受检者张××,于1979年11月9日夜11时取耳垂血3滴,制成厚血膜。自然干燥。次日上午11时许用自来水溶解红细胞后镜检见一活微丝蚴,似蛇样运动,甚活跃。半小时后随血膜上自来水干涸而呈自然弯曲状态死亡。该蚴经有关部门检定为马来微丝蚴。微丝蚴在人体的寿命约为2～3个月,在体外4℃时可活1个半月左右,在干血膜中一般均死亡。然而此例微丝蚴在血膜自然干涸12个小时后,在水中仍然复活。这可能因血膜未干透,且气温较低,个别微丝蚴幸存。但此例甚为少见。
The subject Zhang × ×, at 11 o’clock on the November 9, 1979 ear lobes 3 drops, made of thick blood film. Natural dry. 11 am the next day with red blood cells dissolved in water after microscopy see live microfilaria, like a snake like exercise, very active. Half an hour later with the dry blood on the membrane and the natural bent state death. The larvae by the relevant departments for the detection of Malay microfilaria. Microfilaria in the human life expectancy of about 2 to 3 months, 4 ℃ in vitro can survive about 1 and a half months, the general death in the dry blood film. However, this case microfilariae naturally dried up in the blood 12 hours after the water is still alive. This may be due to blood film is not dry, and the temperature is low, individual microfilariae survived. But this case is very rare.
