Abstract

The peritoneal cavity of laboratory mice was used to study the phenomenon of host cell adhesion to different evolutive stages of the Schistosoma mansoni (cercaria, adult worm, developing and mature eggs, miracidium, young and mature daughter sporocysts). Material recovered from the peritoneal cavity 30 and 180 min after the inoculation of each evolutive form was examined with the help of a stereomicroscope. The free swimming larvae (cercaria and miracidium), and the evolutive forms producing such larvae (mature egg and mature daughter sporocyst) elicited the host cell adhesion phenomenon. In all forms but cercariae the adherent cells remained as so till 180 minutes after inoculation.

摘要

利用实验室小鼠的腹腔来研究宿主细胞与曼氏血吸虫不同发育阶段（尾蚴、成虫、发育中和成熟的虫卵、毛蚴、幼嫩和成熟的子胞蚴）的黏附现象。在接种每种发育形式后的30分钟和180分钟，从腹腔中回收的材料借助体视显微镜进行检查。自由游动的幼虫（尾蚴和毛蚴）以及产生此类幼虫的发育形式（成熟虫卵和成熟子胞蚴）引发了宿主细胞黏附现象。除尾蚴外，在所有形式中，黏附细胞在接种后180分钟内都保持这种状态。
