The level of resistance to infection with Plasmodium chabaudi is genetically controlled. We have previously reported that a single dominant gene is responsible for the variation in host resistance to malaria between susceptible A/J- and resistant C57BL-derived mice. In the present study, recombinant inbred strain analysis was performed with AXB/BXA recombinant inbred strains derived from A/J and C57BL/6 progenitors. Typing of 17 AXB/BXA recombinant inbred strains confirmed the unigenic control of inheritance in this particular strain combination and allowed us to demonstrate genetic linkage between the traits of resistance (defined as a prolonged survival and a low peak parasitemia) and the magnitude of splenomegaly. The influence of sex on the course of infection, which we previously reported in the examination of segregating populations (Stevenson et al., Infect. Immun. 38:80-88, 1982), was again demonstrated in the survey of RI strains.
对查巴迪疟原虫感染的抵抗力水平受基因控制。我们之前报道过,一个单一的显性基因负责易感的A/J小鼠和抗性的C57BL衍生小鼠之间宿主对疟疾抵抗力的差异。在本研究中,对源自A/J和C57BL/6祖代的AXB/BXA重组近交系进行了重组近交系分析。对17个AXB/BXA重组近交系的分型证实了在这种特定品系组合中遗传的单基因控制,并使我们能够证明抗性性状(定义为延长存活时间和低峰值寄生虫血症)与脾肿大程度之间的遗传连锁。我们之前在对分离群体的研究中报道过的性别对感染过程的影响(Stevenson等人,《感染与免疫》38:80 - 88,1982),在对重组近交系的调查中再次得到证实。
