Direct from DNR Court Case Testimony:
After feeding three deer "repeated 90 daily oral doses of urine and feces from CWD positive source deer" the deer did not test positive after 12 months!
By Dr. Miller: (Blood)
A. This particular piece of work showed that
1 infectivity was present both in salivary secretions
2 from the infected deer. In this case they were
3 using whitetail deer and also infectivity was
4 present in blood.
5 Q. Were you a co-author of this paper as
6 well?
7 A. I was. I had more of a minor goal on
8 this particular paper than I did in the paper that
9 we just discussed, the Tamguney paper.
By Dr. Miller: Crows
21 Q. I've seen some reference in the case to
22 transmission from crows who have ingested feces
23 from deer and that being a possible vector of
24 transmission. Are you familiar with any of that
25 research?
1 A. Unless there has been one that I have
2 missed, there was a paper that came out maybe a
3 year or so ago, plus one I believe, and it was
4 actually crows that were fed brain tissue from
5 mice, I think, mouse-adapted scrapie, which is,
6 again, another model and I believe they were
7 looking at the feces from the crows is what you are
8 thinking about in terms of transmission.
9 So it's kind of a pass-through
10 transmission. I don't believe in that paper that
11 there was any suggestion that the crows would
12 propagate infectivity but they could serve as kind
13 of a feathered vehicle for maybe physically moving
14 it around during the period of time that the
15 material was ingested.
them.
Dr. Waldrup - Feces and Urine Study
25 Q. If you look at his article a little bit
662
1 further down, he concludes that CWD is not highly
2 contagious, is that true?
3 A. In the context that he is using it, yes,
4 it would be true.
5 Q. What do you mean by that?
6 A. When -- just a second. Oftentimes when
7 we talk about a highly contagious disease this is a
8 disease which a large part of the population
9 becomes either antibody reactive or actually become
10 sick and any human influenza is a good example of
11 this. If only 10 percent of the population becomes
12 infected that's not really a highly contagious
13 disease. It is contagious.
14 And that's been shown. CWD is contagious
15 but I guess it comes down to a matter of
16 perspective when you say highly contagious and to
17 me the numbers compared to other diseases of deer
18 for CWD transmission is not highly contagious.
19 Q. Now, could you please turn to Exhibit
20 MMM. You've heard some testimony about the
21 transmission of CWD through the discharge of fecal
22 material. What does this study indicate about
23 that?
24 A. Well, if you will look at the figure on
25 page 6 of the article, when the researchers in this
663
1 tried to lead to urine and feces, PO.
2 JUDGE PALMER: PO?
3 A. And that stands for P-E-R-O-S, PEROS,
4 that's an oral administration. You can see very
5 clearly they could not transmit it at all.
6 Q. How long of a period of time had they
7 been trying to transmit it?
8 A. Well, back in the methods and materials
9 here. For urine and feces each of the three deer
10 received repeated 90 daily oral doses of urine and
11 feces from CWD positive source deer.
12 Q. How long were they measuring to see
13 whether or not the deer --
14 A. Up to 12 months, as I understand it.
15 Q. If you turn to Exhibit TT.
16 MR. GALLAGHER: Move for the admission of
17 Exhibit MMM at this point.
18 JUDGE PALMER: Any objection? MMM is
19 admitted.
20 Q. How does this study, Exhibit TT?
21 A. Yes, I have it.
22 MS. BROMMEL: Just TT, not TTT.
23 JUDGE PALMER: All right.
24 Q. And this study is by Tamguney, correct?
25 A. Yes.
Q. And how does this study's finding compare
2 with Exhibit MMM?
3 A. It has already been pointed out the
4 recipient animals in this study were transgenic
5 mice. The recipient animals in the Mathiason
6 article before were actually whitetail deer.
7 Q. Why was that significant?
8 A. We are concerned about this in deer.
9 Again, Dr. Miller stated very, very, well by the
10 use of transgenic mice is convenient but a
11 transgenic mouse is not a deer.
12 Q. So in the study that actually focused on
13 deer they couldn't transmit it or they found out it
14 was not transmitted over the course of 12 months?
15 A. Correct.
