Diversity (a), clustering (b), and taxa abundances (c) of nasopharynx bacterial communities from SARS-CoV-2 positive or negative patients, respectively. In (a) indexes to measure the diversity within samples are shown, in (b) dissimilarity between samples is calculated as the Bray-Curtis or the Jaccard distance, and in (c) taxa represent 20 relatively most abundant genera within the five phyla that compose the nasopharynx bacterial community
