Abstract Background Incubation period, disease progression, pathology and clinical presentation of classical scrapie in sheep are highly dependent on PRNP genotype, time and route of inoculation and prion strain. Our experimental model with pre-colos

a b s t r a c t The relationship between caprine PrP gene polymorphisms and susceptibility or resistance to scrapie has been actively investigated in recent years. The ORF of the PrP gene is highly variable in different breeds of goats. We studied th

The aim of this study was, under experimental conditions, to investigate infection of Nor-wegian White sheep with ovine and bovine isolates of Dichelobacter nodosus of varyingvirulence. In addition, the efficacy of gamithromycin as a treatment for th

This paper reviews some key aspects of important flock health issues in Scandinavia/northern Europe. The number of sheep in Scandinavia/northern Europe and the sheep livestock trend are shortly summarized, and focus is made on sheep disease diagnosti

The status of scrapie in Africa is largely unknown. The susceptibility to scrapie and its pathology is determined by amino acid polymorphisms at positions 136 (A/V), 154 (R/H) and 171 (Q/R/H) of the ovine PrP gene (PrP genotype) of the animals. Despi

Susceptibility to scrapie in sheep is largely influenced by four polymorphic amino acid positions of the ovine PrP gene at codons 136, 141, 154 and 171. Genotyping of corresponding DNA polymorphism can be used as a basis for selection decisions. A to

Scrapie has persisted in sheep for centuries, and most sheep-producing countries worldwide, with few exceptions, are, or may be, affected by the disease. Why is it that the Scrapie status in many countries is not known with certainty, why has the dis

Background Dichelobacter nodosus is the main causative agent of ovine footrot, and there are strong indications that the bacterium can be transferred to cattle grazing on the same pasture as sheep. The aim of this study was to investigate if benign a

Summary Scrapie diagnosis is based on the demonstration of disease-associated prion protein (PrP Sc ) in brain or, in the live animal, in readily accessible peripheral lymphoid tissue. Lymphatic tissues present at the rectoanal line were readily obta
