The paper sequences Betacoronavirus gravedinis from white-footed mice in NYC, identifies positively selected sites in the spike protein, and predicts its geographic distribution using phylogenetic and biodiversity data.

The paper identifies a deletion in domain 0 of the spike gene in highly pathogenic feline coronavirus type 2 from U.S. cats, suggesting it as a biomarker for pathogenicity.

This paper develops a hybrid capture sequencing platform for tick-borne disease detection, identifying emerging pathogens and ecological transmission networks in New York.

This study shows that a deletion in the NSP1 protein of SARS-CoV-2 variants reduces virulence by impairing host translation shutoff, suggesting NSP1 as a target for antiviral strategies.

This study reports an outbreak of canine coronavirus type 2 in snow leopards, suggesting felids may act as mixing vessels for alphacoronaviruses.

The study surveys white-footed mice in Connecticut, finding low SARS-CoV-2 seroprevalence and identifying two divergent betacoronaviruses.

The paper tracks intra-host variation in the spike S1/S2 region of FCoV-1 in a cat over six years, showing distinct variants in different tissues and shedding patterns.
