Isolation and Properties of Newcastle Disease Virus Nucleocapsid

Nucleocapsid protein subunits of simian virus 5, Newcastle disease virus, and Sendai virus.

Helical nucleocapsids of each of the paramyxoviruses simian virus 5 (SV5), Newcastle disease virus (NDV), and Sendai virus have been isolated in two different forms. One form contains larger protein subunits and is obtained from mature virions or infected cells dispersed by ethylenediaminetetraacetic acid. The other form possesses smaller subunits and is obtained from infected cells dispersed b...

Delay in the incorporation of protein into virus nucleocapsid in Newcastle disease virus infected cells.

In cells infected with paramyxovirus progeny 50 S RNA seems to be incorporated immediately into the nucleocapsid (Blair & Robinson, I97o). There has been no report of any attempt to estimate the time interval between the synthesis of a molecule of nucleocapsid protein and its incorporation into the structure of the nucleocapsid. In the experiments described in this paper the problem has been ap...

Studies on the immunogenic properties of three lentogenic strains of newcastle disease virus

Isolation of herpes simplex virus nucleocapsid DNA.

As an inanimate virus, herpes simplex virus type 1 (HSV-1) necessarily encodes all of its functions in its DNA. Isolation of pure viral DNA allows multiple downstream applications, including the creation of recombinant HSV strains, cloning of selected regions, and sequencing of viral DNA. The term nucleocapsid refers to the combination of the viral genome with the enclosing capsid; these viral ...

Isolation and pathogenicity identification of avian paramyxovirus serotype 1 (Newcastle disease) virus from a Japanese quail flock in Iran

Newcastle disease virus (NDV) was isolated and identified for the first time from a flock of Japanese quail suspected to ND in Iran. Birds of the flock aged variously, and some of them died from the disease. Loss of appetite, weakness and decrease in egg production, diarrhea and nervous symptoms were the main clinical signs in the birds. Hemorrhagic lesions of the intestinal tracts and proventr...
