The infective juveniles of Trichostrongylus colubriformis can survive exposure to 0% relative humidity after desiccation at higher relative humidities. During rehydration there is a lag phase before recovery. The infective juveniles are thus capable of anhydrobiosis. Removal of the sheath does not affect desiccation survival but does affect the duration of the lag phase. Morphological changes during the lag phase are described. The appearance of birefringence in the muscle cells during the anomalous shrinkage which occurs during the lag phase is considered to reflect physiological changes necessary for the recovery of normal muscle function.
蛇形毛圆线虫的感染性幼虫在较高相对湿度下干燥后，能够在暴露于0%相对湿度的环境中存活。再水化过程中有一个恢复前的滞后期。因此，感染性幼虫能够进行脱水生物状态。去除鞘膜不影响干燥存活，但会影响滞后期的持续时间。描述了滞后期的形态变化。滞后期出现的异常收缩过程中肌肉细胞双折射的出现被认为反映了恢复正常肌肉功能所需的生理变化。
