Fig 2.

Phylogenetic tree depicts relationships among isolates with branches labeled by isolate IDs. Rings represent source, PCR status, mec type, and MLST types. Bar graphs plot agr type frequency and disruptive agr variant presence by PCR status.

Phylogenetic analysis of S. aureus isolates. (a) The first isolate for each patient in the biorepository is included. Reference strains are labeled. Concentric circles represent CC/ST, mec type (only types II and IV were represented in this collection of isolates; if no mec type is indicated, the strain is mec negative), SARS-CoV-2 PCR result, and isolate source. (b) agr type and (c) agr mutations analyzed by SARS-CoV-2 PCR result. A disruptive agr variant was defined as a frameshift or stop gain. ** = reference strain CA-347. CC = clonal complex, ST = sequence type, “NA” = other or not categorized.
