By ciliates category Ichthyophthirius multifiliis parasitic on the gills of fish form and could pose.
由纤毛虫类的小瓜虫寄生于鱼体表及鳃内引起。
Inflammatory processes are known to take place in the skin of fish during an infection with the parasitic ciliate Ichthyophthirius multifiliis.
题目：感染小瓜虫的虹鳟鱼促炎细胞因子的表达。
The immobilization antigenof Ichthyophthirius multifiliisis primarily a protective antigen, which was of great importance in inducing host to produce the protective immunity, and it was also the primarily candidated antigen for the development of Ichthyophthirius multifiliis vaccines.
抑动抗原是小瓜虫的主要保护性抗原之一，在诱导宿主产生保护性免疫方面具有重要的作用，是研制小瓜虫疫苗的主要侯选抗原。
After Ichthyophthirius multifiliis infection, the expression of T-bet, GATA-3, HCK, LCK and CD8α in thymus and headkidney was mainly upregulated in 1-3d after infection, the expression of GATA-3 and HCK in skin was mainly up-regulated in 3-4d, and indicates that T cell immunity is related to anti-parasite infection.
而在小瓜虫感染条件下，LCK、HCK、T-bet、GATA-3和CD8α基因在1-3天鲤胸腺和头肾以上调表达为主；HCK、GATA-3基因在3-4天皮肤以上调表达为主；提示T细胞系统与鱼类抗寄生虫免疫密切相关。

The general structural organization of the pellicles resembles that of the freshwater holotrich Ichthyophthirius multifiliis, consisting of three membranes: outer limiting membrane, the outer alveolar membrane and the inner alveolar membrane.
刺激隐核虫质膜的基本结构与淡水的多子小瓜虫的质膜相似，分为3层：外限制膜、外胞膜和内胞膜。
Fish acquire protectie immunity against the ciliated protozoan parasite Ichthyophthirius multifiliis following sublethal infection or inoculation with I. multifiliis immobilization antigens. In both cases, parasite-immobilizing antibodies hae been identified in sera and mucosal secretions.
斑点叉尾鮰感染亚致死剂量的小瓜虫或接种小瓜虫抑动抗原（注射纯化的抑动抗原5μg/尾加弗氏不完全佐剂）后，获得了对小瓜虫的保护性免疫，而且在血清和粘膜分泌物中都检测到小瓜虫抑动抗体。
