Newcastle disease is a severe, systemic, and fatal viral disease of poultry due to virulent strains of avian paramyxovirus type 1. Clinical signs in unvaccinated birds include sudden death, lethargy, and respiratory distress. Diagnosis is based on laboratory confirmation. Vaccines prevent clinical signs but not infection, and the control of the disease is challenging in enzootic regions. Newcastle disease (ND) is an infection of domestic poultry and other bird species with virulent Newcastle disease virus (NDV). Newcastle disease is not a food safety or public health concern. Virulent NDV is capable of producing a devastating disease in domestic fowl, with vast social and economic consequences. It is a worldwide problem that presents primarily as an acute respiratory disease; however, depression, nervous signs, or diarrhea may be the predominant clinical form. Severity of ND depends on the virulence and genetic type of the infecting virus and host susceptibility.
Newcastle Disease, caused by Avian Paramyxovirus-1 (APMV-1), is a highly contagious viral disease affecting wild and domestic birds. Neurological and respiratory manifestations are most common, with viral strain and host species influencing susceptibility and virulence. Although clinical signs range from asymptomatic to lethal, APMV-1 is significant to the poultry industry as mortality may reach 100%. 1 Evaluation of potential reservoir hosts has focused on wild fowl (Galliform and...

WHY VACCINATE? Vaccination is an effective means to prevent and/or reduce the adverse effects of specific diseases in poultry. Poultry refers to birds that people keep for their use, and generally includes chicken, turkey, duck, goose, quail, pheasant, pigeon, guinea fowl, pea fowl, ostrich, emu and rhea. Disease-causing organisms can be classified, smallest to largest, as viruses, mycoplasma, bacteria, fungi, protozoa, and parasites....

Introduction Velogenic Newcastle Disease (ND), a dreadful poultry disease caused by a paramyxovirus type-I (Newcastle Disease Virus - NDV), continues to be an important threat to the modern poultry industry all over the world (4). An effective control of ND consists primarily of good biosecurity practices, preventive vaccination of flocks and the culling of infected birds and birds at risk of being infected. Vaccination...

Introduction
Viral respiratory diseases of significance are caused by only a handful of viruses represented by Newcastle disease virus (NDV), infectious bronchitis virus (IBV), infectious laryngotracheitis virus (ILTV), avian metapneumovirus (MPV), and avian influenza virus (AIV). Despite the relatively small number of types of viruses circulating in the field, the...
Introduction Fruits and vegetables, whole grains, beverages, and some fortified or omega-3 enriched products can be considered as functional foods. In fact, consumption of omega-3 is associated with reducing the risk of cardiovascular diseases, and cancers (Mozaffarian et al., 2005; Theodoratou et al., 2007) besides improving animal health and blood parameters (Jameel and Sahib, 2014). Tissue structure, muscles are the...
In my experience, during the rearing period of layer flock, most farmers faced problems with IBD and ND (resp.form/visceral form) at 20 to 30 days of age. Sometimes along with coccidiosis or colibacillosis. Mortality varies from 20 to 30%. Lost uniformity, less feed intake ,due to lake of knowledge, debeaking was done with less body weight. Lately, the flock performance was not satisfactory. Could veterinarians please help me with any...
Infectious diseases of poultry are mostly associated with severe economic losses. Many of these diseases once re-emerging or introduced into a geographic area can explode into an epidemic and may have a significant negative effect on international trade. Beside general control approaches like biosecurity, improvement of rearing management, monitoring, and vaccination several governmental measures on control of poultry diseases were adopted in European...

Vincristine is an effective therapy for the treatment of canine transmissible venereal tumor (CTVT); however, the time for a complete clinical remission may vary depending on the tumor stage and host status. The aim of this study was to investigate an alternative or adjuvant therapy usingNewcastledisease virus (NDV) for the treatment of CTVT that does not produce side effects and enhances the immune response against the tumor.

Newcastle disease (ND) is a highly contagious viral disease affecting wild and domestic avian species. It is a worldwide problem that presents primarily as a respiratory disease, but depression, nervous manifestations, or diarrhea may be the predominant clinical form. Mortality is variable. Occurrence of a virulent form of the disease is reportable and may result in trade restrictions. Also known as Exotic Newcastle Disease, Pseudo-Fowl Pest,...
