Figure 3. A) Virus isolation confirmed by reverse transcription PCRSosV was isolated after intracranial and intraperitoneal inoculation into 2-day-old suckling miceA specific reverse transcription PCR designed to amplify 2,188 bp of the SosV genome was performed by using RNA from brains (Br), liver (Lv), and spleen (Sp) of the euthanized animalsViral RNA was found only in the brain, not in liver or spleenB) Propagation of SosV in cell cultureHomogenized tissues (brain, liver, and spleen) were used to infect H292 cellsFixed monolayers were stained with convalescent-phase serum from the patient and anti-human AlexaFluor 488 antibody (Invitrogen, Grand Island, NY, USA)C) Sosuga virus particleVirus morphologic appearance was examined by taking supernatants from infected Vero-E6 cells, clarifying by slow-speed centrifugation, and depositing on grids for negative staining and examination by transmission electron microscopyPleomorphic virions can be observedNeg.ctrl, negative control; Se, serum; SosV, Sosuga virus.
