Morphogenesis of Trichostrongylus rugatus was examined in 16 sheep experimentally-infected with 120 000 third-stage larvae and killed 2, 4, 6, 8, 10, 12, 16 and 20 days later (DAI). Third stage larvae moulted between Days 4 and 6, and fourth stage larvae moulted on Day 10 after infection. Four sheep first passed eggs in the faeces between Days 16 and 18 after infection. Rate of growth of larvae was constant between 2 and 10 DAI followed by a period of rapid growth from 10 to 16 DAI. Major features of larval development are described. Nematodes were largely restricted to the first 6 m of gut with 71% of worms occurring in the first 3 m.
对16只实验感染120000条三期幼虫的绵羊进行了皱毛圆线虫的形态发生研究,并在感染后2、4、6、8、10、12、16和20天(DAI)将其处死。三期幼虫在第4至6天之间蜕皮,四期幼虫在感染后第10天蜕皮。4只绵羊在感染后第16至18天之间首次在粪便中排出虫卵。幼虫在2至10 DAI之间生长速度恒定,随后在10至16 DAI之间快速生长。描述了幼虫发育的主要特征。线虫主要局限于肠道的前6米,71%的虫体出现在前三米。
