[Specific features of the parasitic system of Crimean haemorrhagic fever in Stavropol' region during epidemic season of 2000].

Information on Crimean haemorrhagic fever (CHF) in different climatic zones of the Krasnodar territory is presented. The epidemiological importance of some species of Ixodes ticks as vectors of the causative agent of CHF was shown. Ticks Hyalomma marginatum proved to be the main vector species: they constituted 75-100% of all ticks collected from cattle, reaching the peak of their abundance in May. This species was found to be more aggressive than Dermacentor marginatus.
