Imaging Staphylococcus aureus biofilms in vivo reveals neutrophil exclusion by PNAG exopolysaccharide
ABSTRACT Staphylococcus aureus forms biofilms on biotic and abiotic surfaces, enabling persistent infections that evade immune clearance. Although many S. aureus strains can produce the biofilm-associated exopolysaccharide, poly-β-1,6-N-acetyl-D-glucosamine (PNAG), they often form protein-dominated biofilm matrices in...
