, a virulence factor that scavenges iron for bacterial growth, in clinical and nonclinical strains of P. aeruginosa. Manuka honey has also been shown to alter the structure of P. aeruginosa; scanning and transmission electron microscopy revealed changes in cell shape and cell lysis following incubation with honey. A honey flavonoid extract was also found to alter membrane integrity and branching processes associated with virulence in C.albicans.
