“…Wildlife animal species serve as long-term reservoirs of infection, but the delicate acquired balance between trypanotolerance and trypanosome challenge can be disrupted by an increase in challenge and/or the introduction of new more virulent species into the ecosystem. There is a need to protect wildlife, animal, and human populations from the infectious consequences of encroachment to preserve and protect these populations. …”

The immunogenicity of PRV ΔgE/TK/UL49.5 three-gene-deleted vaccine in mice by Chenmeng Ding, Yawei Sun, Xianfeng Zhang, Mengmeng Shi, Han Yang, Xin Zhou, Shuangshuang Li, Yongtao Li, Xia Yang, Linyang Yu, Lu Chen

“…Immunized mice could induce high levels of serum neutralization antibodies and immune cytokines, including IFN-γ and IL-4, which could provide complete protection against virulent PRV challenge. No obvious pathological damage was observed in lung, brain and trigeminal ganglion of mice immunized with PRV ΔgE/TK/UL49.5, and the tissue viral load was the lowest. …”

A novel high-throughput screen identifies phenazine-1-carboxylic acid as an inhibitor of African swine fever virus replication in primary porcine alveolar macrophages by Jing Lan, Rui Luo, Di Liu, Changxing Qi, Xin Song, Zhanhao Lu, Ruojia Huang, Yuying Yang, Yuan Sun, Yonghui Zhang, Tao Wang, Hua-Ji Qiu

“…To conduct high-throughput screening (HTS) for anti-ASFV drugs, we initially developed a recombinant dual-reporter virus (rASFV-Gluc/EGFP) using the virulent strain ASFV HLJ/18 (ASFV-WT). The enhanced green fluorescent protein (EGFP)- and Gaussia luciferase (Gluc)-encoding genes were incorporated downstream of the ASFV MGF300-4L gene without disrupting viral genes. …”
