S. Ostrowski et al., ANTIBODY-RESPONSE TO NEWCASTLE-DISEASE VACCINATION IN A FLOCK OF YOUNG HOUBARA BUSTARDS (CHLAMYDOTIS-UNDULATA), Journal of zoo and wildlife medicine, 29(2), 1998, pp. 234-236
Twelve young houbara bustards (Chlamydotis undulata) were vaccinated w
ith a lentogenic strain of Newcastle disease virus. Another seven bird
s were kept in close contact with the treated flock but were not vacci
nated. Antibody levels were measured in all birds with hemagglutinatio
n inhibition test over the course of 1 yr. Antibody formation with no
side effects was observed in 18 birds. The duration and amplitude of t
he antibody response differed between the groups.
