Log reduction of microbial cells in the antimicrobial tests^*

Contact time (min)	S. aureus	E. coli	MRSA	VRE	C. albicans
5	1-log	2-log	1-log	1-log	1-log
10	2-log	3-log	3-log	3-log	2-log
30	3-log	4-log^**	4-log	4-log	3-log
60	4-log				4-log

S. aureus, E. coli, MRSA, VRE, and C. albicans concentrations were 10⁸–10⁹ CFU/mL, and 10 µL of such microbial suspension was used in each test (see text for details); the chlorinated PU-HDI-DMH surface contained (1.76 ± 0.11) × 10¹⁶ atoms / cm² of active chlorine.
