Activity of Sanguisorba officinalis extract (SOE) against simian immunodeficiency virus (SIV), influenza, and severe acute respiratory syndrome coronavirus (SARS-CoV). Serially diluted SOE was added to (A) GHOST-CCR5 infected with SIVmac239, and SIVmac1A11, (B) 293T-ACE2 infected with SARS-CoV, and (C) MDCK cells infected with H5N1Anhui. (B,C) HIVHxB2 was tested as a positive control in GHOST-CXCR4 cells. The luciferase level was measured 2 days postinfection. All results are means ± standard errors of the means from three independent experiments.
