目的探讨附红细胞体的生物学特性.方法观察低温对附红细胞体活力的影响,附红细胞体感染异种动物试验,附红细胞体在动物体内消长测定试验.结果附红细胞体在-20 ℃下保存835 d,在4 ℃下保存205 d,仍有一定的活力;猪附红细胞体可以感染小白鼠而不能感染鸡;附红细胞体在动物体内变化的基本规律是在感染后,2-4 h RBC的感染率迅速上升到96%～98%,然后下降又上升,在感染后第8 h再次达到高峰,最后呈现周期性的上下波动,波动的基本周期是14-16 h.结论附红细胞在-20 ℃可以较长时间保持活力,对宿主有相对的种属特异性,感染动物后潜伏期短,在动物体内的繁殖周期是14-16 h.

Some biological properties of eperythrozoon, such as the influence of low temperature on their viability, their infectivity in different kinds of animals and their changes in amount of organisms in vivo were investigated in the present study. The experimental results showed that the viability of eperythrozoon could be maintained at -20 ℃ for 835 days and at 4 ℃ for 205 days. Small rats could be infected by Eperythrozoon suis, while chickens were not infected. The basic regulation on the changes in amount of organisms in animals was expressed by the fact that the percentages of erythrocytes being infected increased rapidly up to 96-98% 2-4 hours after infection, then it dropped down and followed by dropping and re-rising, attaining its climax up to 8 hours after infection. Finally, it reflected a fluctuating cycle of 14-16 hours. This results showed that eperythrozoons can maintain their viability at -20℃ for a long time and they possess relative species specificity to host with a reproduction cycle of 14-16 hours in animal body.
