Robust vaccines are required to protect village chickens against Newcastle disease. Thermostable vaccines derived from avirulent Australian strains of Newcastle disease virus (strains V4 and I-2) have proved successful for this purpose. These vaccines have been developed through ACIAR projects and have been adopted by other international aid agencies. It is now possible to offer integrated work...

Newcastle disease (ND) is a highly contagious disease that affects many species of birds and causes significant economic losses to the poultry industry worldwide and the pathogenicity of Newcastle disease virus (NDV) strains varies with different virulence. Samples were collected from chicken commercial farms in Iran during 2014–2015. ND virus were characterized (NDV) by partial sequences...

This study was designed with the goal of adding as much information as possible about the role of pigeons (Columba livia) and chickens (Gallus gallus) in Newcastle disease virus epidemiology. These species were submitted to direct experimental infection with Newcastle disease virus to evaluate interspecies transmission and virus-host relationships. The results obtained in four experimental mode...

background and aims: the objective of this study was to investigate the effects of newcastle disease and infectious bronchitis vaccination programs in chickens. materials and methods and results: in the present study, 225 day-old broiler chicks divided into 5 groups. the groups were submitted to vaccinations, except for the non-vaccinated control group. the chickens in the groups 1 were kept as...

Newcastle disease causes many economic losses to the poultry industry in most countries. This disease is endemic in Iran. Backyard poultry is considered the reservoir of Newcastle virus; however, there is either no vaccination program against Newcastle, or it is performed in a restricted manner. Commercial live vaccines are inactive and sensitive to temperature; moreover, vaccine delivery to vi...

Received: Revised: Accepted: June 01, 2014 August 19, 2014 August 28, 2014 Newcastle disease (ND) is one of the most important diseases of avian species across the world. The present study was conducted to investigate the carrier potential of four common wild birds towards ND virus. Indian mynah (n=25), house sparrow (n=25), house crow (n=25) and pigeons (n=25) were captured using mist netting ...
