从实验感染的沙鼠腹腔内取得马来丝虫虫卵和微丝蚴,经固定、脱水、包埋、切片、染色后,在Philips 400T显微镜下检查。高倍下检查虫卵可清楚见到一层膜,在其表面具有微细电子密集阴影。逐步增大倍数,可见卵壳有二种结构:均匀的基膜和在其上有明显的电子密集阴影。电子密集阴影复盖着卵壳的整个表面,大小形状不一,一般基底宽,远侧变狭,最长为70nm。 Malayan eggs and microfilariae were obtained from the abdominal cavity of experimental infected gerbils and fixed, dehydrated, embedded, sectioned, stained and examined under a Philips 400T microscope. Check the eggs at high magnification can clearly see a layer of membrane, in its surface with a dense electron-dense shadow. Increasing the magnification gradually shows that the egg shell has two structures: a uniform basement membrane and a clear electron-dense shadow on it. The electron-dense shadow covers the entire surface of the egg shell, varying in size and shape, generally broad basal and distal narrowing, up to 70nm.
