Identification Methods of Helicobacter Pylori Bacteria

Abstract

Background: Helicobacter pylori is a well-known carcinogenic pathogen associated with gastrointestinal diseases, often infecting individuals during childhood and persisting asymptomatically for years. Specific Background: The failure to diagnose H. pylori early can result in severe health consequences, making timely and accurate diagnosis critical to preventing its spread. Knowledge Gap: Diagnostic methods' effectiveness depends on patient age, economic status, and operator skill, with some tests being expensive and influenced by protocol adherence. Aims: The study evaluates the efficacy of various diagnostic methods for H. pylori, focusing on the accuracy, reliability, and practicality of invasive and non-invasive techniques. Results: Invasive methods like histology, endoscopy, culture, rapid urease test, and polymerase chain reaction (PCR) provide direct detection of the bacterium, while non-invasive methods such as the urea breath test, stool antigen assay, and serology offer indirect detection without requiring endoscopy. PCR, when conducted with appropriate primers and gene targets, remains the most accurate diagnostic tool. Novelty: The study emphasizes the superior diagnostic value of PCR due to its precision, despite challenges related to operator skill and procedural compliance. Implications: The study emphasizes the significance of selecting suitable diagnostic methods based on patient-specific factors and the need for skilled execution for accurate results in managing and treating H. pylori infections. Highlights:   PCR Accuracy: Most reliable H. pylori test with correct primers and targets. Operator Skill: Diagnosis depends on skilled execution and procedural adherence. Test Selection: Choose based on patient age, economic status, and method availability.   Keywords: Helicobacter pylori, diagnosis, gastrointestinal diseases, PCR, invasive tests
