本文作者观察了恶性疟原虫自然获得性免疫在儿童与成人免疫系统中的不同作用。人体对恶性疟原虫的免疫力包括二部分:抗毒素免疫和抗原虫免疫。抗毒素免疫的中介期(虽然感染者原虫血症水平很高,但仅有轻微或无临床症状)见于生活在高疟区的人群。在原虫血症的水平已降低(尽管仍持续接触感染),而真正的抗原虫免疫产生前,这种获得性防御机制在接触感染被阻断后就完全丧失保护作用,人体对新的暴露又相当易感。
The authors looked at the different roles of P. falciparum naturally acquired immunity in the immune system of children and adults. Human immunity to Plasmodium falciparum includes two parts: antitoxin immunity and anti-protozoal immunity. The intermediate phase of antitoxin immunity (although high levels of protozoosin but only mild or no clinical signs) is found in people living in areas of high malaria. In the event that the level of protozoa has been reduced (although exposure continues to occur), this acquired defense mechanism completely loses its protective effect after the contact infection is blocked before the actual anti-protozoal immunity is established. The new exposure of the human body to Very easy to feel.
