摘　　要：目的了解三峡库区人、哺乳动物、媒介生物间附红细胞体感染情况及分布。方法采集人群、哺乳动物、禽(鸟)类等血液涂片镜检、医学昆虫解剖压片镜检附红细胞体。结果健康人群附红细胞体感染率为56.11%,新生儿脐带血阳性率为96.59%。调查各种动物19种,阳性17种。其中家畜类阳性率为93.03%,家禽类为80.85%,啮齿类为56.29%;野生哺乳动物类为100%;青蛙、蛇类未发现阳性。鸟类阳性率为80.95%;昆虫类:蚊类阳性率为72.12%,蜱类为100%,虱类为89.36%,刺蝇类为91.78%,蚤类为42.86%,螨类为66.67%。结论从病原学上证实三峡库区为附红细胞体病重度流行区。可在哺乳动物及其他多种生物中寄生,猪及多种哺乳动物是重要储存宿主,昆虫是主要传播媒介,也可垂直传播。Objective To study the epidemic status of eperythrozoonsis in humen, mammalian, transmitting vectors in the area of Three Gorges Reservoir. Methods Capillary blood was collected, fixed up, dyed and then examined the eperythrozoon for infective rate of human, mammalian and bird using microscope. The insects and acarids were anatomized and examined for the eperythrozoon using microscope. Results The infective rate of human was 56.11%, the infective rate of new horns was 96.59%. 19 species animals was investigated and 17 species were infected by eperythrozcon. The infective rate of domestic animals was 93.03%, that of poultry 80.85%, of rodent 56.29%, of other mammalian animals 100%. There was no eperythroz0on found in frogs and snakes. The infective rate of mosquits, ticks, louse, stablefly, flea and acarid was respectively 72.12%, 100%, 89.36%, 91.78%, 42.86% and 66.67% respectively. Conclusion The area of Three Gorges Reservoir is epidemic region of eperythrozoonsis. Many animals infected by eperythrozcon and the infective rates are high in some animals. Insects may be transmission medium of eperythrozoonsis. The eperythrcrzoonsis may be spreaded by upright from mather to newborn.
