Effects of Chicken Interferon Gamma on Newcastle Disease Virus Vaccine Immunogenicity. [PDF]
PLoS ONE, 2016 More effective vaccines are needed to control avian diseases. The use of chicken interferon gamma (chIFNγ) during vaccination is a potentially important but controversial approach that may improve the immune response to antigens.

RNA editing in Newcastle disease virus
Journal of General Virology, 1993 The co-transcriptional editing of the Newcastle disease virus (NDV) P gene has been studied by sequence analysis of cloned viral genomic RNA and mRNA. Evidence has been obtained for the specific insertion of non-templated G nucleotides, the consequence of which is the generation of three populations of P gene-derived mRNAs. The three populations encode

Strain differences in the Newcastle disease virus [PDF]
Journal of Hygiene, 1956 The biological characters of eight strains of the Newcastle disease virus, isolated in different parts of the world between 1933 and 1951, have been studied and compared in detail.Two types of the virus have been distinguished, one from the Newcastle disease prevalent in Europe and Australia, the other from that occurring in the United States of ...

Thermal Inactivation of Newcastle Disease Virus [PDF]
Applied Microbiology, 1970 The rate of destruction of hemagglutinins and infectivity of Newcastle disease virus was determined over a temperature range of 37.8 to 60 C. From the calculated values of δH and δS, it was concluded that inactivation of the hemagglutinating activity and viral infectivity was due to protein denaturation.

Analysis of some Epidemic Models in complex networks and some ideas about isolation strategies [PDF]
arXiv, 2021 Many models of virus propagation in Computer Networks inspired by {\bf SIS,SIR,}\\ {\bf SEIR}, etc. epidemic disease propagation mathematical models that can be found in the epidemiology field have been proposed in the last two decades. The purpose of these models has been to determine the conditions under which a virus becomes rapidly extinct in a ...

Noncytopathic mutants of Newcastle disease virus [PDF]
Journal of Virology, 1978 We have isolated a novel class of mutants of Newcastle disease virus which are less cytopathic than their virulent parent but are still capable of infectious virus production. Unlike wild-type virus, the mutants did not form plaques after 2 days of incubation; they did, however, make hemadsorbing spots.
