Studies on Newcastle Disease Virus
1. It is likely that certain tailed and filamentous particles seen on electron microscope examination of partially purified saline suspensions of Newcastle virus are the individual virus particles because: (a) They have a highly characteristic shape not seen in other virus preparations. (b) They are present whenever the virus is present in high concentration. (c) Their size agrees with the size...
متن کاملStudies on Newcastle disease virus by the plaque method.
The establishment of a successful plaque method for counting infectious virus particles by Dulbecco (1952), with subsequent refinements by Dulbecco and Vogt (1953, 1954a), makes it possible to quantitatively assay animal viruses with a high degree of accuracy in a manner comparable to assays of bacterial viruses. Two methods of assay commonly used in characterizing any particular Newcastle dise...
متن کاملVirulence of newcastle disease virus: what is known so far?
In the last decade many studies have been performed on the virulence of Newcastle disease virus (NDV). This is mainly due to the development of reverse genetics systems which made it possible to genetically modify NDV and to investigate the contribution of individual genes and genome regions to its virulence. However, the available information is scattered and a comprehensive overview of the fa...

Circulating Interferon Induced by Newcastle Disease Virus
Circulating interferon production, induced by Newcastle disease virus, is about seven times higher in C57 Black mice than in Balb/c/Gif mice. A Mendelian analysis was carried out and circulating interferon production was measured in reciprocal F1 hybrids, in the F2 generation, in progeny of backcrosses of F1 hybrids to either parent strain, and in second backcross progeny. The results indicate ...
