H. pylori growth and viability was increased under higher glucose level after 48 hr. (A, B) Strain J99 and 43504 grew in Brucella broth containing 10% horse serum and different level of glucose (100, 150, 200 mg/dL). The optical density (OD) at 600 nm of bacterial growth was evaluated during 72 h. (C, D) Colony formation unit (CFU) of strain J99 and 43504 was determined at growth curve of 48 and 72 h. * indicated p < 0.05 (paired t test).
