Analysis of Helicobacter pylori Prevalence in Chittagong, Bangladesh, Based on PCR and CLO Test

The pathogenic bacterium Helicobacter pylori is a causative agent of gastric diseases in Bangladesh as well as throughout the world. This study aimed at analyzing the prevalence of H. pylori infection among dyspeptic patients in Chittagong, the second most populous city of Bangladesh, using 16S rRNA-based H. pylori-specific Polymerase Chain Reaction and Campylobacter-like organism test. We found that 67% of the population under study was positive for H. pylori infection. Gastric ulcer and duodenal ulcer disease showed statistically significant association with H. pylori infection; however, no association of H. pylori infection was observed in terms of age and gender. This study would play a crucial role in managing H. pylori-induced gastric diseases by understanding the current trend of H. pylori infection in the Chittagong region of Bangladesh.
