A TWiV trio reveal the isolation of novel paramyxoviruses from rodents and bats in Arizona, and isolation of naive B cells from seronegative donors that produce germline encoded antibodies which engage the receptor binding domain of SARS-CoV-2, variants of concern, and related sarbecoviruses from bats.
From the TWiV team, human cowpox infection possibly acquired from a pet cat, and a new giant mimivirus of green algae with genes encoding enzymes of fermentation.
