摘要:   目的 观察猪带绦虫成虫孕节片含卵数量与成熟率。 方法 对 10条猪带绦虫成虫孕节末端 10个孕节片内虫卵进行计数并计算其成熟率。 结果与结论  10条猪带绦虫每节成熟孕节片内虫卵数量不等 ,悬殊较大 ,一个孕节片含卵数最高达 12 6 5 2 0个 ,最少 390 0个 ,平均 2 8332个。成熟率最高为 36 .0 % ,最低为 7.0 % ,平均为 2 9.1% ,较绦虫成虫自动脱落随患者粪便排出之孕节片内虫卵成熟率为低。另外 ,在适宜温度与湿度条件下 ,排出宿主体外的孕节片内虫卵仍可继续发育 ,2~ 3d后 ,成熟率可提高至 85 %~ 90 %。

Abstract:  Objective To investigate the number and mature rate of eggs in gravid proglottids of Taenia solium . Methods Ten worms of Taenia solium , expelled from patients, were detected. Eggs were collected from the last 10 gravid proglottids of each worm. Results & Conclusion The egg number in each mature proglottids varied from 3 900 to 126 520, and the mean number was 28 332. The mature rate of eggs was from 7.00% to 36.00% with an average of 29.12%, which was lower than that in proglottids naturally excreted with feces. With suitable temperature and humidity, the proglottids developed continually after excreted out of host body. Two to three days later, the mature rate of their eggs increased to 85%-90%.
