[EPIDEMIOLOGIC SITUATION BY NATURAL-FOCI INFECTIONS IN THE CRIMEA FEDERAL DISTRICT IN 2014-2015].

Aim: Analysis of epidemic manifestations of natural-foci infections (NFI), clarification of spectrum of their causative agents, determination of epizootic activity of natural foci in the Crimea Federal District (KFD).

Materials And Methods: Epizootologic examination of 10 administrative districts of KDF was carried out. 291 pools (2705 specimens) of ixodes ticks and 283 samples of organs of small mammals were studied by PCRmethod for the presence of DNA/RNA of causative agents of a number of NFI.
