Human ACE2 transgenic pigs are susceptible to SARS-CoV-2 and develop COVID-19-like disease by Long Fung Chau, Simon Lillico, Tanja Opriessnig, Rosemary Blake, Luc Tardy, Chen-Hsuin Lee, Scott Maxwell, Claire Warren, Elizabeth Thornton, Catherine L. Mclaughlin, Gerry McLachlan, Christine Tait-Burkard, Sarah Fletcher, Stephen Anderson, Sharon Brown, Louise Gibbard, Thomas Tzelos, Dawn MacMillan-Christensen, J. Kenneth Baillie, David A. Dorward, David J. Griffiths, Finn Grey

“…Abstract Animal models that accurately reflect COVID-19 are vital for understanding mechanisms of disease and advancing development of improved vaccines and therapeutics. Pigs are increasingly recognized as valuable models for human disease due to their genetic, anatomical, physiological, and immunological similarities to humans, and they present a more ethically viable alternative to non-human primates. …”

Research note: Establishment of a multiplex PCR detection system for different infectious bronchitis virus strain genotypes in laying hens by Changjing Zhao, Cheng Yuan, Qingsen Zhao, Aihong Xia, Yaqing Dong, Shuying Xu, Shihan Chen, Yue Yuan, Yongjuan Wang

“…This study produced a method for the fast detection and identification of five strains of infectious bronchitis virus (IBV), including the currently prevalent wild-type QX and G Ⅵ-1 strains, in addition to the Mass, 4/91, and LDT3 strains that are used as vaccines. Based on the spike 1 (S1) glycoprotein gene sequences of the IBV Mass, QX, G Ⅵ-1, 4/91, and LDT3 strains, five sets of customized primers, showing excellent specificity, were designed and synthesized to target the appropriate conserved sequences. …”

Ezebuo, InnocentMary Ejiofor, Mercy Adebola, Innocent Okpoli, Beatrice Cubitt, Haydar Witwit, Chetachi B. Okwuanaso, Ngozi Onyemelukwe, Juan Carlos de la Torre

“…Lassa fever (LF), a viral hemorrhagic fever disease with a case fatality rate that can be over 20% among hospitalized LF patients, is endemic to many West African countries. Currently, no vaccines or therapies are specifically licensed to prevent or treat LF, hence the significance of developing therapeutics against the mammarenavirus Lassa virus (LASV), the causative agent of LF. …”
