nucleotide and predicted amino acid sequence analysis of the fusion protein and hemagglutinin-neuraminidase protein genes among newcastle disease virus isolates. phylogenetic relationships among the paramyxovirinae based on attachment glycoprotein sequences.highly virulent newcastle disease virus (ndv) isolates are list a pathogens for commercial poultry, and reports of their isolation among member nations must be made to the office of international epizootes (oie). the virus is classified as a member of the order mononegavirales in the family paramyxoviridae of the subfamily paramyxovirinae. two interactive surface glycoproteins, the fusion (f) and hemagglutinin-neuraminidase (hn) proteins, play essential roles in ndv attachment and fusion of cell ...200415108051
characterization of velogenic newcastle disease viruses isolated from dead wild birds in serbia during 2007.avian paramyxoviruses type 1 or newcastle disease viruses (ndv) are frequently recovered from wild birds and such isolates are most frequently of low virulence. velogenic ndv are usually recovered from poultry and only occasionally from wild birds. five ndv isolates were obtained from carcasses of four wild bird species during 2007 in serbia: mallard (anas platyrhynchos), eurasian sparrowhawk (accipiter nisus), feral rock pigeon (columba livia), and eurasian collared dove (streptopelia decaocto) ...201121441197
expansion of an exotic species and concomitant disease outbreaks: pigeon paramyxovirus in free-ranging eurasian collared doves.eurasian collared doves (streptopelia decaocto) have expanded their range across the united states since their introduction several decades ago. recent mortality events in eurasian collared doves in arizona and montana, usa, during the winter of 2009-2010 were the result of pigeon paramyxovirus (ppmv), a novel disease agent. the first instance of mortality by this emerging infectious disease in this species occurred in florida in 2001 with subsequent disease events in 2006 and 2008. full diagnos ...201222476688
six-year surveillance of newcastle disease virus in wild birds in north-eastern spain (catalonia).given that newcastle disease (nd) is one of the major threats for the poultry industry, testing of newcastle disease virus (ndv) has been carried out since 2010 in cases of mortality in wild birds (passive surveillance) in catalonia. the objective is to provide an early warning system to prevent the infection of poultry. since 2010, 35 episodes of mortality in wild birds were attributed to ndv infection. throughout this period there was a progressive expansion of ndv to new areas, with an increa ...201727754702
natural infections with pigeon paramyxovirus serotype 1: pathologic changes in eurasian collared-doves ( streptopelia decaocto) and rock pigeons ( columba livia) in the united states.pigeon paramyxovirus serotype 1 (ppmv-1) is a globally distributed, virulent member of the avian paramyxovirus serotype 1 serogroup that causes mortality in columbiformes and poultry. following introduction into the united states in the mid-1980s, ppmv-1 rapidly spread causing numerous mortality events in eurasian collared-doves ( streptopelia decaocto) (ecdos) and rock pigeons ( columba livia) (ropis). the investigators reviewed pathological findings of 70 naturally infected, free-ranging colum ...201728382855
characterization of newcastle disease virus isolates obtained from eurasian collared doves (streptopelia decaocto) in italy.eurasian collared doves (streptopelia decaocto) are thought to originate from india and they have colonized, throughout the centuries, the middle east and, more recently, mediterranean countries such as italy and spain. in the present paper we report of the isolation and characterization of newcastle disease viruses (ndv) obtained from eurasian collared doves during 2000-2001, and compare them to isolates obtained from feral pigeons (columba livia) during the same period. all isolates could be c ...200312745382
