This study aimed to investigate rabbit hemorrhagic disease virus (RHDV) in China. VP60 sequences of five RHDVs collected by our team, as well as those of 16 other published Chinese RHDV strains, were analyzed. Polygenic analysis using MEGA 4 software showed that 20 of the 21 Chinese strains could be clustered in the RHDVa subgroup, and WX/China/1984 was(More)
BACKGROUND The rigorous evaluation of recombinant bovine adenovirus (BAdV)-3 as a gene delivery vector requires quick and efficient method of isolating recombinants. This requires both a suitable cell line and an efficient method of rescuing recombinant BAdV-3. To facilitate rapid isolation of recombinant BAdV-3, we have developed an efficient system for(More)
Nanobodies (or variable domain of the heavy chain of the heavy-chain antibodies, VHHs) are single-domain antigen-binding fragments derived from camelid heavy chain antibodies. Their comparatively small size, monomeric behavior, high stability, high solubility, and ability to bind epitopes inaccessible to conventional antibodies make them especially suitable(More)
The p13 gene is a group II nucleopolyhedroviruses (NPVs) specific gene and featured by containing upstream mini ORFs (uORF) in its 5' UTR region. However, there are almost no reports published on the functions of the uORFs of p13 gene. In this study, the Luciferase Reporter Assay System was employed to investigate how the mini ORFs of Helicoverpa armigera(More)
This study was conducted to evaluate the virulence and evolution of genotype IX Newcastle disease virus (NDV) isolates obtained from wild birds in the northern Qinling Mountains of China. Five isolates were obtained from 374 larynx and cloacae swabs, which were collected from multiple asymptomatic wild bird species from August 2008 to July 2011, and were(More)
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(More)
Wild birds are considered as a natural reservoir of Newcastle disease virus (NDV). However, there is no information about genotype IX NDV from wild birds, especially from Columbiformes. In this study, two genotype IX NDV viruses were isolated from wild birds. One was from Eurasian Blackbird, while the other was from Spotted-necked dove. After purification(More)
Avian encephalomyelitis virus (AEV) causes epidemic diseases in poultry worldwide. A SYBR Green real-time reverse transcription-polymerase chain reaction (rRT-PCR) assay was developed for the rapid detection and quantitation of AEV in this study. A pair of specific primers was designed in the highly conserved VP1 gene of this virus. When comparing this(More)
CREBZF, also known as Zhangfei or SMILE, is a member of the CREB/ATF protein family. CREBZF has mainly been considered as a basic region-leucine zipper transcription factor that functions in coordination with other transcription factors and plays a role in latent HSV-1 infection, apoptosis and the mammalian endoplasmic reticulum stress and unfolded protein(More)
Vaccine antigens for rabbit hemorrhagic disease virus (RHDV) are currently derived from inactivated RHDV obtained from the livers of experimentally infected rabbits or from several recombinant immunogens. However, the application of these vaccine antigens has been restricted because of biosecurity and immunity characteristics. In the current study, a(More)
