SCRAPIE PROGRAM FY REPORT 2007
Prepared by National Center for Animal Health Programs Ruminant Health Programs Team November 15, 2007
Infected and Source Flocks
During FY 2007, there were a total of 76 new infected or source flocks identified. Of those new flocks identified, 30 were infected flocks and 46 were source flocks (Figure 2). As of September 30, 2007, there were 38 scrapie infected and source flocks with open statuses (Figure 3). ...
In FY 2007, 331 scrapie cases have been confirmed and reported by the National Veterinary Services Laboratories (NVSL), including 59* Regulatory Scrapie Slaughter Surveillance (RSSS) cases (Figure 5 and Slide 16). In FY 2007, two field cases, one validation case, and two RSSS cases were consistent with Nor-98 scrapie. The Nor98-like cases originated from flocks in California, Minnesota, Colorado, Wyoming and Indiana respectively. Nineteen cases of scrapie in goats have been reported since 1990 (Figure 6). The last goat case was reported in September 2007.

Aspects of the Cerebellar Neuropathology in Nor98
Gavier-Widén, D1; Benestad, SL2; Ottander, L1; Westergren, E11National Veterinary Insitute, Sweden; 2National Veterinary Institute, Norway
Nor98 is a prion disease of old sheep and goats. This atypical form of scrapie was firstdescribed in Norway in 1998. Several features of Nor98 were shown to be differentfrom classical scrapie including the distribution of disease associated prion protein(PrPd) accumulation in the brain. The cerebellum is generally the most affected brainarea in Nor98. The study here presented aimed at adding information on theneuropathology in the cerebellum of Nor98 naturally affected sheep of variousgenotypes in Sweden and Norway. A panel of histochemical and immunohistochemical(IHC) stainings such as IHC for PrPd, synaptophysin, glial fibrillary acidic protein,amyloid, and cell markers for phagocytic cells were conducted. The type of histologicallesions and tissue reactions were evaluated. The types of PrPd deposition werecharacterized. The cerebellar cortex was regularly affected, even though there was avariation in the severity of the lesions from case to case. Neuropil vacuolation wasmore marked in the molecular layer, but affected also the granular cell layer. There wasa loss of granule cells. Punctate deposition of PrPd was characteristic. It wasmorphologically and in distribution identical with that of synaptophysin, suggestingthat PrPd accumulates in the synaptic structures. PrPd was also observed in thegranule cell layer and in the white matter. The pathology features of Nor98 in thecerebellum of the affected sheep showed similarities with those of sporadicCreutzfeldt-Jakob disease in humans.

i am reminded of a few things deep throat (high ranking official at usda)told me years ago;
The most frightening thing I have read all day is the report of Gambetti's finding of a new strain of sporadic cjd in young people.........Dear God,
