(1) E. multilocularis and (2) E. granulosus. E. multilocularis, originating in the Arctic, is spreading southwards and has reached Saskatchewan and the Dakotas. The original hosts are foxes but dogs and cats are alternatives. The larvae occur in field mice as multilocular microcysts containing numerous protoscolices, but in man the cysts are alveolar and sterile and resemble both in histology and growth a cholangiocellular carcinoma of the liver with metastases. Signs and symptoms are chronic and poorly defined. Diagnosis is difficult. Test antigens are not yet satisfactory. E. granulosus has a sylvatic cycle, the adult tapeworms living in wolves and dogs, while the larvae occur only in Cervidae and man. The cysts occur almost exclusively in the lungs as unilocular, macrocystic, relatively benign tumours, although abnormal complications can occur. The Casoni intradermal sensitivity test, its technique and interpretation are discussed.
（1）多房棘球绦虫和（2）细粒棘球绦虫。原产于北极地区的多房棘球绦虫正在向南扩散，已到达萨斯喀彻温省和达科他州。其原始宿主是狐狸，但狗和猫也是中间宿主。幼虫寄生于田鼠体内，形成含有许多原头节的多房微囊肿，但在人体内，囊肿呈肺泡状且无菌，在组织学和生长方面类似于伴有转移的肝胆管细胞癌。症状是慢性的且不明确。诊断困难。检测抗原尚不令人满意。细粒棘球绦虫有一个野生动物循环，成虫绦虫寄生于狼和狗体内，而幼虫仅见于鹿科动物和人体内。囊肿几乎仅发生于肺部，为单房、大囊状、相对良性的肿瘤，不过也可能出现异常并发症。文中讨论了卡索尼皮内敏感试验、其技术及解读。
