First Report of Grapevine fleck virus in Idaho Grapevines

Elisa detection of grapevine fleck virus ( GFkV )

Résumé — Détection par Elisa du virus de la marbrure de la vigne (GFkV = grapevine fleck virus). L’association du Grapevine fleck virus (GFkV) avec les symptômes de la marbrure de la vigne a été établie par Elisa. La détection par Elisa du GFkV dans les plants de vigne n’est pas possible pendant la totalité du cycle végétatif : dans nos conditions, en Alsace, les mois de juin et juillet c...

Complete nucleotide sequence and genome organization of Grapevine fleck virus.

The complete nucleotide sequence of Grapevine fleck virus (GFkV) genomic RNA was determined. The genome is 7564 nt in size, excluding the 3'-terminal poly(A) tail, is characterized by an extremely high cytosine content (ca. 50%), and contains four putative open reading frames and untranslated regions of 291 and 35 nt at the 5' and 3' ends, respectively. ORF 1 potentially encodes a 215.4 kDa pol...

The emergence of Q1 genotype of avian infectious bronchitis virus in Iran, 2019: the first report

Background: Avian infectious bronchitis (IB) is an infectious viral disease of chickens. The effective protection of chickens against many different infectious bronchitis virus (IBV) variants is not achieved unless the circulating genotypes in the region are identified and the cross-protection of the potential of vaccines in use is assessed. Aims:In a monitoring program of IBVs, a new genotype ...

Emergence of Genotype VIIg of Velogenic Newcastle Disease Virus in Iran, 2018: The First Report

Newcastle disease virus (NDV) is a prototype member of avian paramyxovirus serotype 1 (APMV-1), which causes severe and contagious disease in the commercial poultry and wild birds. In this study, we report the results of phylogenetic analyses of recent NDVs isolated from Markazi province of Iran during a recent outbreak in the commercial broiler with respiratory signs and digestive system lesio...
