To detect pathogens that are capable of causing diseases or infections as postoperative complications in children with congenital heart and kidney disease, to be effective at preventing catheter-associated urinary tract infection. Materials and methods. Clinical material served samples of excrement, urine and urinary catheters of Foley (Unomedica) from sixteen children with congenital heart disease, who were being treated at the Almazov Medical Research Center. The isolated strains were classified according to the identification RapID Systems (USA). Antibiotic sensitivity of isolated bacteria was performed by thedisk diffusion method (NICF, Russia). Scanning electron microscopy (SEM) imaging revealed several types of bacterial communities on intraluminal surface of urethral catheter. Escherichia coli strains were tested for presence of virulence genes a-hemolysin: hly А, В, C by real-time PCR testing (using the detecting amplifier DTlite (DNA Technology, Russia). Results. The main microbial agents were isolated in urines samples from 3 of 16 patients were Staphylococcus aureus and E. coli. Gram-positive cocci were found in 56% samples of excrement and Gram-negative in 44% samples. It was found that on intraluminal surface in 10 out of 16 urethral catheter samples mixed microbial cultures were isolated, S. aureus and E. coli were prevailed. Methicillin-resistant strains of S. aureus (MRSA) have been reported in 85% cases. E. coli a-hemolysin (Ыу А, В, C) were identified in 60% strains. SEM examination two samples of urinary catheters revealed actinomyces-like forms of bacteria that were not detected in the primary bacteriological study. Conclusion. Early diagnosis of catheter-associated urinary tract infections in children with congenital heart heart and kidney disease requires a comprehensive approach to setting detecting priorities and selecting the most effective microbiological analysis, and is mandatory to use modem diagnostic methods.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Выявить потенциальных возбудителей заболеваний, способствующих развитию инфекционного процесса при осложнениях в послеоперационный период у детей с врожденными пороками развития сердца и почек, для разработки эффективной профилактики катетер-ассоциированной мочевой инфекции. Материалы и методы. Клиническим материалом для исследования служили образцы испражнений, мочи и мочевых катетеров Фолея (Unomedica) от шестнадцати детей с врожденными пороками сердца, находившихся на лечении в НМИЦим. В.А.Алмазова. Таксономическую принадлежность выделенных чистых культур определяли, используя идентификационные системы RapID Systems (США). Чувствительность выделенных из клинического материала бактерий кантимикробным препаратам анализировали методом дисков (НИЦФ, Россия). Электронномикроскопический анализ микробных популяций на катетерах проводили, используя сканирующую электронную микроскопию. Полученные культуры Escherichia coli тестировали на наличие генов а-гемолизинов Ыу А, В, С с помощью ПЦР в реальном времени на детектирующем амплификаторе DTlite (ДНК-Технология, Россия). Результаты. В моче у 3 из 16 пациентов выделены Staphylococcus aureus и Е. coli. При посеве испражнений у 56% пациентов обнаружены грамположительные кокки, а у 44% - грамотрицательные палочки. У 10 из 16 пациентов выделены культуры микроорганизмов с внутренней поверхности стенок катетеров; преобладали смешанные культуры, среди которых превалировали S. aureus и Е. coli. 85% штаммов S. aureus, выделенных со стенок мочевых катетеров, проявляли устойчивость к метициллину. У 60% культур Е. coli определены гены а-гемолизинов (Ыу А,В,С), способствующих формированию бактериальных биопленок. При электронно-микроскопическом исследовании в двух образцах мочевых катетеров обнаружены актиномицетоподобные формы бактерий, невыявляемые при первичном бактериологическом исследовании. Заключение. Ранняя диагностика катетер-ассоциированных мочевых инфекций у детей с врожденными пороками развития сердца требует разработки комплексного подхода, включающего наряду с классическим микробиологическим анализом обязательное использование других современных методов диагностики.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Actinotignum</kwd><kwd>congenital heart and kidney disease</kwd><kwd>catheter-associated urinary tract infection</kwd><kwd>hly gene</kwd><kwd>methicillin resistance</kwd><kwd>Actinotignum</kwd><kwd>scanning electron microscopy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>врожденные пороки развития сердца и почек</kwd><kwd>катетер-ассоциированная инфекция</kwd><kwd>ген hla</kwd><kwd>метициллинрезистентность</kwd><kwd>сканирующая микроскопия</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Демикова Н.С., Лапина А.С.
