ABSTRACT


Prion diseases, also known as transmissible spongiform encephalopathies, are fatal neurodegenerative disorders. Low levels of infectious agent and limited, infrequent success of disease transmissibility and PrPSc detection have been reported with urine from experimentally infected clinical cervids and rodents. We report the detection of prion disease-associated seeding activity (PASA) in urine from naturally and orally infected clinical scrapie sheep and orally infected preclinical and clinical CWD-infected white-tailed deer. This is the first report on PASA detection of PrPSc from the urine of naturally or preclinical prion diseased ovine or cervids. Detection was achieved using the surround optical fiber immunoassay (SOFIA) to measure the products of limited serial protein misfolding cyclic amplification (sPMCA). Conversion of PrPC to PrPSc was not influenced by the presence of poly(A) during sPMCA or by the homogeneity of the PrP genotypes between the PrPC source and urine donor animals. Analysis of the sPMCA-SOFIA data resembled a linear, rather than an exponential, course. Compared to uninfected animals, there was a 2-4 log increase of proteinase K-sensitive, light-chain immunoglobulin (Ig) G fragments in scrapie infected sheep but not in CWD-infected deer. The higher than normal range of IgG levels found in the naturally and experimentally infected clinical scrapie sheep was independent of their genotypes. Although analysis of urine samples throughout the course of infection would be necessary to determine the usefulness of altered IgG levels as a disease biomarker, detection of PrPSc from PASA in urine points to its potential value for ante-mortem diagnosis of prion diseases.

now, what about those 'deer scents' of 100% urine', and the prion that is found in urine, why not just pass the prion with the urine to other deer...

Mrs. Doe Pee Doe in Estrus Model FDE1 Mrs. Doe Pee's Doe in Estrus is made from Estrus urine collected at the peak of the rut, blended with Fresh Doe Urine for an extremely effective buck enticer. Use pre-rut before the does come into heat. Use during full rut when bucks are most active. Use during post-rut when bucks are still actively looking for does. 1 oz.

IN CONFIDENCE

Perceptions of unconventional slow virus diseases of animals in the USA

Spraker suggested an interesting explanation for the occurrence of CWD. The deer pens at the Foot Hills Campus were built some 30-40 years ago by a Dr. Bob Davis. At or about that time, allegedly, some scrapie work was conducted at this site. When deer were introduced to the pens they occupied ground that had previously been occupied by sheep. Whether they were scrapie infected sheep or not is unclear.

CJD9/10022

October 1994

Mr R.N. Elmhirst Chairman British Deer Farmers Association Holly Lodge Spencers Lane BerksWell Coventry CV7 7BZ

Dear Mr Elmhirst,

CREUTZFELDT-JAKOB DISEASE (CJD) SURVEILLANCE UNIT REPORT

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.
