Development and Validation of a Protein Array for Detection of Antibodies against the Tick-Borne Pathogen Borrelia miyamotoi.

Current serological tests for the emerging tick-borne pathogen Borrelia miyamotoi lack diagnostic accuracy. To improve serodiagnosis, we investigated a protein array simultaneously screening for IgM and IgG reactivity against multiple recombinant B. miyamotoi antigens.

[The information content and predictive value of cardiac markers in myocardial infarction in the elderly.].

Myocardial infarction in old age is the leading pathology and cause of deaths. The aim of the study was to evaluate the prognostic significance and informative value of cardiac markers of blood in elderly patients with myocardial infarction. The study of cardiac markers in 107 patients with myocardial infarction at the age of 65-75 years and in 83 patients with myocardial infarction at the age of 50-60 years was carried out by immunochromatographic, bioluminescent methods and by electrophoresis on cellulose acetate, followed by the calculation of informativeness and prognostic coefficients.

Whole genome sequencing of Borrelia miyamotoi isolate Izh-4: reference for a complex bacterial genome.

Background: The genus Borrelia comprises spirochaetal bacteria maintained in natural transmission cycles by tick vectors and vertebrate reservoir hosts. The main groups are represented by a species complex including the causative agents of Lyme borreliosis and relapsing fever group Borrelia. Borrelia miyamotoi belongs to the relapsing fever group of spirochetes and forms distinct populations in North America, Asia, and Europe.

Evaluation of the population heterogeneity of TBEV laboratory variants using high-throughput sequencing.

We studied minor variants within two tick-borne encephalitis virus (TBEV) populations with a common ancestor: the mouse brain-adapted variant EK-328c and the tick-adapted variant M. High-throughput sequencing with custom amplicons from RT-PCR viral RNA was performed on Illumina MiSeq 2*250 paired-end v2 chemistry. Using the LowFreq program (default settings) and Sanger-sequenced consensus as a reference, variants with an abundance of 1 % and above within the studied populations were identified.

Whole-Genome Sequencing of Six Clinical Strains Isolated in Russia.

Here, we report the whole-genome sequence of six clinical isolates from the Russian Federation. Using two independent next-generation sequencing platforms, we determined the complete sequence of the chromosome and several plasmids. All strains have an Asian genotype with 99.
