[Comparative estimation of the indicators of interferon, immune, and cytokine states in the comprehensive study of patients with herpesvirus infections].

The authors studied the pathology of bone marrow (BM) lymphoid cell from pigs infected by African swine fever virus (ASFV) in vitro. Monocytes were shown to be primarily afflicted in unstimulated BM culture. These cells disappeared completely 72 hours after infection. Just 24 hours following ASFV infection, there were atypical lymphocytes amounting to 12% of the general lymphoid population at hour 72 after inoculation.The area and perimeter of minor, middle, and large lymphocytes tended to reduce during both BM cell cultivation and inoculation. Lymphoblasts and monocytes were generally triploid in both the control and test groups, but among them there were diploid, triploid, and tetraploid cells. Cytophotometric assay revealed that the amount of nuclear DNA significantly increased in BM lymphoblasts and monocytes in the early stages of ASFV infection (within 24 hours). This effect was also rather pronounced in the lymphoblasts in the later stages (at hour 72).
