Blood parameters in BALB/c mice infected with MARV/Ang or MARV/Ang-MA. Whole blood and sera were collected at the indicated time points from individual BALB/c mice (3 to 9 per time point) infected with 2,000× LD50 MARV/Ang-MA or the equivalent MARV/Ang dose. The whole blood was analyzed with differential, and the following parameters are shown: white blood cell count (WBC) (A), lymphocyte count (LYM) (B), lymphocyte percentage (LY%) (C), monocyte percentage (MO%) (D), neutrophil percentage (NE%) (E), and platelet count (PLT) (F). Sera were analyzed for biochemistry, and the following values are shown: alkaline phosphatase (ALP) (G), alanine aminotransferase (ALT) (H), amylase (AMY) (I), total bilirubin (TBIL) (J), blood urea nitrogen (BUN) (K), and glucose (GLU) (L). The data are expressed as means ± standard errors. *, P < 0.05; ** P < 0.01; ***, P < 0.001 (significance was determined by comparing data for MARV/Ang and MARV/Ang-MA at the same time points).
