Vaccination against newcastle disease [PDF]
Tropical Animal Health and Production, 1982 Two field trials carried out on 2,000 broiler chickens showed that chickens vaccinated with the lyophilised Newcastle disease (ND) "F" vaccine at 1, 21, and 42 days were protected when challenged at 14, 35, 56 and 70 days with the virulent strain of Newcastle disease virus (NDV) administered intramuscularly, intranasally, or by contact.

Case Report: Newcastle Disease in Paraguay
Avian Diseases, 1972A serious outbreak of a velogenic strain of Newcastle disease occurred in Paraguay in August, 1970. Deaths of domestic poultry were very high in affected flocks. Vaccination against Newcastle disease had been prevented by law. This was rescinded, however, and voluntary vaccination was started.

Since 1926, there have been three epizootics of ND. The latter two have been directly linked with psittacine species and Racing Pigeons. The modern poultry industry is extremely vulnerable to the effects of NDV, once it gains entry to any facet of the industry. Consequently considerable expense and effort are expended to keep the virus at bay. The main

Journal of Wildlife Diseases, 1979
Between March and October, 1975, 37 captive lanners (Falcon biarmicus abyssinicus) destined for exportation to Europe from Kano, Nigeria were examined for Newcastle Disease (ND) by the haemagglutination-inhibition technique in our laboratory. Twenty-one or 57% of the falcons showed high titres, presumably as the result of natural exposure to ND virus.

Epizootiology of Newcastle Disease in Waterfowl
Avian Diseases, 1975Antibodies to Newcastle disease virus (NDV) as measured by hemagglutination-inhibition and virus-neutralization tests were detected in 40/236 Canada geese captured while in their southward migration or in their wintering grounds. Antibodies were also found in 37/267 wild ducks and in 20/31 domestic geese.

1. In this paper several historical and contemporary aspects of Newcastle disease (ND) are reviewed, with particular reference to the greater understanding which modern techniques have allowed. 2. Virulent ND viruses were generally thought to have emerged in 1926 as a result of transfer from a wild bird host reservoir but there is evidence that the ...
