Virological characteristics of the SARS-CoV-2 Omicron XBB.1.5 variant

Date
Thursday, February 08, 2024 - 4:00 AM
Description
Circulation of SARS-CoV-2 Omicron XBB has resulted in the emergence of XBB.1.5, a new Variant of Interest. Our phylogenetic analysis suggests that XBB.1.5 evolved from XBB.1 by acquiring the S486P spike (S) mutation, subsequent to the acquisition of

An Update on COVID-19-Associated Placental Pathologies

Date
Thursday, February 08, 2024 - 4:00 AM
Description
COVID-19 pregnancies are associated with increased rates of premature delivery and stillbirths. It is still a matter of debate whether there is a COVID-19-associated pattern of placenta pathology. We updated our previously published results on a

Robust expansion of phylogeny for fast-growing genome sequence data

Date
Thursday, February 08, 2024 - 4:00 AM
Description
Massive sequencing of SARS-CoV-2 genomes has urged novel methods that employ existing phylogenies to add new samples efficiently instead of de novo inference. 'TIPars' was developed for such challenge integrating parsimony analysis with pre-computed
