The inter- and intralamellar types of Henneguya exilis Kudo (Myxosporida) infections from channel catfish are similar in spore structure and sporogenesis, but differ in the structure of their plasmodium wall and surface coat and in their relationship with the host cells. The 2 clinical types differ also in the sites of development and growth patterns of plasmodia within a gill filament. Interlamellar plasmodia are limited by 2 outer unit membranes which give rise to both single-and double-membraned pincytic canals. Intralamellar plasmodia are limited by a single outer unit membrane which gives rise to single-membraned pinocytic canals. Interlamellar plasmodia are covered by a fine granular coat of highly variable thicknesses; in some regions there is direct contact between the parasite and cells of the host. There is some evidence that host cell cytoplasm as well as interstitial material are taken in by interlamellar plasmodia. In contrast, intralamellar plasmodia are covered by a fine granular coat of almost uniform thickness, which prevents direct contact between the parasite and cells of the host; probably only interstitial material is taken by these plasmodia.
来自沟鲶的微小亨内氏黏体虫（黏孢子虫）的层间型和层内型感染在孢子结构和孢子发生方面相似，但在其疟原虫壁和表面被膜的结构以及与宿主细胞的关系方面存在差异。这两种临床类型在鳃丝内疟原虫的发育部位和生长模式上也有所不同。层间疟原虫由两层外单位膜限制，这两层膜会形成单膜和双膜的胞饮管。层内疟原虫由一层外单位膜限制，该膜会形成单膜的胞饮管。层间疟原虫被一层厚度变化很大的细颗粒被膜覆盖；在某些区域，寄生虫与宿主细胞直接接触。有证据表明，层间疟原虫摄取宿主细胞的细胞质以及间质物质。相比之下，层内疟原虫被一层厚度几乎均匀的细颗粒被膜覆盖，这阻止了寄生虫与宿主细胞的直接接触；这些疟原虫可能只摄取间质物质。
