Conteúdo: | Resistance to natural scrapie in sheep bas been associated with polymorphisms at codons 136, 154 and 171 of the prion protein (PrP). This study was undertaken to obtain preliminary information on the PrP gene-associated susceptibility to scrapie in the native sheep breed of the Spanish Basque Country (Latxa), where a single case of scrapie bas been reported. Six hundred and ninetyeight sheep from 10 commercial scrapie-free flocks were analysed. The genotype associated with a higher resistance (ARR/ARR) was present in 5.9%, whereas that associated with the highest susceptibility (homozygous VRQ) was absent. ical disease. ARQ/ARQ was the genotype most frequently observed (48.8%),indicating that susceptibile animals exist in the absence of clinicaldisease.This study provides base-line data for genotype frequencies of Latxa breed that can be included among the criteria used for breed selection to increase the frequencies of resistant genotypes without losing oout on productive characteristics.
