Abstract

Summary

The replication of rodent parvovirus X14 DNA has been studied in rat embryo tissue culture cells. Virus DNA was isolated from 1 -NaCl-SDS-pronase supernatant fluids from 24 h after infection. The majority of this DNA was 1.7 µm in length and double-stranded, indicating that it was an intermediate in the replication cycle of this single-stranded DNA virus. Single-stranded DNA of equivalent length was isolated directly from X14 virions. The buoyant density of this DNA was 1.728 g/ml whereas the double-stranded form banded at 1.714 g/ml in caesium chloride gradients. Difficulties in detecting significant amounts of single-stranded viral DNA directly from infected cells would appear to indicate that progeny single-stranded DNA is rapidly encapsidated after synthesis.
