Pneumocystis organisms were first identified by Carlos Chagas in the early 20th century, with the use of a guinea-pig model of trypanosome infection, and subsequently by Antonio Carinii, in infected rat lungs.4,5 Both investigators believed they had identified new forms of trypanosomes.

卡氏肺孢子生物首次发现由卡洛斯恰加斯在20世纪初，随着使用一种豚鼠模型锥虫感染，并随后由安东尼奥马刺虫，在受感染的大鼠lungs.4 ，五两，调查人员认为他们已确定的新形式锥虫。

Serious attention to the trypanosomes of mammals was drawn by the work of Timothy Lewis on the parasite of Indian rats, the importance of which was realized after Griffith Evans (1880) discovered the pathogenic trypanosome in horses and camels in India Trypanosoma evansi

Timothy Lewis对印度老鼠的寄生虫的研究引起了人们对于哺乳动物锥虫病的严重关注。Griffith Evans (1880)在印度发现马和骆驼身上的致病性锥虫之后，人们才认识到了哺乳动物锥虫病的重要性。

Experimental mice were exposed to Trypanosome evansi after injection by different doses of antigenic reservoir. The results showed that 20 μg dose produced 83% and 67% protection to 2 sample variations after 4 immunizations. However, 3 immunizing doses could not give good protection. No protective effects were detected when experimental animals immunized by single VSG exposed to isotype from different rabbits.

用不同剂量抗原库免疫小鼠后进行攻虫，结果显示：经四次免疫后，20μg 剂量对随机抽取的两个变异体100 条虫体的保护率分别达到 83%和 67%；改变免疫方法，经三次免疫后的保护效果不理想；用单一 VSG 抗原免疫小鼠，接种来自不同兔体的同型虫体，不能起到相应保护作用。

目的分析锥虫亚属布氏锥虫、伊氏锥虫和马媾疫锥虫3个种以及布氏锥虫：指名亚种、冈比亚亚种、罗得西亚3个亚种间的遗传变异与进化关系。

The CCND2 expression cell proliferation, cell cycle and cell apopotosis of the transfected LP-1 cells were studied by RT-PCR, trypanosome staining, flow cytometry and annexin V assay.

设计、合成CCND2短发夹RNA双链DNA模板，构建表达质粒pGenesil-2／CCND2，转染LP-1细胞，以RT—PCR检测对CCND2表达的抑制作用，以锥虫蓝染色计数和MTI检测细胞增殖，以Annexin V检测细胞凋亡，流式细胞术检测细胞周期。

Immune response research shows one of the antimicrobial peptide, Attacin, was upregulated expressed in the tsetse fat body after trypanosome infection. But the infection was not effectively cleared due to the late response or expression site discrepancy .

对采采蝇的免疫研究发现它在感染锥虫后会诱导表达一种抗菌蛋白，Attacin，但由于时间太晚以及表达部位的原因，并不能有效地清除体内的锥虫感染，而当人为地诱导表达Attacin后再感染锥虫则可以发现感染率显著下降。

VAT ShTat1.1,ShTat1.2,ShTat1.3 and ShTat1.5were taken to study their growth characteristic,sensitivity to human serumand pathogenicity to mice.The result showed biological characteristic ofdifferent VAT were not all the same,which implied that antigenic variationof T.evansi was accompanied with variation of trypanosome otherphysiology and biochemistry property.
