Wild type H. pylori strains show higher IL-8 production than their isogenic mutant of babA2 in AGS cells. IL-8 from culture supernatant was measured using ELISA as described in “Methods”. Data are expressed as mean ± standard error of mean (SEM) of 3 experiments in duplicates. Wild type is denoted with black filled bar (◼) and mutants denoted with empty bar (◻). *P < 0.05 as compared between groups
