Sensitivity of H. pylori to rhLYS.

Time (h)	Cell Survival
	0.3 mg/mL rhLYS		30 mg/mL hLYS
	CFU/mL	% Survival	CFU/mL	% Survival
0	7.5 × 107	100%	7.5 × 107	100%
2	5.3 × 107	70.6%	1.6 × 107	21.3%
4	1.2 × 107	16%	4.8 × 106	6.4%
6	8.7 × 106	11.5%	5.3 × 104	0.07%

H. pylori were treated with 0.3 or 30 mg/mL hLYS for 0, 2, 4 or 6 h. The number of surviving H. pylori cells was determined by cell colony counting.
