pubmed:abstractText |
Varicella-zoster virus (VZV) DNA was prepared from nucleocapsids and from enveloped virions of a laboratory strain (Ellen) and directly from the vesicle fluids of patients with zoster infections. VZV Ellen nucleocapsid DNA was cleaved with 11 different restriction endonucleases and electrophoresed in agarose gels. The restriction profiles of the nucleocapsid DNA were identical to those of the DNA recovered from purified virions, but differed from those of another VZV strain (KM). In vitro-labeled VZV K.M. DNA purified directly from vesicle fluid yielded a distinct restriction pattern which appeared to be unchanged after several tissue culture passages of the isolate from that fluid. Restriction endonuclease analysis (EcoRI or BglII) of VZV DNA revealed the presence of four cleavage fragments with a molar ratio of approximately 0.5. No individual fragments with molar ratios of 0.25 were noted. This observation suggests that the VZV genome may contain one invertible segment. Comparison of the electrophoretic migrations of VZV DNA fragments relative to those of DNAs of known size permitted calculation of the VZV genome size to be 72 X 10(6) to 80 X 10(6) daltons. These results were confirmed by electron microscopy which demonstrated a genome size of about 76 X 10(6) daltons for passaged and unpassaged VZV DNA. Electron microscopy also revealed that some of the DNA molecules recovered from nucleocapsids or directly from vesicle fluids were superhelical circles.
