BACKGROUND: Newcastle disease virus (NDV) is the causativeagent of the Newcastle disease (ND), a highly contagiousdisease in birds that causes significant economic losses to thepoultry industry worldwide. ND is endemic in Iran and outbreaksare reported regularly in commercial poultry flocks and differentspecies of birds. OBJECTIVES:The current study was carried outto characterize NDV based on p...

A paramyxovirus with a thermostability of 60 min (typical of velogenic viruses) and a mean death time of > 90 h (typical of lentogenic viruses) was isolated from layers near Mooi River, South Africa. Our results, based on comparative nucleotide sequence data indicated that the virus is pigeon paramyxovirus 1 (PPMV-1), a variant of Newcastle disease virus. The F0 cleavage site contains a 112RRKK...

The complete nucleotide sequence of the gene encoding the matrix protein (M) of the porcine paramyxovirus LPMV has been determined. The gene is 1376 nucleotides long including 5' and 3' non-coding sequences with a protein-coding sequence of 1107 nucleotides. The deduced protein, containing 369 amino acids with a calculated Mr of 41,657, is hydrophobic overall with a net positive charge of +17.5...

The effects of monospecific antibodies to the viral glycoprotein with hemagglutinating and neuraminidase activity (HN) and the viral glycoprotein with membrane-fusing activity (F) of the paramyxovirus simian virus 5 (SV5) on the spread of infection in two cell types have been investigated. In CV-1 cells, infection can spread by either released progeny virus adsorbing to and infecting other cell...

In public databases, we identified sequences reported as human genes expressed in kidney mesangial cells. The similarity of these genes to paramyxovirus matrix, fusion, and phosphoprotein genes suggests that they are derived from a novel paramyxovirus. These genes are sufficiently unique to suggest the existence of a novel paramyxovirus genus.

characterization of isolated pigeon paramyxovirus-1 (pmv-1) and its pathogenicity in broiler chickens were studied. two hundred and thirty-two samples collected from 50 unvaccinated pigeons lofts suspected to newcastle disease from private houses and bird markets from ahvaz , iran. swab samples from cloaca and oropharynx of live pigeons and from trachea, lung, liver, spleen, kidney, brain, prov...

Newcastle disease (ND) is one of the contagious viral diseases in avian species. Recently, several ND outbreaks in pigeon caused by pigeon paramyxovirus serotype-1 (PPMV-1) have been reported in limited numbers from Iran and phylogenetic studies have been conducted on partial sequence of NDV fusion (F) gene. In the present study, ten PPMV-1, named Pigeon_paramyxovirus1_isolate_pigeon/Iran/UT_EG...
