Flow cytometry was used to quantify the percentage of apoptotic hepatic Caracimoma cells infected with bluetongue virus HbC3 and stained with propidium iodide (PI) and Annexin V/PI. The percentages of the apoptotic cells measured by PI at 24h, 36h and 48h were 10.8 ±3.05, 21.7±6.28, 28.3±10.6, respectively, and those by Annexin V-PI were 20.42±3.70, 49.3±8.11, 79.6±11.5, respectively. The two staining methods and the rate of apoptotic cells infected by bluetengue virus hours were significantly different (P<0.01). The early apoptotic cells and secondary necrosis could be detected by AnnexinV/PI assay with good sensitivity and specificity. The apoptotic cells induced by bluetengue virus was one of the important forms in the pathological changes and cell necrosis.
