To explore adaptation of avian influenza virus to mice we previously performed serial lung-to-lung passages of the influenza A/Chicken/Jiangsu/7/2002 (H9N2) strain, resulting in the isolation of a variant influenza strain lethal for mice. We now report that virulence correlates with improved growth characteristics on mammalian cells and extended tissue… (More)
Thermostable Newcastle disease virus (NDV) vaccines have been used widely to protect village chickens against Newcastle disease, due to their decreased dependence on cold chain for transport and storage. However, the genetic basis underlying the NDV thermostability is poorly understood. In this study, we generated chimeric viruses by exchanging viral genes… (More)
The aim of this study was to develop a one-step real-time reverse transcription-polymerase chain reaction assay using the minor groove binding probe (MGB rRT-PCR) for rapid and quantitative detection of classical swine fever virus (CSFV). The method, which targets the 5′-nontranslated region (5′NTR) of the viral genome, detected all CSFV isolate tested, but… (More)
To evaluate the effects of the Toll/interleukin-1 receptor domain-containing adaptor-inducing interferon-beta (TRIF) on immune responses induced by DNA vaccines, mice were immunized with the eukaryotic expression plasmid pcDNA/E2 encoding classical swine fever virus (CSFV) E2 alone or in combination with the TRIF genetic adjuvant. Immune responses were… (More)
Transgenesis for Strongyloides and Parastrongyloides was accomplished in 2006 and is based on techniques derived for Caenorhabditis elegans over two decades earlier. Adaptation of these techniques has been possible because Strongyloides and related parasite genera carry out at least one generation of free-living development, with adult males and females… (More)
Thermostable Newcastle disease virus (NDV) vaccines have been used widely to control Newcastle disease for village poultry flocks, due to their independence of cold chains for delivery and storage. To explore the potential use of thermostable NDV as a vaccine vector, an infectious clone of thermostable avirulent NDV strain TS09-C was developed using reverse… (More)
A thermostable avirulent Newcastle disease virus (NDV) strain TS09-C was developed by serial passage of V4 strain in BHK-21 cells. The complete genome sequence of strain TS09-C was determined and compared with the sequences of other NDV isolates representing different thermostable phenotypes. The TS09-C genome was 15,186 nucleotides long and consisted of… (More)
We report here the complete genome sequence of virulent fowl adenovirus serotype 4 strain HB1510, isolated from a diseased chicken with hydropericardium-hepatitis syndrome in Hubei, China, in 2015. The viral genome is 43,721 bp long, and sequence analysis showed an 11-amino-acid deletion in open reading frame 29 (ORF29).
Riemerella anatipestifer is an important bacterial pathogen associated with epizootic infections in waterfowl and various other birds. Riemerella anatipestifer strain RA-JLLY is an avirulent strain, isolated from the brain of an old duck in Hubei province, China. Here, we report the genome sequence of this species.
In-ovo vaccination is an attractive immunization approach for poultry industry. However, most of the Newcastle disease virus (NDV) vaccine strains used after hatch are unsafe, as in-ovo vaccines, due to their high pathogenicity for chicken embryos. In this study, we evaluated the safety and immunogenicity of a thermostable NDV strain TS09-C, derived from V4… (More)
