#肺炎支原体：有可靠的检测方法吗？

前天微博上有网友提问，给出了下面的化验单，我再一次震惊了：

震惊的原因是这化验单明显违背医学常识：大家都知道支原体是最小的原核细胞型微生物，大约0.1~0.2微米宽，1~2微米长，这么小的尺寸意味着光学显微镜根本看不到，或者即使勉强看到，也至多是一个小点，根本无法分辨具体是什么；肺炎支原体的细胞也不是圆圆的，而是细长的。

Mycoplasmas, are among the smallest self-replicating organisms, are parasitic species that lack a cell wall and periplasmic space, have reduced genomes, and limited metabolic activity. Mycoplasma pneumoniae cells have an elongated shape that is approximately 0.1–0.2µm (100-200 nm) in width and 1-2µm (1000-2000nm) in length. The extremely small cell size means they are incapable of being examined by light microscopy. 资料来源：https://en.wikipedia.org/wiki/Mycoplasma_pneumoniae
