我们采用同宿主重复感染的方法观察了体温对红内期间日疟原虫裂殖周期及其配子体感染力的影响。 材料与方法 先后选择豫南2例间日疟病人作为供血者,以离体吸血法感染经驯化的中华按蚊,置温度26±1℃和相对湿度70～80％的实验室饲养。子孢子进腺后,用单只蚊在志愿者手臂上叮咬,吸血后解剖,发现唾液腺内有子孢子者,为感染成功。2例感染者均为重复感染。即第一次以2只阳性蚊叮咬,隔 We used the same host repeated infection method to observe the body temperature during the red-phase of Plasmodium vivax clematis cycle and its gametophyte infectivity. Materials and Methods Two malaria patients were selected as blood donors in southern Henan and infected with domesticated Anopheles sinensis by in vitro vasculography. The animals were housed in a laboratory with the temperature of 26 ± 1 ℃ and relative humidity of 70 ~ 80%. Sporozoites into the gland, with a single mosquito bite in the volunteers arm, vampire dissection and found sporozoites within the salivary gland for infection. Two cases of infection were repeated infections. The first time to 2 positive mosquito bites, every other
