We established a new field clone of Plasmodium falciparum for use in controlled human malaria infections and vaccine studies to complement the current small portfolio of P. falciparum strains, primarily based on NF54. The Cambodian clone NF135.C10 consistently produced gametocytes and generated substantial numbers of sporozoites in Anopheles mosquitoes and diverged from NF54 parasites by genetic markers. In a controlled human malaria infection trial, 3 of 5 volunteers challenged by mosquitoes infected with NF135.C10 and 4 of 5 challenged with NF54 developed parasitemia as detected with microscopy. The 2 strains induced similar clinical signs and symptoms as well as cellular immunological responses.

我们建立了一个新的恶性疟原虫野外分离株,用于控制人体疟疾感染和疫苗研究,以补充目前主要基于 NF54 的少数恶性疟原虫株。柬埔寨分离株 NF135.C10 始终产生配子体,并在按蚊中产生大量的子孢子,且与 NF54 寄生虫通过遗传标记而分化。在一项控制人体疟疾感染试验中,经 NF135.C10 感染的蚊子感染的 5 名志愿者中的 3 名和经 NF54 感染的 5 名志愿者中的 4 名出现了显微镜可检测的寄生虫血症。这 2 个株系诱导了相似的临床体征和症状以及细胞免疫反应。
