Abstract
A virus is associated with a strain of transovarially-transmitted SR-spirochetes, NSR, of Drosophila. This virus, designated spv-1, is able to infect and to multiply in another strain of SR-spirochetes, WSR, thereby eliminating the SR condition from the host flies. Spv-1 contains DNA, has a buoyant density of 1.480 in CsCl, and is spherical in shape, measuring 50-60 nm in diameter.
摘要
一种病毒与果蝇经卵传播的SR螺旋体菌株NSR有关。这种病毒被命名为spv - 1，能够在另一种SR螺旋体菌株WSR中感染并繁殖，从而使宿主果蝇消除SR状态。Spv - 1含有DNA，在氯化铯中的浮力密度为1.480，呈球形，直径为50 - 60纳米。
