  1. Blood samples were taken following the observation of EEHV-1 infection clinical signs. WBC, lymphocyte, monocyte and platelet counts (highlighted in bold) consistently show substantial drop from their physiological level in the two fatalities caused by EEHV-1A. Percentages of monocytes in the white blood cells are also given in the table
  2. WBC, white blood cell count; RBC, red blood cell count; HGB, haemoglobin; MCV, mean cell volume; MCH, mean corpuscular haemoglobin; MCHV, mean corpuscular haemoglobin volume; RDW, red blood cell distribution width; PLT, platelet count; PCV, packed cell volume; NA, not available
