*Determined by agar diffusion tests according to European Committee on Antimicrobial Susceptibility Testing standards [24].
†Tests were done in 0.1M phosphate buffer at pH 7.1 and 37 °C; 1×106 c.f.u. ml−1 were incubated in test solutions and quantitative cultures were assessed after inactivation of the antiseptics with 1 % methionine/1 % histidine.
‡2 log10 reduction after 30 min.
