Cage-cultured sutchi catfish Pangasius hypophthalmus (Sauvage, 1878), a favourite food fish in Southeast Asia, proved to be infected by 6 myxozoan species. Three species belonged to the genus Hennegoides (H. berlandi, H. malayensis, and H. pangasii), 1 to Henneguya (H. shariffi) and 2 to Myxobolus (M. baskai, and M. pangasii). Five myxozoans infected the gills and 1 was found on the spleen. Myxozoans infecting the gills were characterised by a specific site selection. H. shariffi sp. n. and H. berlandi sp. n. formed plasmodia in the multi-layered epithelium of the gill filaments. Of the 2 vascular species H. pangasii sp. n. developed in the gill arteries, while M. baskai sp. n. infected the capillary network of the gill lamellae. Plasmodia of H. malayensis sp. n. were found inside the cartilaginous gill rays of the filaments. Large plasmodia of M. pangasii sp. n. were located in a groove of the spleen but they affected only the serosa layer covering the spleen.
网箱养殖的苏氏圆腹芒鲶（Pangasius hypophthalmus，萨瓦奇，1878年）是东南亚一种受欢迎的食用鱼，已证实感染了6种粘孢子虫。其中3种属于亨内戈伊德属（Hennegoides berlandi、H. malayensis和H. pangasii），1种属于尾孢虫属（Henneguya shariffi），2种属于粘体虫属（Myxobolus baskai和M. pangasii）。5种粘孢子虫感染鳃，1种在脾脏中发现。感染鳃的粘孢子虫具有特定的位点选择特征。新种沙氏亨内戈伊德虫（Henneguya shariffi sp. n.）和新种伯氏亨内戈伊德虫（Hennegoides berlandi sp. n.）在鳃丝的多层上皮中形成孢囊。在2种血管寄生的粘孢子虫中，新种苏氏亨内戈伊德虫（Hennegoides pangasii sp. n.）在鳃动脉中发育，而新种巴氏粘体虫（Myxobolus baskai sp. n.）感染鳃小片的毛细血管网。新种马来亚亨内戈伊德虫（Hennegoides malayensis sp. n.）的孢囊在鳃丝的软骨鳃条内发现。新种苏氏粘体虫（Myxobolus pangasii sp. n.）的大型孢囊位于脾脏的一条沟中，但仅影响覆盖脾脏的浆膜层。
