Tick-borne encephalitis virus (TBEV) is transmitted to vertebrates by taiga or forest ticks through bites, inducing disease of variable severity. The reasons underlying these differences in the severity are unknown. In order identify genetic factors affecting pathogenicity strains, we have sequenced and compared complete genomes 34 Far-Eastern subtype (FE) TBEV strains isolated from patients with different (Primorye, Russian Far East). We analyzed 11 human pathogenic brains dead encephalitic...
The disease of freshwater sponges was first discovered in 2011, when pink samples were found the Central Basin Lake Baikal. Subsequently, visible signs have changed, and now appear with various symptoms damage to body, such as discoloration, tissue necrosis, formation brown patches dirty-purple biofilms on some branches. These are accompanied by mass death sponges. We identified differences microbiomes sequencing 16S rRNA genes changes consortium microorganisms Baikal that observed imbalance...
A holdfast is a root- or basal plate-like structure of principal importance that anchors aquatic sessile organisms, including sponges, to hard substrates. There date little information about the nature and origin sponges' holdfasts in both marine freshwater environments. This work, our knowledge, demonstrates for first time chitin an important structural component within endemic demosponge Lubomirskia baicalensis. Using variety techniques (near-edge X-ray absorption fine structure, Raman,...
The phylogenetic relationship of the freshwater sponges (Porifera) in Lake Baikal is not well understood. A polyphyletic and/or monophyletic origin have been proposed. (endemic) Baikalian subdivided into two families: endemic Lubomirskiidae and cosmopolitan Spongillidae. In present study, new approaches made to resolve sponges; analysis (1) nucleotide sequences from one mitochondrial gene, cytochrome oxidase subunit I (COI) (2) selected intron tubulin gene. Specimens following sponge species...
The virus epizootic which resulted in significant mortality Siberian seals ( Phoca sibirica ) Lake Baikal during 1987/88 was caused by canine distemper virus. Sequence analysis of the glycoprotein genes revealed that it most closely related to recent European field isolates This paper presents evidence same continued circulate after initial epizootic. Three out 45 brain tissue samples collected from culled spring 1992 were positive for virus‐specific nucleic acid reverse...
The endemic freshwater sponge Lubomirskia baicalensis lives in Lake Baikal winter (samples from March have been studied) under complete ice cover at near 0 degrees C, and summer open water 17 C (September). In March, specimens show high metabolic activity as reflected by the production of gametes. L. symbiosis with green dinoflagellates, which are related to Gymnodinium sanguineum. Here we that these dinoflagellates produce toxin okadaic acid (OA), is present a free molecule well...
Among the tailed phages, myoviruses, those with contractile tails, are widespread and diverse. An important component of Myoviridae family is genus 'T4-like viruses'. The present study was aimed at elucidating molecular diversity T4-type bacteriophages in Lake Baikal by partial sequencing g23 genes bacteriophages. Our revealed that gene sequences investigated were highly diverse different from T4-like clones obtained environments. Phylogenetic analysis showed all fragments Baikal, except for...
Lake Baikal is a unique oligotrophic freshwater lake with unusually cold conditions and amazing biological diversity. Studies of the lake’s viral communities have begun recently, their full diversity not elucidated yet. Here, we performed DNA metagenomic analysis on integral samples from four different deep-water shallow stations southern central basins lake. There was strict distinction in areas environmental conditions. Comparative other lakes revealed highest similarity viromes those...
