A sheep model to investigate the role of fungal biofilms in sinusitis: fungal and bacterial synergy

Abstract

Significant fungal biofilm only occurred when S. aureus was the co-inoculum. Hypersensitivity was not requisite. The relationship of S. aureus to fungal biofilms is of great clinical interest. Fungi may be opportunistic pathogens that simply require inflamed mucosa with weakened innate defenses; alternatively, a cross-kingdom synergy could be contributing to fungal proliferation.
