Characterization of the Oropharyngeal Microbiomes in COVID-19 Omicron Variety Infection and Recovery Patients

To characterize the oropharyngeal microbiota in patients with SARS-CoV-2 Omicron variety and recovered patients; evaluate the potential of microbiome as non-invasive biomarkers for Omicron variety. Exploration of oropharyngeal microbiomes between different strains.We collected oropharyngeal swabs from 297 confirmed cases of COVID-19 Omicron variant (CCO), 222 confirmed case of Omicron who recovered (CCOR), 73 confirmed cases of original strain (CCOS) and 199 healthy controls (HC), then completed Miseq sequencing.
