摘要

Scrapie is an infectious neurodegenerative disease affecting the central nervous system of sheep and goats that belongs to transmissible spongiform encephalopathies. The disease is caused by the accumulation of proteinase-resistant isoform of the prion protein. The sheep predisposition to scrapie is associated with polymorphisms of the PrP gene. Genetic susceptibility to scrapie is mainly related to codons 136, 154, and 171. ARR sheep are strongly scrapie resistant and VRQ genotype is the most susceptible. Many countries have scrapie eradication programs based on using rams with resistant genotype. The eradication program has not yet been implemented in the Republic of Serbia. To examine the genetic makeup of sheep in Serbia related to scrapie, we optimized TaqMan probes of real-time polymerase chain reaction (qPCR) technique for three codons. Blood samples from 100 sheep were analyzed by qPCR and the majority of the examined sheep were AA homozygous for the 136 codon. For codon 154 the most frequent genotype was RR and for codon 171 the most frequent genotype was QQ.
