Risk factors causing the development of infection and inflammation of the lower urinary tract

Cover Page

Abstract


Persistence as well as high survival rate and resistance of microorganisms belong to the key reasons promoting symptoms of lower urinary tract diseases. They can stay active for a long time and can substantially deteriorate the life quality of patients suffering from chronic infections and inflammations in the wall of the urinary bladder even after the eradication of the pathogen. Recent studies in the field of clinical microbiology reflect serious qualitative and quantitative changes in the infection incidence structure, which is mainly related to changes in the bacterial pathogenicity. Pathogenicity island genes control the synthesis of different adhesins, invasins, hemolysins and toxins (hemolysin, cytotoxic necrotizing factor type 1, etc.) as well as iron ion absorption system, which are essential for the pathogen propagation and activity in tissues. The determination of genetic determinants will provide a new insight into the bacterial evolution process and will help to understand the reason of prompt formation and propagation of virulent strains as well as fast development of the infection and inflammation in the lower urinary tract, which may explain different severity of the pathology and symptoms of the lower urinary tract.
