Development, production and characterization of SARS-CoV-2 virus-like particles (Coronaviridae: ).

Introduction: The COVID-19 pandemic caused by SARS-CoV-2 has created serious health problems worldwide. The most effective way to prevent the occurrence of new epidemic outbreaks is vaccination. One of the modern and effective approaches to vaccine development is the use of virus-like particles (VLPs).

Prevalence and Genetic Diversity of Group A Rotavirus Genotypes in Moscow (2019-2020).

Group A rotavirus (RVA) infection is the leading cause of hospitalization of children under 5 years old, presenting with symptoms of acute gastroenteritis. The aim of our study was to explore the genetic diversity of RVA among patients admitted to Moscow Infectious Disease Clinical Hospital No. 1 with symptoms of acute gastroenteritis.

[Synthesis and characterization of human rotavirus A () virus-like particles].

Introduction: Rotavirus infection is the leading cause of acute gastroenteritis among infants. The development of new vaccines against rotavirus A is urgent because the virus has many genotypes, some of which have regional prevalence. Virus-like particles (VLP) is a promising way to create effective and safe vaccine preparations.

Genetic diversity of group A rotaviruses in Moscow in 2018-2019.

Here, we present the results of a study in which 639 samples obtained between October 2018 and April 2019 from patients with symptoms of acute gastroenteritis were tested for the presence of a rotavirus infection. The antigen of group A rotavirus was detected in 160 samples (25% of those tested). To study the genetic diversity of group A rotavirus, RNA was isolated from the samples, and polymerase chain reaction combined with reverse transcription (RT-PCR) with primers specific for the VP4, VP6, and VP7 genes of group A rotaviruses was performed.
