Antibiotic resistance and cagA gene correlation: A looming crisis of Helicobacter pylori

Figure 3 The trend analysis antimicrobial drug resistance in Helicobacter pylori strains (n = 178). A: From 2005 to 2008, significant increase in clarithromycin resistance was observed by linear regression (P = 0.004); B: Correlation of drug resistant strains in various groups of patients. Significant distribution of metronidazole (P = 0.001), clarithromycin (P < 0.000) and amoxicillin (P = 0.005) resistance was observed by Pearson’s χ² test. NUD: Non ulcerative dyspepsia; GU: Gastric ulcer; DU: Duodenal ulcer.
