BookPublisher: 1984Subject(s): Department of MicrobiologyDDC classification: 0190,T Dissertation note: Three species of birds i.e. doves, parrots and quails, 100 from each species were studied to investigate their role in the epizootiology of Newcastle disease. The serum of each bird was examined for the presence of antibodies to Newcastle disease virus by Haemagglutination Inhibition method using a standard Newcastle disease virus obtained from Veterinary & Research Institute, Lahore. It was observed that 46% of parrots, 29% of doves and 7% of quails had experienced Newcastle disease. The average titre for three species of birds was 76 with a range of 20-1280, being highest in parrots and lowest in quails. Attempts were made to isolate Newcastle disease virus from the faecal material and pooled organs of each bird in developing chick embryo. Five isolates of Newcastle disease virus were recovered from parrots, two from doves and none from quails. The recovered isolates possessed a mild to moderate pathogenicity for day old chicks. From these trials it was evident that doves and parrot could act as carriers of Newcastle disease and disseminate the disease to other birds over vast areas while despite their susceptibility the exact role of quails could not be determined in the epizootio- logy of Newcastle disease. Further studies on larger scale were recommended.
