Cruoricola lates are found throughout sea bass (Lates calcarifer), most commonly in the mesenteric blood vessels, kidney, pericardial vessels, and eye. Eggs of C. lates were predominantly found in the gills, ventricle, hepatopancreas, and kidneys, but only develop to miracidia regularly in the gills and heart. Single miracidia escaping appear to cause little damage, but groups induce an inflammatory response and haemorrhage. Endocardial macrophages encapsulate eggs trapped between trabeculae in the heart. The reaction to eggs in the kidneys, hepatopancreas and spleen consists of fibrocytic encapsulation. Infection at the levels observed in this study were insufficient to cause lethal pathological changes, but could result in reduced food conversion ratios or impaired immunological capacity.
宽体吸虫（Cruoricola lates）在尖吻鲈（Lates calcarifer）体内各处均有发现，最常见于肠系膜血管、肾脏、心包血管和眼睛。宽体吸虫的卵主要见于鳃、心室、肝胰腺和肾脏，但仅在鳃和心脏中能正常发育成毛蚴。单个逸出的毛蚴似乎造成的损害很小，但成群的毛蚴会引发炎症反应和出血。心内膜巨噬细胞会包裹被困在心脏小梁间的虫卵。肾脏、肝胰腺和脾脏对虫卵的反应是纤维细胞包裹。本研究中观察到的感染水平不足以导致致命的病理变化，但可能会导致食物转化率降低或免疫能力受损。
