Abstract
A survey was conducted to study clinical signs, gross and histopathological
lesions in pigeons with naturally occurring Newcastle
disease. For this purpose, 30 pigeon lofts were visited. Among these, 14 lofts
showed clinical signs of Newcastle
disease, including mainly greenish white mucoid diarrhoea and nervous signs with
high morbidity and mortality. Postmortem examination of affected birds showed
lesions mainly in brain, liver, kidneys and spleen. Amongst various organs,
kidneys were more frequently involved. Histopathological changes were also
observed in lungs, liver, kidneys, brain and spleen. The results showed that the
Newcastle disease virus was widespread in pigeons locally
and caused heavy mortality. No preventive measures or vaccination is being
adopted by pigeon fanciers to control the disease.
