TLDR
Poultry products contaminated with pathogenic strains of Newcastle disease virus are a source of virus transmission to susceptible poultry flocks and feathers, bones, blood and offal present potential risks if they are incorporated in poultry feed.Abstract:
Poultry products contaminated with pathogenic strains of Newcastle disease virus are a source of virus transmission to susceptible poultry flocks. The probability of contamination varies according to the type of product. Research conducted by various laboratories in Europe has shown that pathogenic virus can be isolated from the carcasses of chickens, whether vaccinated or not, during a brief period after experimental infection. Eggs laid by hens infected with Newcastle disease virus present a very low risk. Furthermore, feathers, bones, blood and offal present potential risks if they are incorporated in poultry feed. Finally, poultry droppings used as a fertiliser can present a major risk of infection in certain circumstances.read more

Newcastle disease virus (strain Herts 33/56) in tissues and organs of chickens infected experimentally.
TL;DR: Six-week-old susceptible specific pathogen free chickens were infected intranasally with the virulent Newcastle disease virus strain Herts 33/56 and the levels of virus present in blood, faeces, breast muscle, leg muscle and a pool of heart/kidney/spleen were estimated in birds killed humanely at each day post inoculation.

A survey of Newcastle disease in Swiss laying-hen flocks using serological testing and simulation modelling.
TL;DR: Computer simulation was a useful technique to interpret survey results and indicates that Swiss laying-hen and parental flocks with more than 150 animals have been in contact with strains of NDV that cause subclinical infection in chicken, because no clinical symptoms have been observed.

TL;DR: In this paper, a model of transmission of the virus of the maladie de Newcastle (VMN) is presented, based on connaissances actuelles de l'histoire naturelle of the transmission.

Newcastle disease outbreaks in fowl in Great Britain during 1984
TL;DR: Use of available mouse monoclonal antibodies enabled unequivocal identification of the virus responsible for 22 of the outbreaks as similar to the avian paramyxovirus type 1 (A/PMV-1) virus causing neurotropic disease in pigeons during 1983 and 1984.

TL;DR: The object of the present chapter is to cover the transmission and spread of the disease and virus rather than every parameter associated with the epizootiology of ND.
