Molecular techniques for the control of diseases in sheep. An application to control scrapie in sheep

Ioannides I.M., Papachristoforou C., Koumas A., Mavrogenis A.P.

The program aims to establish a nucleus unit with animals of the RR genotype from which to draw genetic material in terms of live animals and semen. Four hundred DNA samples from Chios sheep were screened for polymorphisms in the PrP gene using DGGE. A total of 101 RR and 202 RQ genotypes were detected and were used in private flocks and in the nucleus, breeding unit. The remaining ninety-seven individuals tested were found susceptible to scrapie and consequently they were slaughtered. The sex distribution of genotypes of the nucleus unit is 58 RR and 144 RQ females and 42 RR males.
