Histological examination of the small intestine of mice infected with Heligmosomoides polygyrus indicates that the final site of the larvae is in the circular muscle layer of the muscularis externa of the anterior small intestine. The larvae become embedded in the muscle between the first and third days after infection and are subsequently sequestered by a localized leucocytic response. There is no evidence of a true cyst. Histological evidence suggests that the larvae actively feed on the tissues of the host during their development.
对感染多枝旋毛虫的小鼠小肠进行组织学检查表明，幼虫的最终寄生部位是小肠前部外肌层的环形肌层。幼虫在感染后的第一至三天内嵌入肌肉，随后被局部白细胞反应隔离。没有证据表明存在真正的囊肿。组织学证据表明，幼虫在发育过程中积极摄取宿主组织。
