TWiV reviews an outbreak of Marburg hemorrhagic fever in Equatorial Guinea, wild poliovirus type 3 shedding from a laboratory in the Netherlands, and white-tailed deer as a reservoir for previous SARS-CoV-2 variants of concern.
The TWiVsters explain how the shape of pleomorphic virus particles – spherical or filamentous – determines the probability of virus attachment and fusion, and resistance to selective pressure such as antibodies that block cell entry.
The TWiVosophers review the Chinese plasma virome revealed by non-invasive prenatal testing, and a new filovirus genome from bats in China.
