Bioaccumulation and retention of Po-210 and Pb-210 in two species of mosses from the zone of influence of the former radium-extracting plants.

The presented study was aimed at assessing the ability to accumulate and retain Po and Pb in two species of the mosses Sphagnum girgensohnii Russow and Pleurozium schreberi (Willd. ex Brid.) Mitt.

Molecular epidemiology of Crimean-Congo hemorrhagic fever virus in Russia.

In this report, we present new data on the diversity and geographical distribution of genetic variants in Crimean-Congo hemorrhagic fever virus (CCHFV) in Russia. Partial S, M, and L segment sequences of the CCHFV genome were obtained from 500 serum samples from CCHF patients and 103 pools of ticks collected in the south of the European region of Russia in 2007-2017. The investigated viral strains belonged to the lineages Europe 1 (596 samples), Africa 3 (1 sample) and a new genetic lineage, Europe 3 (6 samples).

Detection of Crimean-Congo hemorrhagic fever virus in ticks collected from South Russia.

Crimean-Congo hemorrhagic fever (CCHF) has a central role among tick-borne infections in southern Russia. Multiple cases of disease are recorded annually in most regions with the СCHF foci; moreover, an expansion of the geographic range of the disease has been noted. Since 1999, more than 2300 people have fallen ill in Russia.

[EPIZOOTOLOGIC MONITORING OF NATURAL-FOCAL INFECTIONS IN THE SOUTH OF RUSSIA IN 2015].

Aim: Analyze epizootologic manifestations of natural-focal infections (NFI) in the south of Russia in 2015.

Materials And Methods: Reports provided by administrations of Federal Service of Surveillance for Protection of Consumers Rights and Human Welfare, Centers of Hygiene and Epidemiology, Research Institutes for Plague Control and Station for Plague Control were used. Data processing was carried out using Excel program.

A NEW GENETIC VARIANT OF THE CRIMEAN-CONGO HEMORRHAGIC FEVER VIRUS ISOLATED IN CRIMEA.

This work represents the results of the genetic identification of the Crimean-Congo hemorrhagic fever virus (CCHF virus) strains isolated in the Crimean Federal District in conducting the epidemiological survey of the imported case of CCHF from Crimea in 2015. One sample of the serum from a patient and 61 pools (506 specimens) of ticks collected during the epizootiological survey of 6 administrative districts of the Crimean Federal District were tested using PCR for the presence of the CCHF virus RNA. RNA of the CCHF virus was detected in serum from a patient and 10 samples of ticks.
