菲律宾蛤仔帕金虫病组织病理学研究

对被帕金虫perkinsus sp孢子体感染的菲律宾蛤仔Ruditapes philippinarum主要器官的组织学观察发现，帕金虫孢子体主要寄生于结缔组织中，绝大多数被嗜酸性颗粒细胞包裹，在锶，外套膜，消化管中帕金虫孢子体的数量多，在闭壳肌，出水管中的少，足中尚未发现，孢子体的形状多样，成熟的营养孢子体有一个大液泡，被帕金虫孢子体寄生的组织，表现出程度不同的病理学变化，严重的情况下，结缔组织中游离和寄生的孢体的数量很多，上皮细胞核固缩，坏死，细胞脱落。

Histopathological study on Perkinus sp. disease of Ruditapes philippinarum

The histology of the main organs of the infected Ruditapes philippinarum was observed with light micrscope. The trophozoite, enveloped by eosinophil pactical cells, predominantly had parasited in the connective tissue. They were also frequently found in gill, mantle and digestive tract, but rarely in adductor muscle and efferent siphon, and not in podium. Trophozoites occurred in various forms. The mature trophozoite possessed a large vacuole. Pathological changes appeared in different degrees in the tissues infected by trophozoite. In serious case the amount of trophozoite increased and the epithelium was shrunk, necrotic and decomposed.
