---|---|---|
H. pylori 18943 wt | Wild type. Clinical isolate from a gastric antrum biopsy. | Culture Collection, University of Göteborg, Sweden (CCUG) |
H. pylori CCUG18943ΔkatA | KmR. Isogenic katA deletion mutant of CCUG18943 was constructed by replacement of katA with nptI. The strain is devoid of KatA expression. | Richter et al., 2016 |
H. pylori P12 wt | Wild type. Clinical isolate from a duodenal ulcer patient. | Schmitt and Haas, 1994 |
H. pylori P12ΔkatA | CmR. Isogenic katA deletion mutant of P12 by cat replacement. The strain is devoid of KatA expression. | This study |
aHelicobacter pylori was grown on chocolate agar or in Brucella broth (Sigma-Aldrich, St. Louis, MO, United States) supplemented with 10% horse serum and 1% Vitox (Oxoid, Hants, United Kingdom) in microaerobic environment at 37°C. Liquid cultures were incubated at 200 rpm. bConcentrations of antibiotics used: 30 μg/ml Kan; 20 μg/ml cm.
