From: Helicobacter pylori lipopolysaccharide modification, Lewis antigen expression, and gastric colonization are cholesterol-dependent

Figure 3

H. pylori grown without cholesterol fail to colonize gerbils. H. pylori strain SS1 was grown overnight in defined medium containing 0 or 50 μg/ml cholesterol. Gerbils were orally inoculated with 3.5 × 108 CFU (experiment A) or 1 × 108 CFU (experiment B). H. pylori in gastric antrum were quantitated at 11 days. Each vertical bar represents the mean of duplicate determinations for one animal, and horizontal lines give the median for each treatment group. Where no colonies were recovered, values were recorded as 5 × 102 CFU/g tissue, the estimated limit of detection.
