Bacteria often show very strong biogeography—some bacteria are abundant in specific locations while absent from others—leading to major questions when applying microbiology to therapeutics or probiotics: how did the bacteria […]

COVID-19 infects the mouth. Could that explain patients’ taste loss?

The coronavirus SARS-CoV-2 can infect cells in the mouth, which may spur the virus’s spread both in the body and to other people, according to a preliminary study. In the new study, posted Oct. 27 to the preprint database medRxiv, researchers predicted which mouth tissues might be most vulnerable to SARS-CoV-2, the virus that causes […]
