An examination of the occurrence of crystalline inclusions in the intestinal cells of fourth and fifth stage Haemonchus contortus revealed that a high percentage of inhibited early fourth stage larvae (L4) and developing L4 and a lower percentage of early fifth stage larvae (L5) harboured these crystals. Before the fourth moult crystals were falling into pieces, indicating that worms harbouring crystals can develop further. The presence of crystals may be associated with a retardation of development.
对第四和第五阶段捻转血矛线虫肠道细胞中晶体包涵体的出现情况进行检查发现，高比例的受抑制早期第四阶段幼虫（L4）和发育中的L4以及较低比例的早期第五阶段幼虫（L5）含有这些晶体。在第四次蜕皮之前，晶体破碎，这表明含有晶体的蠕虫可以进一步发育。晶体的存在可能与发育迟缓有关。
