RNA structure-altering mutations underlying positive selection on Spike protein reveal novel putative signatures to trace crossing host-species barriers in Betacoronavirus

, 2022
Similar to other RNA viruses, the emergence of Betacoronavirus relies on cross-species viral transmission, which requires careful health surveillance monitoring of protein-coding information as well as genome-wide analysis. Although the evolutionary jump

The effect of early-stage public health policies in the transmission of COVID-19 for South American countries

Revista Panamericana de Salud Pública, 2020
Objectives. The analysis of transmission dynamics is crucial to determine whether mitigation or suppression measures reduce the spread of coronavirus disease 2019 (COVID-19). This study sought to estimate the basic (R0) and time-varying (Rt) reproduction

Multi‐Layered Genomic and Clinical Analysis Identifies Novel Variants, Co‐Occurring Single Nucleotide Polymorphism Pairs, and Clinical Determinants of Host‐Pathogen Interaction in COVID‐19 Severity

Journal of Medical Virology, Volume 98, Issue 6, June 2026.
ABSTRACT Host genetic factors may contribute to COVID‐19 severity. To identify genetic variants influencing COVID‐19 severity progression, whole‐exome sequencing was performed, followed by an exome‐wide association study on 191 hospitalized patients categorized into three severity groups.

Isolation and characterization of a novel Betacoronavirus subgroup a coronavirus, rabbit coronavirus HKU14, from domestic rabbits

, 2012
We describe the isolation and characterization of a novel Betacoronavirus subgroup A coronavirus, rabbit coronavirus HKU14 (RbCoV HKU14), from domestic rabbits. The virus was detected in 11 (8.1%) of 136 rabbit fecal samples by reverse transcriptase PCR (

Serological evidence of a pararubulavirus and a betacoronavirus in the geographically isolated Christmas Island flying-fox (Pteropus natalis) [PDF]

, 2022
Due to their geographical isolation and small populations, insular bats may not be able to maintain acute immunizing viruses that rely on a large population for viral maintenance.

Targeting Middle East Respiratory Syndrome Coronavirus Spike Fusion Machinery With Antiviral Peptides: In Silico Exploration of the Heptad Repeat 2 Domain

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Griffithsin, Brevinin‐2, and CCL20 were identified as potent MERS‐CoV fusion inhibitor candidates targeting the HR2 domain through integrated molecular docking, MD simulations, and MM/PBSA analyses. These peptides demonstrated superior binding stability and favorable safety profiles compared to the standard inhibitor, supporting their potential as ...
