【摘要】 检查10份蛲虫卵标本的2000个虫卵,含蚴卵1483个,占检查总数的74.15％,蝌蚪期卵503个,占25.15％,蚴虫脱壳卵4个,占0.2％,死卵10个,占0.5％。人工孵化后,10份标本的2000个虫卵中,具活性卵1207个,占检查孵总数的60.35％,蚴虫脱壳卵767个,占38.35％,死卵26个,占1.3％。实验表明,绝大多数虫卵自成虫产出后,具有较强的生活力和感染力。更多还原

【Abstract】 2000 eggs were examined in 10 samples of E.vermicularis eggs laid naturally Out of them 1483 eggs were infective eggs at a rate of 74.l5%,503pof them were embryonated eggs at a rate of 25.15%, 4 of them were shed eggs at a rate of 0.2%,and 10 of them were dead eggs at a raet of 0.5%.After artificia incubation,2000 eggs were obtained 10 samples of E.vermicularis eggs,including 1207 active eggs ( 60.35% ) ,767 shed eggs ( 38.35% ), and 26 dead eggs (1.3%).It is concluded that most of E.vermicularis eggs has a powerful viability and infectivity.更多还原
