked RNA or DNA, but in a complex of DNA or RNA with proteins that coat them. These coated nucleic acids are quite stable. Nucleic acid from DNA viruses (like smallpox) is likely to be more stable than nucleic acid from RNA viruses, and I'm guessing that they should be able to do phylogenetic studies on the strain of smallpox present in those scabs after amplifying recovered DNA by PCR.
BTW, after many years of Slashdot lurking, a wee bit of horn tooting. My lab works on how the genome of EBV latches on to human chromosomes. Here's a pretty picture from our work that was on the cover of the Journal of Virology last month.
What is really needed now is a moderation option called "Eeewwwww!"
