Abstract—

The cytomorphological composition of the blood and mesonephros of goldfish infected with Ligula interrupta has been studied under the conditions of the native range. A decrease in the total number of leukocytes and neutrophils in the blood at all stages of development and deregulation of the proliferation and differentiation of lymphoid, pseudo-eosinophilic, and pseudo-basophilic elements in the studied organs are established. Infiltration of neutrophilic mesonephros by low-differentiated forms is observed. It has been shown that, in this parasitic system, the partner relations cause the launch by L. interrupta of mechanisms that regulate the host immune response by inhibiting the acute inflammatory response and the development of mild chronic inflammation. B-cell activation in the immune response is accompanied by processes of cellular degeneration and immunosuppression, factors that are actively involved in cytotoxic reactions.

金鱼的血液和中肾的细胞形态学变化感染了间断舌虫（Cestoda：Pseudophyllidea）

摘要—

血液和金鱼感染的中肾的细胞形态学组成Ligula interrupta已在本地范围内的条件下研究。在研究器官的淋巴，假嗜酸性和假嗜碱性元素的发育和失调的所有阶段，血液中白细胞和嗜中性粒细胞总数的减少都被确定。观察到低分化形式的中性粒细胞浸润。已经表明，在这种寄生系统中，伙伴关系导致了中断乳杆菌的发射。通过抑制急性炎症反应和轻度慢性炎症的发展来调节宿主免疫反应的机制。免疫反应中的B细胞活化伴随着细胞变性和免疫抑制过程，而这些都是积极参与细胞毒性反应的因素。
