摘　　要：采用石蜡切片技术,分别制作未感染蚌螨卵或已感染蚌螨卵褶纹冠蚌的外套膜、鳃、斧足、唇瓣、水管5种组织的切片,并进行显微观察与比较。结果显示,未受感染的蚌体内,各组织的上皮细胞排列整齐,结缔细胞分布均匀;而在受感染的蚌体内,各组织的上皮细胞排列不整齐,且在蚌螨卵的寄生部位周围形成一个致密的包囊,从而使其周边的组织受到压迫,上皮与结缔细胞变形。表明蚌螨卵的感染对褶纹冠蚌的多种组织造成了病理损伤,从而发生了明显的病理变化。In the present paper, the histopathological effect of Unionicola arcuata eggs on different tissues in Cristaria Plicata was studied by comparing five tissues, including mantle, gill, foot, labial palpus and water pipe as well, between healthy （uninfected） and ill （infected） bivalve using the wax section technology. Results showed that in tissues of the healthy bivalve, epithelial cells arrange in normal order and connective tissues distribute homogeneously, while in ill bivalve, a compact cyst was found to form around eggs, making its peripheral tissues be pressed and epithelial or connective cells be out of shape, and to several different tissues hemocytes be aggregated. It＇ s suggested that U. arcuata eggs be harmful of C. plicata, and lead to certain obvious histopathological effect on them.
