透过显微镜看八种病原体:爆发中的新流感(8)
8.线虫杀手

线虫杀手
Nematocida parisii是一种被称作微孢子虫(microsporidia)的原生寄生虫新品种,它生活在一种经常被用来做实验的小蛔虫——线虫(C.elegans)的肠内。在自来水里可发现微孢子虫,它能造成一系列感染,即微孢子虫病(microsporidiosis),这种疾病通过减弱免疫系统,对人体产生不利影响。
该寄生虫可引起肺、肾、大脑、肌肉、眼睛、窦房结或肠道感染,造成胆囊疾病,并削弱胃肠功能,其中包括慢性腹泻和消瘦。这张图片显示的是被染色的蛔虫的部分肠道,其中红色的是N. parisii的细胞质,蓝色的是它的DNA。
