Micromorphology and ultrastructure of capsule forming around acanthocephalan Corynosoma strumosum in uncommon paratenic hosts-lizards Lacerta agilis and Lacerta viridis-have been studied. Experimental infestation of the lizards by acanthocephalans obtained from naturally infested sea fishes showed that only small amount of parasites occurred in the intestine of the host was able to migrate into body cavity and to be encapsulated. Micromorphology of capsules of different ages from different species of lizards and micromorphology and ultrastructure of capsules at the age of 1.5 and 10 days appeared to be similar. In the capsule's structure cells of inflammatory rank were prevailing: mononuclear and multinuclear macrophages, eosinophils, and basophils. Fibroblasts were not numerous and were located only in the outer part of a capsule; exocellular collagen fibers were absent. Inflammatory character of capsule confirms the idea that lizards are unsuitable paratenic hosts for corynosomes.
已研究过棘头虫科棘头虫在不常见的副宿主蜥蜴（蜥蜴属和绿蜥蜴属）中形成囊的微观形态和超微结构。对从自然感染海鱼中获得的棘头虫对蜥蜴进行的实验感染表明，只有少量寄生虫能够从宿主的肠道迁移到体腔并被包裹。来自不同蜥蜴物种的不同年龄的囊的微观形态以及年龄为 1.5 天和 10 天的囊的微观形态和超微结构似乎相似。在囊的结构中，炎症级别的细胞占主导地位：单核和多核巨噬细胞、嗜酸性粒细胞和嗜碱性粒细胞。成纤维细胞数量不多，仅位于囊的外部分；细胞外胶原纤维不存在。囊的炎症特征证实了蜥蜴不适合作为棘头虫的副宿主的观点。
