研究了生活在日本3个淡水生物区泥中的寡毛虫对放线孢子的感染情况。用细胞孔板方法，在富士山山梨县渔业试验站附近的溪流中发现了一种新的放线菌类型，占所检出的少毛管藻类标本的0.77%。在采集于几糖鲑鱼孵化场附近几托斯河的变种轮虫中，有0.14%的变种中发现了一种新的变种类型，同时也有8.1%的变种被发现。寡毛虫释放出北极粘球藻的三放线菌体。在采自北海道梅纳河水系的komarovi寡毛Rhyaco drilus中，0.2%、0.6%、0.5%和0.8%分别感染棘细胞放线菌、新放线菌和两种类型的三放线菌孢子。寡毛虫释放放线孢子达数周之久。所有放线孢子菌的阳性寡毛菌的放线孢子感染强度都很高。这里提出的两种放线孢子类型(放线菌和西德莱基菌)以前从未被描述过。
Actinospore infection of oligochaetes living in the mud of 3 freshwater biotopes in Japan was studied. Using the cell-well plate method, a new aurantiactinomyxon type was found in 0.77% of the examined Tubifex tubifex oligochaete specimens from a brook near Yamanashi Prefectural Fisheries Experimental Station on Fuji Mountain. In 0.14% of Lumbriculus variagetus collected from Chitose River, near Chitose Salmon Hatchery, a new siedleckiella type was found, while at the same time 8.1% of the Lumbriculus spp. oligochaetes released triactinomyxons of Myxobolus arcticus. Of the examined Rhyacodrilus komarovi oligochaetes collected from the Mena River system, Hokkaido, 0.2, 0.6, 0.5 and 0.8% were infected with echinactinomyxon, neoactinomyxum and 2 types of triactinomyxon spores, respectively, and described in our previous paper. The oligochaetes released actinospores for several weeks. Actinospore infection showed high intensity in positive oligochaetes in the case of all the actinosporean types. Two of the actinospore types (aurantiactinomyxon and siedleckiella) presented here have not been previously described.
