We report here the complete genome sequence of a Newcastle disease virus (NDV) isolate, NDV/Altai/pigeon/770/2011, isolated from a rock dove in the Russian Federation. On the basis of phylogenetic analysis, this strain was clustered into genotype VIb class II.

Newcastle disease is characterized by respiratory manifestations in association with nervous and/or digestive symptoms. Its prevention is done by vaccination with live attenuated (lentogenic strains) and/or killed vaccines. The lentogenic strains can lead to strong post-vaccination reaction, principally due to the presence of other pathogenic agents. Among them, Mycoplasma synoviae is worldwide...

Newcastle disease (ND) is a major threat to poultry industry production throughout developing countries. The Newcastle disease viruses (NDVs) infecting industrialized and indigenous poultry in Iran are velogenic strains and responsible for the frequent outbreaks of ND in poultry farms even in vaccinated flocks causing serious economic losses in the commercial and indigenous poultry. However, va...

Three strains of Mycoplasma arthritidis were shown to induce marked hyporeactivity in mice to interferon induction by both Newcastle disease virus and poly(I:C). In contrast, the interferon response of mice to tilorone was only partially suppressed by pretreatment of the animals with mycoplasms. Hyporeactivity to Newcastle disease virus was maximal 1 and 3 days after mycoplasms treatment, but t...

background and aims: newcastle disease virus (ndv) is one of the major pathogen in poultry. vaccination is intended to control the disease as an effective solution nevertheless this virus is a growing threat to the poultry industry. f gene open reading frame (orf) from ndv is 1650 bp, encoding a protein of 553 amino acids that can induce protective immunity alone. the f glycoprotein on the surf...

Avian influenza viruses of the H5 and H7 hemagglutinin subtypes, and Newcastle disease virus (NDV), are important pathogens in poultry worldwide. Specifically, the highly pathogenic H5N1 avian influenza virus is a particular threat because it has now occurred in more than 40 countries on several continents. Inasmuch as most chickens worldwide are vaccinated with a live NDV vaccine, we embarked ...

to evaluate the effect of supplemental vitamin c (vc) levels on performance and immune response of broiler chicks, 300 day-old ross male broiler chicks were allocated to a completly randomized design of 5 treatments(500 and 1000 ppm in diet, 500 and 1000 ppm in drinking water and control). immunity was assessed as antibody production against infectious bronchitis virus (ibv) and newcastle disea...

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...
