This study examines the molecular effects of Omicron spike mutations on ACE2 binding and antibody escape, revealing compensatory stabilizing mutations that enable high mutation counts.

The paper shows SARS-CoV-2 Omicron variant infects white-tailed deer on Staten Island, with age-dependent antibody prevalence and evidence of human-to-deer spillover.

SARS-CoV-2 was detected in one-third of sampled white-tailed deer in Iowa between September 2020 and January of 2021 that likely resulted from multiple human-to-deer spillover and deer-to-deer transmission events.

The study evaluates anti-SARS-CoV-2 antibody and neutralizing titer profiles in convalescent plasma samples to determine the optimal donation window for immunotherapy.

This study finds a strong correlation between anti-RBD and anti-ECD IgG titers and in vitro virus neutralization titers in convalescent plasma, suggesting these titers can serve as surrogates for neutralizing activity.

The paper examines genetic variation in the Spy1336/R28 and Spy1337 virulence genes of S. pyogenes and its effects on transcript levels and virulence in infection models.

The paper discovers a new Klebsiella species, K. quasivariicola, through whole genome sequencing of a clinical isolate phylogenetically distinct from known species.
