  1. Different superscripted lettersa,b,c within a row indicate significant differences (P ≤ 0.05) between the values. The results are shown as the mean ± SD.
  2. AL: aleukemic BLV-infected cows; PL: BLV-infected cows with persistent lymphocytosis; PI: propidium iodide; S. aureus: Staphylococcus aureus; ROS: reactive oxygen species; MFI: median fluorescence intensity.
