Unlabelled: Modern molecular genetic methods, massive parallel sequencing in particular, allow for genotyping of various pathogens with the aim of their epidemiological marking and improvement of molecular epidemiological surveillance of actual infections, including cytomegalovirus infection. is to evaluate the next-generation sequencing (NGS) technology for genotyping clinical isolates of cytomegalovirus (CMV).
Materials And Methods: The object of the study were samples of biological substrates (leukocyte mass, saliva, urine) taken from patients who underwent liver and kidney transplantation.
Unlabelled: was to develop an algorithm for the selection of discriminating probes to identify a wide range of causative agents of human infectious diseases.
Materials And Methods: The algorithm for selecting the probes was implemented in the form of the disprose (DIScrimination PRObe SElection) computer program written in the R language. Additionally, third-party software was used: the BLAST+ and ViennaRNA Package programs.
The characteristics of resistome and virulome structure of four carbapenem-resistant Klebsiella pneumoniae clinical strains are present in the work. Two strains belonged to the sequence-type ST395, one strain - ST2262, one strain - to the new sequence-type 5816. The genes of fimbriae, enterobactin, beta-lactamase SHV type, resistance to fosfomycin fosA and transport of fluoroquinolones oqxAB in all Klebsiella strains chromosome structure were identified.

The protein sequences of the studied strains were found to have a high degree of homology. (M45, M57, MH1866) was shown to have limited biosynthetic capabilities, associated with the predominance of the genes encoding the proteins involved in catabolic processes.

In the present study, we conducted a phylodynamic analysis based on the complete sequences of 11 segments of rotaviruses with the G4P[8] and G2P[4] genotypes isolated in Russia in 2017. Since rotavirus has a segmented genome, our analysis was performed using the Bayesian approach based on separate samples of nucleotide sequences for each gene of the strains studied.
