In pigeon Newcastle disease is caused by pigeon paramyxovirus type-1 (PPMV-1) which is a variant of avian paramyxovirus-1 (APMV-1) and characterized on the basis of monoclonal antibody-binding profiles. PPMV-1 in pigeons produces digestive and nervous disturbance and mortality and morbidity reaches up to 40 and 70 %, respectively. Submucosal to echymotic haemorrhages in proventriculus and intestine, tracheaitis, nephritis and encephalitis were observed in pigeons died PPMV-1 infection. The second most important disease found in pigeons, is coccidiosis which is well known among pigeon farmers with the common name of KHUNI PACHISH . Coccidiosis causes severe blood mixed diarrhea and enteritis . In coccidial infection, the immune system of bird becomes depressed and are more susceptible to bacterial and viral infections.
Newcastle disease (ND) is causing greater economic losses to the poultry industry worldwide due to high mortality, decreased productivity in affected birds, increased costs involving in controlling disease and other associated factors.Newcastle disease virus (NDV) is a RNA virus belonging to the genus avula virus, family paramyxoviridae. This disease affects various species of birds including chicken, ducks, pigeons, turkeys, Japanese quail, emus, crows, sparrows, wild birds etc. Free living birds infected with NDV excrete larger quantities of the virus in their excretions and secretions and act as a source of infection to domestic poultry. This book emphasis the role of free living birds in the transmission of ND to domestic poultry.
