THE DYNAMICS OF ORTHOHANTAVIRUS HANTAAN STRAINS REPLICATION ON THE MODEL OF MOUSE PERITONEAL MACROPHAGES

Orthohantaviruses (Orthohantavirus genus, Hantaviridae family) are the causative agents of a widespread natural focal infection in the Russian Federation, hemorrhagic fever with renal syndrome (HFRS). An important role in the persistence of orthohantavirus in reservoir hosts among other immunolog...

An important role in the persistence of orthohantavirus in reservoir hosts among other immunological responses, as well as in the spread of the virus in the infected organism, is played by infected macrophages, which, along with the vascular endothelium, are the main targets for orthohantaviruses.The aim of our study was to investigate the characteristics of replication of orthohantavirus Hantaan strains isolated from Apodemus mice and detect the influence of different values of multiplicity of infection (MOI) on replication dynamics of orthohantaviruses on cell culture.Materials and methods. We used 4 strains of Hantaan virus, isolated from A. agrarius (n = 2) and A. peninsulae (n = 2), captured in the different areas of Primorsky Krai of Russia. The modeling of infection was performed on the primary cell culture of mouse peritoneal macrophages with different MOI (from 10 to 0.1). The assessing of infection was conducted via indirect fluorescent antibody assay, and results were expressed as rate of antigen- positive cells per all cells in the field of vision. Results.
