SARS-CoV-2 may infect bacteria in the gut, act as a bacteriophage

“SARS-CoV-2 could .. infect bacteria in the gut microbiota, indicating that SARS-CoV-2 could act as a bacteriophage

“Our recent studies show that microorganisms in the human gastrointestinal tract affect the severity of COVID-19 and for the first time provide indications that the virus might replicate in gut bacteria....More...

Preprint: Intranasal delivery of SARS-CoV-2 Spike protein is sufficient to cause olfactory damage

We hypothesize that SARS-CoV-2 spike (S) protein is sufficient to cause olfactory damage and olfactory dysfunction.

Using an adult zebrafish model, we report that intranasally delivered SARS-CoV-2 S RBD mostly binds to the non-sensory epithelium of the olfactory organ and causes severe olfactory histopathology characterized by loss of cilia, hemorrhages and edema....More...

Preprint: SARS-CoV-2 Omicron – multiple inter-variant recombination events

“By analyzing sequences from a large number of Omicron subvariants, we identified diverse recombination events between two Omicron subvariants and several SARS-CoV-2 variants, suggesting that co-infection and subsequent genome recombination play important roles in the on-going evolution of SARS-CoV-2....More...
