Abstract:
Screening for polymorphism at the prion protein (PrP) locus (PRNP) was carried out in 33 flocks of Local Awassi (LA) sheep in Israel, the Palestinian Authority (PA) and Jordan. In addition, PRNP genotyping was carried out in two flocks of Improved Awassi (IA) in Israel and the PA and in 11 flocks of Assaf sheep in Israel. Most of the rams present in the flocks at the time of the survey 328, 44 and 298 rams from the LA, IA and Assaf breeds, respectively, were genotyped. The ARQ allele was found to be predominant in all three breeds with average frequencies of 0.74, 0.78 and 0.86 for the LA, IA and Assaf breeds, respectively. Frequencies of the desirable ARR allele in these breeds were 0.10, 0.05 and 0.06, respectively. ARH, AHQ and ARK alleles were identified at low/absent frequencies. Only one Assaf ewe carried the undesirable V allele at codon 136. A few scrapie outbreaks have been documented in the past in the region. To increase ARR allele frequencies in the Awassi and Assaf populations, distribution of homozygous ARR/ARR rams is recommended. © 2008 Elsevier B.V. All rights reserved.
