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 Fasciola hepatica 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 F. hepatica 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.
