FIG. 2.
Kinetic analysis of circulating lymphocytes following influenza virus infection. BALB/c mice (3 or 4 mice/group) were inoculated i.n. with 105 EID50 or PFU of each virus shown. Blood was collected on day 3 (A) or 6 (B) p.i. in EDTA Vacutainer tubes and analyzed with a hematology scanner. Blood collected immediately prior to inoculation was included as a baseline control (naïve). The average percentages of lymphocytes (LY), neutrophils (NE), monocytes (MO), eosinophils (EO), and basophils (BA) in whole blood are shown.
