Differentiation of geographical populations of liver fluke <i>Fasciola hepatica </i>on the grounds of tubulin-β2 gene polymorphism (<i>tubb2</i>)
For the first time it is shown <i>Fasciola hepatica </i>tubulin-β2 gene structure, the product of which is probably the main target of the benzimidazoles. The suitability of the gene for differentiation of geographical populations of <i>F. hepatica </i>from Russia and Great Britain is shown. It is discussed the causes of mutations in coding regions of the gene and association of observed polymorphism with action of an-thelminthics.
