Resistance of Helicobacter pylori to antibacterial medications as a risk factor of infection development

The authors have analyzed research works, both by domestic and foreign researchers that dwell on frequency of H.pylori being resistant to antibacterial medications, the reasons for its occurrence, methods applied to determine it and ways to overcome it. Over the last 15 years there has been a growth in frequency of detecting H.pylori that was resistant to basic antibiotics used to eradicate the pathogen. The authors have established geographical diversity in resistance related to antibiotics intake by population. Bacteriological technique is the most valid for determining H.pylori sensitivity; however, it is rather difficult to apply it due to complicated procedures for the microorganism cultivation. Therefore, molecular-genetic techniques are widely used. H.pylori resistance to Clarithromycin has great practical significance as this antibiotic is able not only to produce antibacterial effects but also to destroy biofilms. Helicobacter that was resistant to Clarithromycin was the least frequently detected in northern European countries (1-3 %); it was the most frequently detected in Southern Europe, Asia, and South America (30-40 %)...
