Subgroup J avian leukosis virus (ALV-J), first isolated in 1989, predominantly causes myeloid leukosis (ML) in meat-type or egg-type chicken. Since 2006, the clinical cases of hemangioma rather than ML in commercial layer flocks associated with ALV-J have been reported, but it was still not clear whether the novel oncogenic ALV-J had emerged. We(More)
Foot-and-mouth disease virus (FMDV) is an important disease agent that can be difficult to effectively eradicate from herds. Because it is an obligate intracellular parasite, the virus has multiple effects on the host cell during infection. Here, a high-throughput quantitative proteomic approach was used to develop an unbiased holistic overview of the(More)
In our study, the pathogenicity of H5N1 influenza A viruses circulating in waterfowls in Southern China was investigated. Three H5N1 highly pathogenic avian influenza (HPAI) viruses isolated from ducks, A/Duck/Guangdong/383/2008(DK383), A/Duck/Guangdong/378/2008(DK378) and A/Duck/Guangdong/212/2004(DK212) were inoculated at 10(6) fifty-percent egg(More)
Infection of breeder flocks in China with subgroup J avian leukosis virus (ALV-J) has increased recently. In this study, we have developed a loop-mediated isothermal amplification (LAMP) assay for rapid detection of ALV-J from culture isolates and clinical samples. The ALV-J-specific LAMP assay efficiently amplified the target gene within 45 min at 63(More)
Severe acute respiratory syndrome (SARS) was caused by a novel virus now known as SARS coronavirus (SARS-CoV). The discovery of SARS-CoV-like viruses in masked palm civets (Paguma larvata) raises the possibility that civets play a role in SARS-CoV transmission. To test the susceptibility of civets to experimental infection by different SARS-CoV isolates, 10(More)
