We isolated a novel strain of tickborne encephalitis virus (TBEV), Glubinnoe/2004, from a patient with a fatal case in Russia. We sequenced the strain, whose landmark features included 57 amino acid substitutions and 5 modified cleavage sites. Phylogenetically, Glubinnoe/2004 is a novel variant that belongs to the Eastern type of TBEV.
The role of birds in the focus of tick-borne infections was studied from 2006 to 2011. The frequency index of ticks carried by ground dwelling birds is about 49.7%. The index of their abundance is 3.8. The larvae of ticks have been found on birds in 43.8% of cases. Nymphs and adult ticks have been found in 39.9 and 16.3%, respectively. It was revealed that… (More)
Five-hundred-and-six Hyalomma anatolicum ticks were collected and studied in two Crimean-Congo hemorrhagic fever (CCHF) endemic regions of Tajikistan. Antigen and RNA of the CCHF virus were detected in 3.4% of tick pools from the Rudaki district using ELISA and RT-PCR tests. As for the Tursunzade district, viral antigen was identified in 9.0% of the samples… (More)
We caught, 2002-2003 in caves of Novosibirsk Region and Altai Territory, 52 bats (Myotis daubentoni, Myotis brandtii, Murina leucogaster, Plecotus auritus). Examinations of the animals' brain samples by fluorescence antibody microscopy and RT-PCR revealed lyssaviruses, genotype 1, which were close to strains provoking rabies in the local animals.
