Newcastle disease
Newcastle disease is a severe, systemic, and fatal viral disease of poultry due to virulent strains of avian paramyxovirus type 1. Clinical signs in unvaccinated birds include sudden death, lethargy, and respiratory distress. Diagnosis is based on laboratory confirmation. Vaccines prevent clinical signs but not infection, and the control of the disease is challenging in enzootic regions. Newcastle disease (ND) is an infection of domestic poultry and other bird species with virulent Newcastle disease virus (NDV). Newcastle disease is not a food safety or public health concern. Virulent NDV is capable of producing a devastating disease in domestic fowl, with vast social and economic consequences. It is a worldwide problem that presents primarily as an acute respiratory disease; however, depression, nervous signs, or diarrhea may be the predominant clinical form. Severity of ND depends on the virulence and genetic type of the infecting virus and host susceptibility.

Introduction The Newcastle disease virus in its velogenic form continues to be a serious problem in the poultry industry worldwide. Biosecurity and vaccination measures are the more effective control methods currently available. However, the antigenic and genetic diversity of the virus has put a phylogenetic distance of the current vaccine strains from the recent velogenic isolates found in Central and South America...

Laboratory testing shows that flies exposed to a food source infected with exotic Newcastle disease (END) can pick up the virus and carry it for several days, perhaps later passing it on to chickens that eat the food. “Flies can carry END virus and evidence is mounting that flies may be able to transmit the virus between chickens,” says Alec Gerry, UC Riverside assistant veterinary entomologist. END is a contagious and fatal viral disease affecting the respiratory,...

Avian influenza (AI) and Newcastle disease (ND) are poultry diseases of great concern to the poultry industry. The viruses that cause these diseases can be killed by heat. But the exact parameters for inactivating them by pasteurization had not been established—until now.
Agricultural Research Service (ARS) scientists have shown that the same industry-standard pasteurization temperatures and times established for Salmonella inactivation in egg products can also kill AI and ND viruses....
