Here, we report the complete genome sequences of two Newcastle disease virus (NDV) isolates, Adygea/duck/12/2008, from a wild duck in Russia, and Altai/pigeon/777/2010, from a pigeon in Russia. Based on comparative sequence analysis of the F gene, these strains were classified as NDV class II, genotypes VIId and VIb/2, respectively.

In this study, we report the complete genome sequence of a novel Newcastle disease virus (NDV) strain, Sheldrake duck/China/Guizhou/SS1/2014, isolated from Sansui Sheldrake duck flocks in Guizhou Province, southwestern China. The genome of this isolate is 15,192 nucleotides in length, which belongs to NDV genotype VIId in class II. This discovery will help us further study the epidemiology char...

A novel synthesis of 2-hydroxy-N'-(2-oxoindolin-3-ylidene) benzohydrazide derivatives was synthesized by the condensation of 2-hydroxybenzohydrazide with substituted isatins. The synthesized compounds were characterized by FT-IR, (1)H-NMR, and mass spectral data. Further, the compounds were screened for in vivo anti-inflammatory activity by carrageenan induced paw edema method. The tested compo...

We report here the complete genome sequence and biological characterization of a virulent Newcastle disease virus (NDV) strain, NDV/duck/Jiangsu/JSD0812/2008, isolated from laying ducks in Jiangsu Province, China. The genome is 15,192 nucleotides in length and is classified in subgenotype VIId of genotype VII, class II.

In 2000, three Newcastle disease virus (NDV) strains were isolated from outbreaks of infection in layers, ducklings, and geese in the same region of China during the same time period. Here, we report their complete genome sequences, which belong to the NDV genotype VIId. This discovery might provide clues as to the evolution of the NDVs of different avian origins.

Fifty-six Newcastle disease virus strains collected from 2000 to 2006 could be grouped into subgenotype VIId. However, they displayed cumulative mutations in and around the linear epitope of hemagglutinin-neuraminidase (residues 345 to 353) with time. The antigenicities of the variants that became predominant in Korea differ from each other and from the wild type.

Isolates of Newcastle disease virus (NDV) from chicken cases were obtained from various locations in Taiwan during 2003-2006 and were genotypically analyzed by using reverse transcription polymerase chain reaction (RT-PCR) with primers specific to the viral fusion (F) protein gene (534 bp). Part of the amplified F protein DNA product (nucleotide sequence 47-418) and the deduced amino acid seque...

Newcastle disease (ND) causes severe economic losses in poultry production. Despite the intensive vaccination regimes of NDV in Egypt, many outbreaks are being reported. The present study focused on the preparation and evaluation of inactivated velogenic Newcastle disease virus vaccine (genotype VII) isolated from Egyptian broiler chicken during 2015-2016. Fifty-five tissue samples including tr...

Thirty Newcastle disease virus (NDV) strains isolated from outbreaks in China during 1996 to 2005 were characterized pathotypically and genotypically. All strains except one were velogenic. An analysis of the variable region (nucleotides 47 to 420) of the F gene indicated that 6 isolates belonged to genotype II, 3 to genotype III, 1 (isolated from a pigeon) to genotype VI, and 20 to genotype VI...
