Feline coronavirus-infected domesticated cats found to possess cross-reactive anti-SARS-CoV-2 antibodies

In a recent study posted to the bioRxiv* preprint server, researchers confirmed that feline coronavirus (FCoV) infection induced the production of cross-reactive antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain (RBD) in domestic cats, despite minimal amino sequence acid (aa) similarity between RBDs of SARS-CoV-2, and FCoV serotype 1 (FCoV1) and serotype … Read more

Antibodies can prevent surface proteins of bacteria from entering host cells

Using bacteria of the Bartonella henselae species, researchers from Goethe University, Frankfurt University Hospital, the Paul Ehrlich Federal Institute for Vaccines and Biomedicines in Langen, and the University of Oslo demonstrated for the first time that antibodies can prevent certain surface proteins of bacterial pathogens from entering host cells. The findings are important for the … Read more

Investigating an effective linear deoxyribonucleic acid COVID-19 vaccine option for domestic cats

In a recent article posted to the bioRxiv* preprint server, investigators studied a linear deoxyribonucleic acid (linDNA) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine option in felines. Study: A linear DNA vaccine candidate encoding the SARS-CoV-2 Receptor Binding Domain elicits protective immunity in domestic cats.
