[Helicobacter pylori--bacteriologic diagnosis and antibiotic sensitivity tests]

Area of Science:

• Microbiology
• Infectious Diseases
• Gastroenterology

Background:

• Helicobacter pylori infection is a significant global health concern.
• Accurate bacteriological diagnosis is crucial for effective treatment and management.
• Current diagnostic methods vary in specificity, invasiveness, and application.

Purpose of the Study:

• To review and compare various bacteriological diagnostic methods for Helicobacter pylori.
• To highlight the advantages and limitations of each diagnostic approach.
• To provide guidance on selecting appropriate diagnostic methods based on clinical context.

Main Methods:

• Review of established bacteriological diagnostic techniques for H. pylori.
• Discussion of culture methods using gastric biopsies, gastric juice, and feces.
• Evaluation of antigen stool assays and molecular diagnostic approaches.

Main Results:

• Gastric biopsy culture is the most specific diagnostic method and enables drug sensitivity testing.
• Antigen stool assay is a non-invasive option requiring further evaluation.
• Molecular methods show promise for epidemiological studies and detecting macrolide resistance.

Conclusions:

• Culture from gastric biopsies remains the gold standard for H. pylori diagnosis due to its specificity and ability to guide therapy.
• Non-invasive methods like antigen stool assay and molecular diagnostics offer complementary roles, particularly in research and resistance detection.
• The choice of diagnostic method should be guided by clinical setting, availability, and economic factors.
