Serum chemistries and complete blood counts (CBCs) of rhesus macaques following SUDV exposure. Rhesus macaques were exposed intramuscularly to 1,750 plaque forming units of SUDV. Groups (n = 4) were treated I.V. with either 50 mg/kg of SUDV-specific mAb mixture 16F6/X10H2 and/or equal volume-to-weight ratio of vehicle (0.9% NaCl) on days 4 and 6 postexposure (Ctrl 3 and Ctrl 4 treated on day 5 only). (A–D) Serum and whole blood was collected on indicated days postexposure to evaluate serum enzymes (A) ALT, (B) AST, and (C) ALP by Piccolo and (D) platelet counts by CBC. Individual data points are from a single assay using instruments validated daily with appropriate instrument controls. Lines represent group means. *P < 0.05, **P < 0.01, ****P < 0.0001.
