Just how little BSE in feed will result in transmission?

Experimental BSE Oral Attack Rate Study

An oral attack rate study in cattle (Dawson 1993) provides some insights. The study used untreated brain material from a pool of brains derived from cattle with clinically confirmed BSE. Groups of cattle were exposed to four different treatments regimes:100g of untreated brain material given orally on three occasions, or 100g given on one occasion; 10g given on one occasion; or 1g given on one occasion. The infectivity titre of the brain pool used in this study was about i/c ID50/g (refer to Appendix 2 for explanation); Dawson et al., 1993; Wells et al., 1994, 1996, 1998, 1999.

All four groups developed the disease. The attack rate was not 100% in the two low-dose groups (1g and 10g) and the incubation period was longer than in the high dose groups. It can be concluded that 1g of brain with an infectivity titre of 10 x 3.5 i/c ID 50g is probably not a limiting oral dose for cattle.

Now who's hallucinating Reader. :) :)

While you're at it folks, why not find the undisputable proof that vCJD is caused by humans eating bovine products from a BSE "infected" :) :)

All we'd have to do is find a willing person to eat some infected material and observe them in a clinical trial to satisfy the nay-sayers.

Anybody know of a volunteer? :???: :???: :???:
 
Mike- "All we'd have to do is find a willing person to eat some infected material and observe them in a clinical trial to satisfy the nay-sayers.

Funny you should mention that Mike. How many BSE positive cattle in the UK entered the human food chain prior to the big BSE scare? The SRM's were not removed from these (several hundred thousand at least cattle) This "deadly" beef was consumed by tens of millions of people.
If so little contaminated material can cause infection, just why is it that ,to date, only about 150 people have died from vCJD??? OH ya, I forgot. The incubation period. Well this all started PRIOR to 1985. And still only 150 cases of vCJD worldwide, which BTW, have never been proven to be caused by eating beef. Some were vegetarians for Christ-sake!!! How did they catch vCJD?? From sniffing chile-farts??? :D
 
Can you tell all of your fans here on ranchers reader, do all of the studies you mention involve homoginate? And then would you care to describe the homoginate process, or would you like me to do it in my hillbilly way?


You're out to lunch on the Purdey thing reader and you know it. Purdey does not accept the oral transmission theory, the way that you are descibing.

Explain away, Jethro! :lol:
 
Reader
The species barrier appears to be very strong and only breached under certain conditions -- namely in young people of a certain genotype probably with other factors present, such as some inflammatory condition.

Incredible speculatory investigation. This is always a good one to me. Mislead by talking about similarities in the makeup of victims while having no idea as to whether these poor souls even ate beef in their lives.

vCJD is like BSE. That does not mean it came from BSE. Maybe the darn cows got it from eating a dead human for crying out loud. Makes as much sense as this speculative garbage.
 
Sandhusker- "Explain away, Jethro!"

You might want to re-read RK's post Sandhusker. :)

Jethro. PS.

I've already explained that all I'm asking for is that someone post an INDEPENDANT SCIENTIFIC STUDY PROVING THAT BSE CAN BE TRANSMITTED TO A BOVINE BY FEEDING IT A NORMAL ORAL DOSE OF INFECTIVE MATERIAL.

Excerpts from the UK BSE Inquiry and the Horn report are not INDEPENDANT. Monkeys don't count... etc... etc...etc... :D
 
Homoginate is what's left over when the indestructable misfolded prion is broken down into its basic parts mechanically. Something that cannot be done by any normal, natural process within the body of an animal.

Uhm,

Thank you

Send funds for further reseach to RK (Jethro) the crayon man.

Sounds good to me and while you're at it, go find the original description of the maybe 20 DEFRA studies that Mike and I cited and prove that all of them were done using homogenate brain. And prove that this definitely disproves that BSE can be transmitted orally. And then find the studies on the 18 species (as of 1994) that BSE transmits to via ingestion and disprove them all too. Come on, kids, this is getting ridiculous. Intelligent design, indeed.

In fact, In Dawson's research it says:
"Since cattle were never exposed in the field situation to untreated brain material but rather to COOKED AND DRIED BRAIN, IN THE FORM OF MBM, IT MIGHT REASONABLY BE EXPECTED THAT AN INFECTIVE DOSE OF 1 GRAM OF FRESH BRAIN MIGHT NOW BE ACCOMODATED IN A MASS OF ABOUT 0.1 GRAM OF DRIED BRAIN, ASSUMING THAT THE COOKING PROCESS DID NOT PROVIDE ANY INACTIVATION AND THERE WAS NO DILUTION BY MIXING."
 
:D :D :D

And the ONE INDEPENDANT STUDY that I asked for is WHERE???? :D


I also noticed a few "is thought to be's" etc. in there.Funny that you are still quoting USDA scientists as gospel even as you question them in other threads...Who is full of it???

How hard can it be R2??? ONE INDEPENDANT STUDY WHICH DEFINITELY PROVES THAT BSE CAN BE TRANSMITTED TO BOVINES THROUGH FEED. ONE. ONLY ONE. :lol:

Give Up. Such a study does NOT exist! If it did, you would have posted it by now. :D
 
Jethro, You are showing your ignorance now. I have GOT to sit you down and have a long talk with you. :wink:

All of the studies, Dawson, Wells, etc. are available for a fee of $25. Please forward your credit card number and I will order the WHOLE DAMN STUDY for you. I'm just not convinced you can read them.

You turd! 8)

OH!! OK Mike. My credit card number is 13 I think!! :roll: Surely if a study such as I am asking for exists, it should be very easy for you or R2 to post it here for every one to see. What's the friggin' hold up???

Who are you callin' a turd ,you sleazy skydiver???

The world of the conspiracy theorist.

If it "APPEARS" as fact, if it "RESEMBLES" fact, if it "COULD BE" fact, if it "MIGHT BE FACT", if "WE THINK IT'S FACT", if it's "POSSIBLY FACT", then it becomes fact.

Haven't you figured that out yet Tim?

When you want to believe something bad enough, "MIGHT BEs" transform into fact right before your very eyes.

Conspiracy theorists will believe anything that resembles the truth if it's what they want to believe.



~SH~
 
TimH- I agree that you've made your point that their are many many unanswered questions about BSE and its transmission--too many for the USDA to be pooh poohing it and lowering our import and BSE firewall standards.....We need to let the scientists work on it and some of these studies that are in progress run their course before any Border openings......
 
The independent peer reviewed studies are there for all to see if you are willing to pay for them. The abstracts are proof enough for those interested in the truth.
