Three individual peptide sequences, EVSHPKVG, WVTTSNQW, and SGGSNRSP, which have potentials to bind to Newcastle disease virus (NDV), were identified by the biopanning method using phage display technology. The binding specificities of these peptides presented on phages were confirmed by ELISA competition assay using chicken anti-NDV antiserum. The synthetic peptides designed based on these res...

A procedure has been developed for the determination of the concentration of infective Newcastle disease virus (NDV) based on the enumeration of singly infected and distributed HeLa cells which are visualized by staining with fluorescent antibody. Infective virus assayed by the fluorescent cell-counting procedure is expressed in terms of cell-infecting units (CIU). Adsorption of NDV to HeLa cel...

Newcastle disease virus [NDV (avian paramyxovirus type 1 [APMV1])] isolates were recovered from imported exotic birds confiscated following importation into the United States, from waterbirds in the United States, and from poultry. The exotic birds probably originated from Central and South America, Asia, and Africa. The NDV isolates were initially characterized as highly virulent because of a ...

Complementary DNA clones to 90% of the Newcastle disease virus (NDV) genome have been produced and mapped. These clones cover the entire HN, F and M genes, most if not all of the L gene and parts of the NP and P genes. The map of overlapping clones gives the gene order 3'-NP-P-M-F-HN-L-5' for NDV, identical to the gene order of Sendai virus, on the assumption that the NP gene of NDV is at the 3...

Blood, Vol. 52, No. 1 (July). 1978 47 Thrombocytopenia may occur in association with some viral infections. The objective of the present study was to examine the mechanisms by which myxoviruses may induce thrombocytopenia via a direct effect on platelets. Newcastle disease virus (NDV) caused platelet aggregation and loss of granule and cytoplasmic constituents from washed rabbit platelet suspen...

Infectious bursal disease virus (IBDV) causes a highly immunosuppressive disease in chickens. Currently available, live IBDV vaccines can lead to generation of variant viruses. We have developed an alternative vaccine that will not create variant IBDV. By using the reverse genetics approach, we devised a recombinant Newcastle disease virus (NDV) vector from a commonly used vaccine strain LaSota...

One thousand six hundred day old poults were randomly divided into four pens of 400 each. Twenty-five percent the birds in 3 and 4 inoculated orally, with Eschericia coli (E. coli) 0111ab. Ten pen 2 inoculated, intratracheally 10°EIDso Newcastle disease virus (NDV), A1.315/12 10 (previously exposed to E. 0111ab) also NDV. A total 19 0111ab recoveries, was made out 200 that 4. Sampling liver sup...

UNLABELLED It has been reported that lentogenic Newcastle disease virus (NDV) isolates have the potential to become velogenic after their transmission and circulation in chickens, but the underlying mechanism is unclear. In this study, a highly velogenic NDV variant, JS10-A10, was generated from the duck-origin lentogenic isolate JS10 through 10 consecutive passages in chicken air sacs. The vel...

Newcastle disease virus (NDV), an avian paramyxovirus, is tumor selective and intrinsically oncolytic because of its potent ability to induce apoptosis. Several studies have demonstrated that NDV is selectively cytotoxic to tumor cells but not normal cells due to defects in the interferon (IFN) antiviral responses of tumor cells. Many naturally occurring strains of NDV have an intact IFN-antago...

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...
