Leucocytozoon caulleryi, the most important pathogen of leucocytozoonsis in several Asian countries, is transmitted by Culicoides arakawae. Although the vector blood meal factors that influence the infectivity of L. caulleryi remain poorly understood, the factors in infected chicken serum remain vital. C. arakawae blood-fed through a membrane were used in this experiment to examine the influence of serum factors on L. caulleryi development. Experimental results indicate that C. arakawae were successfully blood-fed through a chicken-egg-shell membrane and the serum factors in infected chicks significantly affected L. caulleryi sporogony. The inhibition effect of serum factors calculated from sporozoite averages was 53.6% +/- 2.2%. The serum factors, including transmission-blocking antibody, require further detailed study.
卡氏住白细胞虫是亚洲多个国家白细胞虫病最重要的病原体，由新田库蠓传播。尽管影响卡氏住白细胞虫感染力的媒介血餐因素仍知之甚少，但感染鸡血清中的因素仍然至关重要。本实验使用通过膜进行血餐的新田库蠓来研究血清因素对卡氏住白细胞虫发育的影响。实验结果表明，新田库蠓通过鸡蛋壳膜成功进行了血餐，感染雏鸡的血清因素显著影响卡氏住白细胞虫的孢子生殖。根据子孢子平均数计算的血清因素抑制率为53.6%±2.2%。包括传播阻断抗体在内的血清因素需要进一步详细研究。
