DNA reads obtained after NGS sequencing of LRTI samples.

aValid DNA reads after discarding those that did not pass the quality filter, and removing repeated reads (see Methods).DNA reads obtained after NGS sequencing of LRTI samples.经丢弃未通过质量过滤的DNA测序读段并去除重复读段后得到的有效DNA测序读段（详见方法部分）。从下呼吸道感染（Lower Respiratory Tract Infection，LRTI）样本经下一代测序（Next-Generation Sequencing，NGS）测序后获得的DNA测序读段。
