Emerging viral diseases [PDF]

Proceedings of the National Academy of Sciences, 2000
We live in an era of rapidly changing global landscapes and local environments. Viruses with RNA as their genetic material can quickly adapt to and exploit these varying conditions because of the high error rates of the virus enzymes (polymerases) that replicate their genomes.

Phylogenetic analysis of the viral proteins VP4/VP7 of circulating human rotavirus strains in China from 2016 to 2019 and comparison of their antigenic epitopes with those of vaccine strains

Frontiers in Cellular and Infection Microbiology, 2022
Group A rotaviruses (RVAs) are the most common etiological agents of severe acute diarrhea among children under 5 years old worldwide. At present, two live-attenuated RVA vaccines, LLR (G10P[15]) and RotaTeq (G1–G4, G6 P[8], P[5]), have been introduced ...

Non-replicating Vaccinia Virus TianTan Strain (NTV) Translation Arrest of Viral Late Protein Synthesis Associated With Anti-viral Host Factor SAMD9

Frontiers in Cellular and Infection Microbiology, 2020
NTV is a highly attenuated virus that was created by genetically deleting 26 genes related to host range and virulence from TianTan strain. Since NTV is highly attenuated, it has been used widely as an optimizing viral vector.
