Abstract: The prion protein is the pathogenesis agent for transmissible spongiform encephlopathies (TSE) of human being and some mammal. The polymorphisms of the prion protein (PRNP)gene were significantly affect the susceptibility or resistance to TSE for human being and mammal. In this paper, we analyzed the origins, the monitoring and prevention of BSE. The structure and function of PRNP gene in cattle were introduced briefly.The polymorphism of bovine PRNP gene locating in non-coding region was analyzed systematically. We also summarized and compared the insertion-deletion (indel) in the promoter (23 bp) and the first intron (12 bp) polymorphism together for BSE susceptibility. These could assist the cattle molecular breeding project.

Key words: bovine spongiform encephalopathies (BSE); prion protein gene (PRNP); polymorphisms; resisitance
