| phylogenetic and pathogenic analyses of two virulent newcastle disease viruses isolated from crested ibis (nipponia nippon) in china. | the crested ibis is one of the most endangered birds in the world, found only in shaanxi province in central china, and it has been reintroduced in sadogashima in japan. two newcastle disease virus (ndv) isolates were collected from sick crested ibises, and their pathogenic and phylogenetic characteristics were investigated. the results showed that they are virulent, with intracerebral pathogenicity indices of 1.46-1.83 and a mean time of death of 54.4-84.4 h. they shared the same virulent motif ... | 2013 | 23344613 |
| genomic characterisation of two virulent newcastle disease viruses isolated from crested ibis (nipponia nippon) in china. | this paper describes the complete genomic sequences of two virulent newcastle disease virus (ndv) isolates, shaanxi06 (prevalent genotype viid) and shaanxi10 (novel sub-genotype vii), from sick crested ibises. the genomes of both isolates were 15,192 nt long and consisted of six genes in the order of 3'-np-p-m-f-hn-l-5'. the genomes of the two isolates were highly similar to other reference ndv strains. however, some unique features were found in the hn protein of shaanxi06 and the f gene end of ... | 2014 | 25281014 |
