Newcastle disease is a highly contagious, generalised viral disease of domestic poultry, cage and aviary birds, and wild birds. Clinical history of Newcastle disease could include sudden change in health, production and mortality. Clinical signs of virulent Newcastle disease in affected poultry include severe depression, sudden drop in egg production, respiratory disease, nervous signs such as paralysis, torticollis, tremors of the head and unsteady gait, diarrhoea, and rapidly escalating and continuing deaths. The recent Australian cases were predominantly characterised by nervous signs and/or respiratory disease.
Low pathogenicity strains of Newcastle disease have been circulating in Australian wild birds and poultry since at least 1960s. Initially, these were not associated with any clinical disease. The significant outbreaks of Newcastle disease in chickens in late 1990s/ early 2000s were due to locally derived strains that had become pathogenic; these were distinct viruses from those present in wild birds.
Vaccination of commercial poultry is compulsory in NSW. Either killed vaccine, or live avirulent V4 strain in which case some birds will remain carriers.
Differential diagnoses include acute fowl cholera, respiratory disease complex and other exotic diseases such as avian influenza.
Pigeon paramyxovirus is closely related to, but different from, Newcastle disease.
A diagnosis of virulent Newcastle disease is suggested by high mortality in poultry with confirmation by real-time PCR.

Commercial couriers may use either road or air transport and specimens should therefore be packed in accordance with International Air Transport Association (IATA) requirements. Most submission sent by veterinarians to the SVDL for testing are defined as “Biological Substance Category B” and must be packed according to the IATA packing instructions 650 (Biological Substance Category B). As requirements for transport can change, customers should consult with their transport agent to obtain current requirements.
Samples may also be hand delivered to the site during normal business hours (8.30am - 4.30pm).
