And then of course there's tubercular meningitis which is caused by the Mycobacterium tuberculosis bacteria, and finally parasitic causes of meningitis like P. falciparum which is the main cause of malaria.

然后当然还有结核性脑膜炎，由结核分枝杆菌引起；最后还有脑膜炎的寄生病因，比如像是恶性疟原虫，也是疟疾的主要病因。

Knocking out just three of the 5000 genes in the P. falciparum genome can prevent sporozoites from maturing and reproducing, so they can’t infect the bloodstream.

仅敲除恶性疟原虫基因组中 5000 个基因中的三个，就可以阻止子孢子成熟和繁殖，因此它们无法感染血液。

Even the best vaccine developed so far, which was engineered with part of a protein produced by the most dangerous parasite, P. falciparum, only works about a third of the time and requires regular booster doses.

即使是迄今为止开发的最好的疫苗，它是用最危险的寄生虫恶性疟原虫产生的部分蛋白质设计的， 也只有大约三分之一的时间有效， 并且需要定期加强剂量。
