Atypical Prion Diseases in Humans and Animals

Michael A. Tranulis, Sylvie L. Benestad, Thierry Baron and Hans Kretzschmar

Abstract

Although prion diseases, such as Creutzfeldt–Jakob disease (CJD) in humans and scrapie in sheep, have long been recognized, our understanding of their epidemiology and pathogenesis is still in its early stages. Progress is hampered by the lengthy incubation periods and the lack of effective ways of monitoring and characterizing these agents. Protease-resistant conformers of the prion protein (PrP), known as the “scrapie form” (PrPSc), are used as disease markers, and for taxonomic purposes, in correlation with clinical, pathological, and genetic data. In humans, prion diseases can arise sporadically (sCJD) or genetically (gCJD and others), caused by mutations in the PrP-gene (PRNP), or as a foodborne infection, with the agent of bovine spongiform encephalopathy (BSE) causing variant CJD (vCJD). Person-to-person spread of human prion disease has only been known to occur following cannibalism (kuru disease in Papua New Guinea) or through medical or surgical treatment (iatrogenic CJD, iCJD). In contrast, scrapie in small ruminants and chronic wasting disease (CWD) in cervids behave as infectious diseases within these species. Recently, however, so-called atypical forms of prion diseases have been discovered in sheep (atypical/Nor98 scrapie) and in cattle, BSE-H and BSE-L. These maladies resemble sporadic or genetic human prion diseases and might be their animal equivalents. This hypothesis also raises the significant public health question of possible epidemiological links between these diseases and their counterparts in humans.

We know so little about CWD. I would like to see some more studies on the effects on humans if there are any. This is the first indication that I have seen that CWD has been linked to human consumption of deer meat. I am sure that we will see more on this in the near future. Or hopefully we will.

Sarge, I've seen two around home over the years that fit the description of CWD. I also had a crop damage permit one summer and killed several with big bare spots on the hide and a strange blue tint to the hide. I was afraid to touch them, much less use the meat. I called our friends in DNR and couldn't seem to get too much response. This was in the days between Jerry and today Mike.

Our biologists have always said that CWD is not a danger to humans but I don't think that enough is known to make a positive statement like that when you are dealing with a human life. People always asked me when I was a Conservation Officer the same question and I told them I was not 100% sure that it could not be transmitted because I didn't think that enough was known about it. It seems now that what I was saying might have had some merit to it.

Let's have a massive, unnaturally dense deer population (any less and a boatload of hunters will claim there are no deer left and rail on the Wildlife Dept.), some huge bait piles, deny there is a problem and that we might be contributing, and see what happens. Great plan.

Sarge01 - Your answer is spot on. There has only been one known and documented case of human consumption of CWD infected venison, and that was with one of the first deer that was tested and confirmed to have CWD in NY. Apparently the meat from the deer was donated to some kind of banquet because the deer looked to be in good health when it was sampled. When the test results came back positive for CWD, a researcher from Binghamton University in NY immediately seized the opportunity to monitor the consumers' health for several years following exposure. Since we really don't know how many people consume CWD infected meat, it will be necessary to monitor states where the disease exists in prevalence. These prion disease have been known to cross species boundaries in the past, so designating them as a "non-threat" to humans seems irresponsible.

Bioguy01,
The deer was donated to a Volunteer Fire Dept. and it was ground up and chili was made from the whole deer. From the report that I read over 300 people ate the chili that the infected meat was made with. I never heard if anyone had any effects from it later on in years. That has been probably 10 or 15 years ago I think. The deer came from a deer farm. That is why all the regulations on the deer farms, because they trade and sell deer back and forth all over the United States.

Sarge01 - Yup, that's the case I was talking about. I did a lot of research on CWD in college, and even assisted with CWD monitoring in NY while working for NYSDEC. NY did a great job at containing the disease, and no positive tests have been confirmed since 2005 when it was found. Hunters were not happy with the aggressive harvest that immediately ensued as soon as CWD was confirmed. Unfortunately, it is a necessary step to keep the disease from spreading. The latest research in PA shows that when young males disperse, they will often travel 5-10 miles, 10-20 mile movements are not uncommon, and at the extreme end they have been known to travel 40+ miles (as the crow flies)! Such movements from infected young deer could really have devastating effects on deer populations that exist in high densities.

I admire that state agencies are monitoring for the disease, but I really think that there are too few samples taken. For disease detection to actually occur, a certain number of animals already need to be infected, and that number will occur in very low prevalence until it starts to spread. NY got lucky and found it in a captive deer. Their aggressive and immediate action found it in a few wild deer. If these actions were not taken, the outcome of CWD in NY might have been similar to Wisconsin, and Wisconsin's experience with CWD has been an absolute nightmare.

Here in WV I was still employed as a Conservation Officer and we assisted the biologist with the kills. In 3 years we sample killed over 300 deer. We found 7 cases in that 300 deer. We set up checking stations for the hunters to check their deer that were killed in the the CWD are. We found 2 cases there. The DNR has enlarged the area considerable in the last 15 years and made drastic regulations for the hunting seasons. Va. right across the border has found affected deer also and Md. which is close to the border has a found an affected animal also. You are right about the travel of bucks and they are known to travel great distances. Was it here all along and we just found it or did it just appear? No one knows. There is so little known about the disease. I am sure you found that out in your studies. Over the past 15 years the DNR has found several affected deer every year. I am afraid it is here to stay. The DNR has put drastic measures in place for the captive deer farms and I feel that is a good start.

It is believed that the spread of the disease has been caused in part by transporting carcasses out of states that are known to be infected. Prions do not break down or die like bacteria or viruses, so improper disposal of infected deer could initiate the disease. Monitoring efforts are very minimal since the cost of monitoring for the disease is pretty high. The problem with minimal monitoring is that if you first discover it in the wild population, chances are elimination of the disease is too late, and efforts need to be geared toward containment. Like I said, NY was lucky to discover it in captive deer first. If I remember correctly, some of the deer in the captive herd were imported from an infected state, and likely they were the source of contamination.

Monitoring efforts have continued in NY, especially in the containment zone, but no new cases were found. PA is next on the hit list. The state Veterinarian already thinks its here, we just haven't found it yet. Based on my research of the subject, I would say that if it's not here now, it will be within the next few years. In PA only 1% of the harvest is tested. Research suggests that 20% of a localized herd would need to be infected in order for initial detection to occur. This is why NY's case was such a fluke! If had not found CWD in the captive deer, they would have never known it was in the state until it was already well established.

Is there a feeding ban in WV by any chance?

There is a feeding ban in the county that the infected deer were found and the counties that surround it. You cannot take whole deer from the infected area. The meat needs to be removed from the carcass or at least that was the case a year or two ago. It was already in the wild herd before it was found in WV. I can't be sure but I suspect it came from a taxidermist that mounted alot of elk and mule deer from out west and threw the waste out back of his shop. The infested deer came within 1/4 mile from that location. It can't be proven but it is my educated guess.

Sarge01 - I would say that you are spot on with your educated guess.

jamesti - When people feed deer, they usually don't think to spread the food out over a large area, rather they put it in piles. This type of feeding forces deer to feed in close proximity to one another where physical contact and exchange of bodily fluids (saliva, urine, feces, etc...) is promoted. It's almost the same effect that happens when you send the kids back to school. You confine them to interact with others in a small area, and within a few weeks everybody in your household gets the flu or whatever ailment your kids picked up at school. Same principle, different species. Food plots are generally a better way to feed deer if herd densities are kept in check. They allow deer to spread out more and interact with each other less, thus reducing the likelihood of disease transmission.

Thank you for your recent letter concerning the publication of the third annual report from the CJD Surveillance Unit. I am sorry that you are dissatisfied with the way in which this report was published.

The Surveillance Unit is a completely independant outside body and the Department of Health is committed to publishing their reports as soon as they become available. In the circumstances it is not the practice to circulate the report for comment since the findings of the report would not be amended. In future we can ensure that the British Deer Farmers Association receives a copy of the report in advance of publication.

The Chief Medical Officer has undertaken to keep the public fully informed of the results of any research in respect of CJD. This report was entirely the work of the unit and was produced completely independantly of the the Department.

The statistical results reqarding the consumption of venison was put into perspective in the body of the report and was not mentioned at all in the press release. Media attention regarding this report was low key but gave a realistic presentation of the statistical findings of the Unit. This approach to publication was successful in that consumption of venison was highlighted only once by the media ie. in the News at one television proqramme.

I believe that a further statement about the report, or indeed statistical links between CJD and consumption of venison, would increase, and quite possibly give damaging credence, to the whole issue. From the low key media reports of which I am aware it seems unlikely that venison consumption will suffer adversely, if at all.

Living in Colorado all my life, I have seen the best deer hunting areas turn to dust from CWD. Cherokee Park, Colorado was the best area for deer I have ever seen...the best. I would see over 100 deer in a morning... easily and many huge bucks just driving into my area to hunt. Now...it's a ghost town. The Colorado DOW has not publicized this fact because it generates it's revenue from licenses. They beleive that CWD started around Fort Collins area and spread up the Poudre Canyon to places like Cherokee Park. I have driven the Poudre Canyon several times recently and have yet to see a deer. It has been completely devestating. In my opinion the best deer hunting in Colorado is west of the continental divide and Southern Colorado

Just curious why Bioguy01 is getting flamed in this conversation? Seems all of his input is spot on, or at least what I know of CWD his information is true. If I could give you +100 for each post Bioguy01 I would.

I don't understand it either because the biologist in the next office from me told me that is the way they thought that the disease was spread also by close contact by the deer herd. I think that the dings are a carry over from another site, just speculating.

Sarge01 - Your answer is spot on. There has only been one known and documented case of human consumption of CWD infected venison, and that was with one of the first deer that was tested and confirmed to have CWD in NY. Apparently the meat from the deer was donated to some kind of banquet because the deer looked to be in good health when it was sampled. When the test results came back positive for CWD, a researcher from Binghamton University in NY immediately seized the opportunity to monitor the consumers' health for several years following exposure. Since we really don't know how many people consume CWD infected meat, it will be necessary to monitor states where the disease exists in prevalence. These prion disease have been known to cross species boundaries in the past, so designating them as a "non-threat" to humans seems irresponsible.

Sarge01 - Yup, that's the case I was talking about. I did a lot of research on CWD in college, and even assisted with CWD monitoring in NY while working for NYSDEC. NY did a great job at containing the disease, and no positive tests have been confirmed since 2005 when it was found. Hunters were not happy with the aggressive harvest that immediately ensued as soon as CWD was confirmed. Unfortunately, it is a necessary step to keep the disease from spreading. The latest research in PA shows that when young males disperse, they will often travel 5-10 miles, 10-20 mile movements are not uncommon, and at the extreme end they have been known to travel 40+ miles (as the crow flies)! Such movements from infected young deer could really have devastating effects on deer populations that exist in high densities.

I admire that state agencies are monitoring for the disease, but I really think that there are too few samples taken. For disease detection to actually occur, a certain number of animals already need to be infected, and that number will occur in very low prevalence until it starts to spread. NY got lucky and found it in a captive deer. Their aggressive and immediate action found it in a few wild deer. If these actions were not taken, the outcome of CWD in NY might have been similar to Wisconsin, and Wisconsin's experience with CWD has been an absolute nightmare.

Sarge01 - I would say that you are spot on with your educated guess.

jamesti - When people feed deer, they usually don't think to spread the food out over a large area, rather they put it in piles. This type of feeding forces deer to feed in close proximity to one another where physical contact and exchange of bodily fluids (saliva, urine, feces, etc...) is promoted. It's almost the same effect that happens when you send the kids back to school. You confine them to interact with others in a small area, and within a few weeks everybody in your household gets the flu or whatever ailment your kids picked up at school. Same principle, different species. Food plots are generally a better way to feed deer if herd densities are kept in check. They allow deer to spread out more and interact with each other less, thus reducing the likelihood of disease transmission.

It is believed that the spread of the disease has been caused in part by transporting carcasses out of states that are known to be infected. Prions do not break down or die like bacteria or viruses, so improper disposal of infected deer could initiate the disease. Monitoring efforts are very minimal since the cost of monitoring for the disease is pretty high. The problem with minimal monitoring is that if you first discover it in the wild population, chances are elimination of the disease is too late, and efforts need to be geared toward containment. Like I said, NY was lucky to discover it in captive deer first. If I remember correctly, some of the deer in the captive herd were imported from an infected state, and likely they were the source of contamination.

Monitoring efforts have continued in NY, especially in the containment zone, but no new cases were found. PA is next on the hit list. The state Veterinarian already thinks its here, we just haven't found it yet. Based on my research of the subject, I would say that if it's not here now, it will be within the next few years. In PA only 1% of the harvest is tested. Research suggests that 20% of a localized herd would need to be infected in order for initial detection to occur. This is why NY's case was such a fluke! If had not found CWD in the captive deer, they would have never known it was in the state until it was already well established.

Is there a feeding ban in WV by any chance?
