Surface bioburden expressed as mean cfu per ampoule or vial in 10 hospital pharmacies after one-step LP disinfection and in an experimental setting after one-step TT disinfection

	Plastic ampoules		Glass ampoules		Injection vials		All kinds of containers
	Mean cfu*	SD	Mean cfu*	SD	Mean cfu*	SD	Mean cfu*	SD
one-step LP	0.36 (n=100)	1.15	0.50 (n=90)	0.94	0.29 (n=100)	1.07	0.38 (n=290)	1.06
one-step TT	0.03 (n=30)	0.18	0.20 (n=30)	0.41	0.13 (n=30)	0.43	0.12 (n=90)	0.36
p	0.029		0.073		0.241		0.002

*cfu determined by contact plate.
cfu, colony-forming unit; n, number of samples examined; p, p value; one-step LP is reference group.
