Methods
S. aureus strains isolated from non-CRS controls (n=5), CRSsNP
(n=4) and CRSwNP patients (n=4) were sequenced using short read paired
sequencing and interrogated for carriage of virulence genes. A
representative control and CRSwNP isolate were tested for intracellular
survival in the LAD2 mast cell line to investigate phenotypic
differences.
