Frequency of positive pox-antigen immune cells in the blood.

*granulocytes and monocytes cannot be clearly distinguished by FSC/SSC gating in some samples when virus infection is severe. Thus the two populations were gated together as one population for analysis. Value is the subtraction of isotype control staining from the pox-antigen staining result. The data does not include result from survivors, which all gave a value <0.2%.
**for the NHPs that reached moribund after day 8, day 8 analysis was included in the table. Otherwise, the data from necropsies between day 5 and day 8 was included.

*当病毒感染严重时，部分样本无法通过前向散射光/侧向散射光（FSC/SSC）设门清晰区分粒细胞（granulocytes）与单核细胞（monocytes）。因此将这两类细胞群合并设门作为单个群体进行分析。检测值为痘病毒抗原（pox-antigen）染色结果减去同型对照（isotype control）染色的结果。本数据集未纳入存活个体的检测结果，所有存活个体的检测值均低于0.2%。
**对于在第8天后进入濒死状态的非人类灵长类动物（Non-Human Primates, NHPs），表格中纳入其第8天的检测数据；其余实验动物则纳入其在第5日至第8日之间剖检（necropsy）获取的检测数据。
