The larval development of Muellerius cf. capillaris in aestivating Trochoidea seetzenii and Theba pisana was delayed: in the first snail 82% of the parasites remained as second-stage larvae (L2) after as much as 90 days, and in the second snail 60% remained as L2 after 50 days. Reactivation of T. seetzenii after 59 days of aestivation caused the larvae to develop to the third stage (L3). The number of recovered larvae among T. seetzenii was consistently higher in active vs aestivating snails (P < 0.05). Such differences were not evident among T. pisana (P > 0.05). In active T. pisana, larval development was faster than in active T. seetzenii, whereas there were no such differences between aestivating snails of these 2 species. Aestivating infected T. seetzenii had lower body weights than same-size active non-infected, as well as infected snails. Aestivating infected T. pisana were not weighed, but they too exhibited poor body condition.
在夏眠的赛氏 Trochoidea seetzenii 和埃及沙漠蜗牛 Theba pisana 中，毛细缪勒线虫（Muellerius cf. capillaris）的幼虫发育延迟：在第一只蜗牛中，多达90天后，82% 的寄生虫仍处于第二阶段幼虫（L2），在第二只蜗牛中，50天后60% 仍为L2。夏眠59天后赛氏 Trochoidea seetzenii 的重新激活使幼虫发育到第三阶段（L3）。活动状态的赛氏 Trochoidea seetzenii 中回收的幼虫数量始终高于夏眠状态的蜗牛（P < 0.05）。在埃及沙漠蜗牛 Theba pisana 中这种差异不明显（P > 0.05）。在活动状态的埃及沙漠蜗牛 Theba pisana 中，幼虫发育比活动状态的赛氏 Trochoidea seetzenii 更快，而在这两个物种的夏眠蜗牛之间没有这种差异。夏眠感染的赛氏 Trochoidea seetzenii 的体重低于相同大小的活动状态未感染蜗牛以及感染蜗牛。未对夏眠感染的埃及沙漠蜗牛 Theba pisana 称重，但它们的身体状况也很差。
