Показано, что внеклеточный матрикс бактериальных биоплёнок, содержит внеклеточную ДНК, несущую маркеры антибиотикоустойчивости. Установлено, что воздействие комплекса ферментов приводит к снижению частоты передачи генов антибиотикоустойчивости в смешанных бактериальных биоплёнках.</p></abstract><trans-abstract xml:lang="en"><p>The effect of the enzyme complex from Vobenzin on transfer of plasmid genes In biofilms of gramnegative bacteria was studied.
