宿主体内的丝虫成虫与微丝蚴一般很难直接观察。作者用视屏显微镜(带有照像系统的Olympus高倍解剖镜或Olympus高倍倒置显微镜,放大倍数是×25～×66)观察了雪貂体内马来丝虫的活动与形态。在雪貂两侧腹股沟皮下注入马来丝虫感染期幼虫,几个月后从后趾皮内注射伊文氏蓝,手术暴露其后肢大腿与腘部淋巴结间肿胀的淋巴管,在高倍视屏显微镜下观察到虫体在淋巴管内左右摆动;将淋巴管双侧结扎切下,亦可见丝虫通过淋巴管的瓣膜来回移动,切开管
Host filarial adults and microfilaria adults are generally difficult to observe directly. The authors observed the activity and morphology of the malaria filariasis in a ferrets using a microscope (Olympus High-Power Disposing Microscope with a camera system or Olympus High-Power Inverted Microscope, magnification × 25 to × 66). In the ferrets on both sides of the groin subcutaneous injection of Malayi infection larvae, a few months after the injection of Evans blue from the hind-toe, surgical exposure of the hind limb thigh and lymph nodes lymph nodes between the lymph nodes under high magnification microscopy Observed parasites in the lymphatic vessels around the swing; the bilateral ligation of the lymphatic vessels cut, also saw the filariasis through the lymphatic valve back and forth movement, open the tube
