摘　　要：为掌握贝类帕金虫病的发生和流行规律,对广西沿海的常见贝类进行了帕金虫(Perkinsus spp.)感染情况调查,并开展了香港巨牡蛎(Crassostrea hongkongensis)和菲律宾蛤仔(Ruditapes philippinarum)寄生帕金虫的流行病学研究。结果显示,调查的14种贝类中有13种感染了奥尔森帕金虫(P. olseni),8种感染了北海帕金虫(P. beihaiensis),7种同时感染了这2种帕金虫(同一贝类个体最多感染一种帕金虫)。奥尔森帕金虫在尖紫蛤(Soletellina acuta)、棕带仙女蛤(Callista erycina)、菲律宾蛤仔、毛蚶(Scapharca subcrenata)等4种贝类中的感染率显著高于其他10种,而北海帕金虫在香港巨牡蛎和翡翠贻贝(Perna viridis)中的感染率显著高于其他12种。在香港巨牡蛎中,北海帕金虫的感染率显著高于奥尔森帕金虫;在菲律宾蛤仔中,奥尔森帕金虫的感染率显著高于北海帕金虫。帕金虫在不同海域、不同养殖贝类种类中呈现出不同的感染规律。In order to clarify the occurrence and epidemic rule of Parkin's disease in shellfish,we investigated the infection of parasitic protozoa(Perkinsus spp.)on the common shellfish hosts along the coastal area of Guangxi Province,and studied the epidemiology of Perkinsus spp.on two locally cultured bivalves(Crassostrea hongkongensis and Ruditapes philippinarum).The results show that among the 14 investigated shellfish species,13 were infected by P.olseni,8 by P.beihaiensis,and 7 by P.olseni and P.beihaiensis at the same time(the same type of shellfish was at most infected with one kind of parasitic protozoa).The prevalence of P.olseni in Soletellina acuta,Callista erycina,R.philippinarum and Scapharca subcrenata was significantly higher than that in the other 10 species.The prevalence of P.beihaiensis in C.hongkongensis and Perna viridis was significantly higher than that in the other 12 species.The prevalence of P.beihaiensis was significantly higher than that of P.olseni in C.hongkongensis.The prevalence of P.olseni was significantly higher than that of P.beihaiensis in R.philippinarum.The prevalence of Perkinsus spp.varied in different shellfish species and coastal areas.
