The samples were chosen on the basis of regional variation in benzimidazole treatment background of sheep flocks. Our objective was to study the relationship between treatment background andβ -tubulin gene polymorphism of H. contortus isolated from the selected regions. H. contortus isolated from Shooshtar revealed reduction in β-tubulin gene polymorphism restriction fragment length polymorphism (RFLP) in respect to other isolates indicating that benzimidazole-resistant isolates of H. contortus  developed in some sheep flock of Shooshtar region.     UR - https://ijvr.shirazu.ac.ir/article_1755.html L1 - https://ijvr.shirazu.ac.ir/article_1755_c94fe7bbcd0107a4e7b6e639c1b953bd.pdf ER -
