渤海湾虾蟹类的复殖吸虫

初步了天津渤海湾几种虾蟹寄生复殖吸虫的状况。其中日本大眼蟹（Ｍａｃｒｏｐｈｔｈａｌｍｕｓ ｊａｐｏｎｉｃｕｓ）体内已发现有２种吸虫囊呦,经体外培养,获得一种策茎科成虫－后睾异类茎吸虫（Ａｌｌｏｍｉｃｒｏｐｈａｌｌｏｉｄｅｓ ｏｐｉｓｔｈｏｒｒｃｈｉｓ）和另一种隐孔科侧孔吸虫（Ｐａｒａｇｏｎｏ ｓｐ．）的童虫。此项研究发现了后睾异类茎吸虫的中间宿主,囊蚴的形态和新的囊蚴分布区,进一步描述了侧孔吸虫的     

Endoparasites of the European ground squirrel (Spermophilus citellus) (Rodentia: Sciuridae) in central Macedonia,Greece

The European ground squirrel (Spermophilus citellus) is a small rodent categorized as vulnerable (IUCN). To investigate the parasitic fauna of this species in Greece, faecal samples from 125 animals belonging to six different populations were examined by standard parasitological methods. Parasites were found in 118 of the animals (94.4%). Oocysts of the coccidia Eimeria callospermophili were found in 92 animals (73.6%), Eimeria citelli in 76 (60.8%), Eimeria cynomysis in 41 (32.8%), Eimeria spp. (17.6%), Cryptosporidium spp. in 29 (23.2%), cysts of Entamoeba spp. in 32 animals (25.6%) and eggs of the trematode Brachylaima spp. in seven animals (5.6%). This is the first report of Entamoeba spp., Cryptosporidium spp. and Brachylaima spp. in S. citellus. The possible impact of these findings on the health status of S. citellus and the possible significance to domestic animals or public health is discussed.
