dc.description.abstractGlobally, Helicobacter pylori (H. pylori), a stomach pathogen, is present in around 50 % of the population. This bacterial infection produces persistent inflammation, which significantly raises the risk of duodenal, gastric ulcer, and stomach cancer. The goal of this study is to identify the vacA genotypes in H. pylori and analyze how they relate to medical conditions brought on by the bacteria and clarithromycin resistance. PCR was used to describe 115 endoscopic stomach samples from infected patients and identify vacA gene. Of the 115 research participants, H. pylori was found in 81 (70.4 %) of them. Of the isolated cultures, only 38 (69.1 %) were resistant to clarithromycin. VacA was discovered in 55 (67.9 %) of the samples that had H. pylori in them. Patients with gastritis were more likely to have s2m2 strains of infection (66.7 %), while those with gastric and duodenal ulcers were more likely to have s1m1 strains (64.7 %). VacA-positive H. pylori strains (60 % n = 33) were more resistant to clarithromycin versus (19.2 % n = 5) for vacA-negative bacteria. Clarithromycin resistance was significantly linked to vacA s2m2 in H. pylori isolates (75.9 %). According to the study’s results, the vacA variants s1m1 and s2m2 have a strong connection with the emergence of H. pylori infections that cause peptic ulcer disease in the population of Iraq. Genetic testing is essential in predicting both the course of treatment and the outcome of H. pylori disease.en_US
